Huge Risks for the proposed $500B AI Investments from Giant Wall Street firms

……………………………………………………………………………………………………………………..

Executive Summary:

This past Monday, six giant Wall Street asset managers, private-equity firms and banks announced an effort to raise $500 billion to keep fueling the A.I. boom by financing more data centers, power plants and chips. The proposed platform would direct capital to Nvidia customers—including AI startups and data-center operators—at precisely the point when many have struggled to obtain funding through ordinary credit channels.

We take that as a huge warning sign for the proposed AI investments. Here’s why: If the underlying projects offered clearly proven cash flows, predictable utilization and collateral with durable value, lenders would not need a specially assembled consortium, headline-scale commitments and Nvidia’s direct involvement to make the loans happen. The initiative appears designed to overcome a financing bottleneck created by the extraordinary gap between AI infrastructure spending and demonstrated AI revenue.

This proposed $500 billion AI-financing initiative is less a validation of durable AI economics than an admission that the sector’s spending plans have outgrown its customers’ ability—or willingness—to finance them conventionally. Rather than demonstrating independently sustainable demand, the arrangement risks extending an investment cycle increasingly dependent on vendor-enabled credit, opaque commitments and financial engineering.

The firms—Apollo, BlackRock, Blackstone, Brookfield, Goldman Sachs and KKR—said they were working together to come up with that huge sum to lend to Nvidia’s customers, including the start-ups that use the company’s chips in data centers to develop and operate A.I. software. These customers, Nvidia said, have been struggling to secure financing for chips and data centers.

Nvidia will connect its customers with one of the six lenders, which will provide financing that could range from loans to credit. The financing will be “at attractive rates,” Nvidia said in a blog post.

In practical terms, this is a vendor-financing mechanism, even if the capital technically comes from third parties. Nvidia is helping its customers obtain the money required to buy Nvidia-dependent infrastructure. The more readily startups and data-center operators can borrow, the more equipment they can order; the more equipment they order, the more Nvidia can sell. That does not mean the demand is fictitious, but it does make it harder to distinguish independent end-user demand from demand supported by an ecosystem that is financing itself.

Circularity is the principal concern. When suppliers, investors, cloud providers, AI labs and lenders all have financial incentives to keep capital circulating within the same small group of counterparties, reported growth can look more robust than the ultimate economics justify. The risk is not simply that projects fail individually. It is that a shortfall in AI-service revenues, utilization or pricing could spread simultaneously through hardware vendors, AI developers, cloud operators, private-credit vehicles and the securities backed by their cash flows. Circular financing can blur the line between real external demand and investment-funded purchases.

Executives from the lenders joined Jensen Huang, Nvidia’s CEO & founder, for an unusual, extended interview on CNBC, where they talked up their new, seemingly insatiable desire to finance infrastructure for A.I. Huang said on the air. He added that “A.I. labs” and “A.I. start-ups” would have access to the financing. He did not name those companies or whether Nvidia would receive any money as part of the effort. David M. Solomon, Goldman’s chief executive, said the consortium was Mr. Huang’s idea.

“We need to raise this money as fast as possible,” said Larry Fink, BlackRock’s chief executive. He also stated: “There’s quite a bit of negativity around A.I. and data centers right now, but let’s be clear: This is going to be creating a huge amount of jobs.”

Skeptical Analysis:

The urgency in those statements deserves more scrutiny. Speed is not a substitute for underwriting, and job-creation claims do not establish that investments will meet their cost of capital. The industry is attempting to finance assets whose useful economic life may be much shorter and more uncertain than that of traditional infrastructure. A GPU fleet can lose competitiveness rapidly when a new architecture, memory standard or systems design emerges. Its resale value can fall sharply if capacity demand weakens. Treating such hardware as collateral comparable to a toll road, utility asset or long-lived building is a major assumption—not an established fact.

The announcement punctuates a head rush on Wall Street and in Silicon Valley into anything that even vaguely resembles A.I. The stocks of tech giants and chipmakers have soared for most of this year, and a pair of the biggest names in the space, Anthropic and OpenAI, are expected to file for initial public offerings that could value them at $1 trillion apiece.

But soaring equity valuations and enormous projected IPO valuations do not answer the basic return-on-investment question: who will pay enough, for long enough, to justify the total cost of the data centers, power plants, networking, GPUs and debt now being assembled? AI vendors may generate impressive revenue growth while still failing to earn enough to cover the depreciation, energy, financing and replacement costs of the infrastructure required to produce it.

Nvidia’s financing narrative appears to conflate broad interest in AI-enabled services with broad, independent demand for capital-intensive AI infrastructure. Governments, enterprises and startups may all seek access to AI capabilities, but the current demand for hyperscale GPU clusters, dedicated power capacity and purpose-built “AI factories” remains concentrated among a relatively small group of frontier-model developers and cloud platforms.

That distinction matters because broad adoption of AI applications does not automatically translate into economically sustainable demand for vast new data-center capacity. Enterprises can consume AI through APIs, hosted platforms, smaller models and open-source software without owning—or financing—dedicated high-density compute infrastructure. Nvidia itself describes demand as spanning enterprises, startups, governments, nations and AI labs, but the critical question for investors is how much of that demand converts into durable, contracted infrastructure revenue rather than experimentation, pilots or subsidized consumption.

As Bloomberg reported last week, OpenAI accounted for somewhere between 50% and 70% of Microsoft’s AI revenue in the 12 months to 30 June.

That degree of concentration is significant. Microsoft disclosed $24.1 billion in sales from OpenAI during the year ended in June; outside estimates place that at more than half, and perhaps about 70%, of Microsoft’s AI-related revenue. Much of the revenue reflects OpenAI’s spending on Microsoft cloud and model-development services, meaning a substantial portion of the apparent AI revenue base may be generated within a tightly linked commercial relationship rather than by a diversified population of external enterprise customers.

That could be problematic if the picture is similar at other hyperscalers and at other frontier AI companies like Anthropic, for example. A market in which a handful of loss-making model developers drive an outsized share of cloud and infrastructure revenue is inherently more fragile than one supported by a broad base of profitable end users. It exposes infrastructure providers and lenders to customer concentration, correlated capital spending and the possibility that a reduction in financing at one frontier lab quickly reduces demand across the supply chain.

Indeed, as has been reported by multiple correspondents – most notably staunch AI critic Ed Zitron – LLM makers like OpenAI are losing money hand over fist and can only charge so much for tokens before customers either curb their usage or switch to open source models. Zitron wrote:

“It’s estimated that 70% or more of the AI revenues of Microsoft, Google, and Amazon were from either OpenAI or Anthropic. UBS estimated that next year, Anthropic and OpenAI’s compute spend would be 48% of all Google Cloud revenues — which means that they likely account for even more than 70% of its AI revenues.”

The commercial challenge is not whether frontier models have value- they do. It is whether they can deliver that value at prices that exceed the combined costs of training, inference, electricity, networking, cloud capacity, depreciation and ongoing model development. If token pricing rises too far, customers may reduce usage, shift workloads to lower-cost models, or use open-source alternatives. If pricing remains low, frontier-model providers may struggle to cover their infrastructure bills. Open-source fine-tuning can materially reduce costs for specialized enterprise workloads, reinforcing the competitive pressure on premium proprietary-model pricing.

The most plausible downside is that the technology becomes broadly useful but insufficiently profitable to support today’s extreme capital intensity. That outcome would leave the sector with too much high-cost capacity, thin margins, declining GPU collateral values and lenders dependent on assumptions about utilization and cash flows that have not yet been tested through a downturn. The foundational financial risk is straightforward: AI-service revenues may prove insufficient to service the fixed obligations incurred to construct the infrastructure. Notably, Nvidia stock dipped modestly on Monday after The Financial Times reported that the company was nearing the mammoth financing deal.

While the contours of the arrangements were announced Monday afternoon, details remained scarce. A joint news release referred only to “memorandums of understanding” to “create dedicated pools of capital at significant scale.”

That language is important. Memorandums of Understanding (MoU’s) are not equivalent to binding, fully funded commitments. Until investors know the actual terms—capital committed, leverage permitted, collateral requirements, Nvidia’s role in losses, loan maturities, customer concentration limits and underwriting standards—the $500 billion figure is better understood as an ambitious financing target than as validated capital deployment. Reporting has described the initiative as a multiyear target rather than cash already committed, while questions remain about the scale of any Nvidia backstop.

During their television interview, the lenders’ executives alluded vaguely to “yield-based products” and even securitization, or the creation of bonds that would divvy up the revenue from A.I. labs into risky and less risky categories. There were several references to A.I. as a new asset class and to allowing smaller investors an opportunity to invest in debt backed by the data centers.

This is where the proposal moves from aggressive investment to potential systemic-risk creation. Securitization can distribute risk, but it does not eliminate it; it can instead diffuse difficult-to-value exposure across a wider investor base. Packaging AI-data-center debt into yield products may make financing more available, but it also risks obscuring the quality of the underlying cash flows, the degree of correlated exposure among borrowers and the vulnerability of rapidly depreciating hardware collateral. The more complex the capital stack becomes, the greater the danger that investors mistake engineered liquidity for genuine economic value.

Executive Quotes:

“NVIDIA has reached an important milestone. We began by building chips; today, we are helping create a new class of productive, investable infrastructure: AI factories,” said Jensen Huang, founder and CEO of NVIDIA. “In AI, compute is revenue. NVIDIA compute is uniquely suited for this role. It is broadly adopted, flexible across models and workloads, fungible and transferable across customers and operators, and continuously improved through CUDA software — extending its useful life and improving its economics over time. It is supported by a deep global ecosystem of developers, customers and offtakers. That is why we are bringing the world’s leading long-term capital providers together to independently underwrite AI infrastructure. These financing platforms will help customers access scarce compute at scale and build the DSX AI factories that will power every industry and country in the age of AI.”

“Modern compute has emerged as a scarce, mission-critical asset class with compelling investment characteristics that is positioned to drive significant long-term economic growth and productivity gains,” said Apollo President Jim Zelter. “The combination of NVIDIA’s proprietary technology ecosystem and Apollo’s flexible, long-term capital base provides a strong foundation to support the next stage of the AI buildout as part of the broader Global Industrial Renaissance.”

“The AI buildout will require unprecedented investment and a skilled workforce to turn that investment into the infrastructure that will help power future growth,” said Larry Fink, Chairman and CEO of BlackRock. “This partnership deepens our relationship with NVIDIA, including through the AI Infrastructure Partnership, and brings together NVIDIA’s leadership in accelerated computing with BlackRock’s ability to connect long-term capital to essential infrastructure. Together, we can help deliver the compute capacity that companies need to grow and create more jobs, supporting the continued growth of the U.S. and global economies, while creating attractive, long-term investment opportunities for our clients.”

“NVIDIA has created extraordinary demand for its compute through an intense focus on customer value and versatile technology,” said Jon Gray, President and COO of Blackstone. “We continue to be enormous investors globally across the NVIDIA ecosystem, and this announcement further underscores our confidence in their platform and the future of AI infrastructure.”

“As our strategic partner, NVIDIA is enabling us to scale AI factories. We are excited about further collaboration to build and fund the backbone of AI globally,” said Bruce Flatt, CEO of Brookfield. “With demand for large-scale AI compute growing significantly as adoption scales across industries, compute is fast becoming the essential layer of infrastructure and a core pillar of the Brookfield AI infrastructure strategy.”

“We’re in a pivotal moment of a historic AI investment cycle. NVIDIA’s full-stack platform is in high demand and uniquely positioned at the center of that global buildout,” said David Solomon, Chairman and CEO of Goldman Sachs. “Our investment and distribution roles reflect our confidence in NVIDIA’s leadership, and we’re excited for the new opportunity to create a market for credit backed by NVIDIA compute.”

“Compute has become a critical infrastructure asset. As we’ve scaled our approach to digital infrastructure, we’ve learned that delivery, not ambition, is the hard part. That’s why we’re excited to build on our strategic partnership with NVIDIA, a founding investor in Helix Digital Infrastructure, to bring together NVIDIA’s accelerated computing platform with KKR’s long-duration capital, infrastructure expertise and capital markets capabilities to turn growing demand into real capacity at extraordinary scale,” said Joe Bae and Scott Nuttall, Co-Chief Executive Officers of KKR.

“This is the very beginning — like what it was when I started in the mortgage-backed securities market in the 1970s,” Mr. Fink said. “I look upon this as a next future for financial engineering.”

That analogy should be treated as cautionary, not reassuring. Financial engineering can expand access to capital and spread risk efficiently when assets have transparent valuations, stable cash flows and conservative underwriting. It becomes dangerous when it is used to finance unproven revenue models, rapidly obsolescing assets and demand forecasts that must remain exceptionally optimistic simply to justify the initial investment.

Huge Risks Explained:

If AI demand stalls, Nvidia faces a sharp reversal in hardware demand and a potentially damaging credit overhang, while lenders could be left financing underutilized data centers secured by equipment whose value can decline far faster than conventional infrastructure. The common vulnerability is that the same uncertain AI revenue streams would be expected to support chip purchases, data-center leases, project debt and securitized investment products. Nvidia is especially exposed to risks:

Order cancellations and lower pricing power. Cloud providers, AI labs and startups would likely slow GPU orders, defer deployments or renegotiate capacity commitments. Nvidia could face weaker revenue growth, inventory risk and pressure on the high margins that have supported its valuation.
Vendor-financing and counterparty risk. If Nvidia is arranging or backstopping financing for customers buying its systems, a demand slowdown could turn what appeared to be hardware sales into indirect credit exposure. Customers unable to earn adequate returns from AI services may struggle to repay loans used to buy Nvidia equipment. The risk is magnified where the company’s commercial success depends on borrowers gaining access to financing in the first place.247wallst+1
Collateral impairment. GPUs are not durable, slow-depreciating infrastructure assets. A new chip generation, a shift toward more efficient models, or weak utilization can materially reduce the resale value of installed systems. If lenders rely on those systems as collateral, a default could leave them holding equipment worth substantially less than the loan balance—and Nvidia could face lower demand for both new and prior-generation products. Moody’s identifies rapid capacity expansion and fast-changing chips, cooling and computing architectures as sources of overbuilding and technology-obsolescence risk.moodys
Feedback-loop risk. A slowdown could create a negative cycle: AI customers reduce spending; Nvidia’s sales weaken; lenders become more cautious; financing availability tightens; customers cut orders further. Where vendors, customers and capital providers are financially intertwined, the decline can be more abrupt than a normal inventory correction.
Equity-valuation risk. Nvidia’s market value reflects unusually strong assumptions about the longevity of AI spending, margins and growth. A reassessment of those assumptions could compress the valuation sharply even if Nvidia remains profitable. BIS warns that disappointment in AI returns could trigger a sudden financing pullback and turn the capex boom into a prolonged investment bust.bis

Lenders’ exposure:

Risk	How a demand stall transmits losses
Default risk	AI labs, cloud operators and data-center developers may fail to generate enough revenue to cover interest, principal, energy and operating costs.
Underutilized capacity	Empty or lightly used data halls produce far less cash flow than underwriting models assume, impairing debt-service coverage.
Collateral-value risk	Specialized GPU, networking and cooling systems may have weak resale value in a downturn, especially if many borrowers liquidate comparable equipment simultaneously.
Refinancing risk	Projects commonly require follow-on funding after construction. If markets reprice AI risk, borrowers may be unable to refinance maturing debt except at much higher rates—or at all.
Concentration risk	Multiple loans, funds and securitizations may rely on a small number of AI labs, hyperscalers, equipment suppliers and power projects. A weakness in one tenant or customer can affect many nominally separate investments.
Structured-finance risk	Securitizing data-center revenues can spread exposure across private-credit funds, insurers, pensions and bondholders. It diversifies ownership of the risk, but does not improve the underlying cash flow.

The most immediate lender risk is a mismatch between long-lived debt obligations and unstable, technology-dependent revenue. A data center might be financed over many years, but its GPU fleet may need continual upgrades to remain competitive—requiring additional capital expenditure before the original debt is repaid. Moody’s notes that this combination of increasing capital intensity, uncertain compute requirements and structured finance can pressure developers, landlords and investors through execution, renewal and refinancing risk.moodys

Construction and power risks:

A demand slowdown could arrive before projects enter service. That creates a particularly difficult situation for lenders because construction interest, cost overruns and power-reservation charges may accumulate before revenue begins.

Permitting delays, local opposition, water constraints and electricity-grid limitations further compound this exposure. Reuters reported that lenders increasingly treat project readiness—including approvals, permits and local community support—as a credit factor because delays can increase costs, jeopardize covenants and prevent projects from reaching revenue-generating operation.

System-wide scenario:

The more serious scenario is a correlated unwind:

AI applications fail to deliver enough monetizable demand.
AI labs and cloud providers reduce compute commitments.
Data-center utilization and expected rental income fall.
Borrowers cannot service or refinance project debt.
GPUs and related infrastructure lose collateral value.
Losses reach private-credit funds, banks, securitized vehicles, insurers and institutional investors.
New financing becomes unavailable, causing further cuts in infrastructure orders and Nvidia sales.

This would not necessarily resemble the 2008 banking crisis: some first-loss exposure sits outside regulated banks. But Chicago Booth research estimates that a severe re-rating of AI-related debt could still produce roughly $60 billion to $140 billion in realized credit losses, alongside large equity-market effects.

What matters most:

The decisive question is not whether AI is useful or whether data centers remain necessary. It is whether cash-paying end users will generate sufficient, durable revenue to justify the full cost of the hardware, power, real estate, construction and financing now being committed. If that answer is no, the sector may discover that it financed capacity—not returns.

Telefónica incorporates AI for businesses voice communications vs. 3GPP/ITU specifications

Posted on August 11, 2026 by Alan Weissberger

Executive Summary:

Telefónica España made an announcement this week which indicates that Voice could be an important AI monetization opportunity for telcos. The Spain based telecom group is positioning its business voice portfolio around a key differentiator: the ability to embed AI-enabled capabilities directly into conventional fixed and mobile telephony, without requiring enterprises to migrate users or workflows to a separate communications platform. It is incorporating generative AI features into its network for things like call transcription and summarization, which it says is will transform “every voice conversation into usable, structured and actionable information,” as week as virtual assistants on fixed-line and mobile.

Targeted at large enterprises, public-sector organizations, and mid-sized businesses, the enhanced portfolio is intended to shorten call-response times, increase the proportion of calls handled, and convert voice interactions into structured, actionable business information. Telefónica reports that the AI-enabled tools can reduce time spent managing calls by an average of 60%, enabling organizations to handle a higher volume of customer interactions.

Telefónica has integrated artificial intelligence across its business voice offerings—from basic mobile services to advanced PBX and cloud-based telephony platforms—as part of its evolution toward intelligent voice communications. The proposal incorporates generative-AI functions within the Telefónica network, including call transcription, automated summarization, and virtual-agent capabilities. These functions are designed to preserve information that might otherwise remain unstructured within voice conversations, while helping organizations reduce missed opportunities and improve operational responsiveness.

Javier Pascual, Director of Product, Pre-sales and Provisioning at Telefónica Spain, said:

“We are the only operator that offers intelligent transcription and summarization of calls over fixed and mobile voice, making us the best way for companies to access digital technologies. This pioneering solution, which integrates generative AI into standard telephony, allows our clients to summarize and transcribe calls, as well as integrate 100% of virtual agents using natural language, thus improving productivity and agility.”

Cross-Portfolio Intelligent Voice:

Telefónica’s approach spans enterprise, public-administration, corporate-mobile, and mid-market customer segments. It applies to traditional and cloud-based voice solutions, including:

Centrex IP, Telefónica’s converged fixed-mobile business voice platform.
Centrex 365, a Microsoft-based cloud voice offering integrated with collaboration tools.
Enterprise mobile voice services.

A core capability is AI-based transcription and summarization of calls. By transforming voice conversations into searchable and structured records, the feature can support knowledge capture, customer-service follow-up, compliance-related documentation, and analytics workflows.

The company is also introducing Centrex AI, a virtual-agent capability based on advanced language models. Centrex AI is designed to support next-generation generative-AI interactions across channels beyond voice and to integrate with customer business applications. The virtual agents are intended to interpret natural-language requests in context, automate repetitive interactions, and provide faster, more consistent responses.

Telefónica states that the platform supports more than 100 languages and can operate continuously, enabling 24/7 multilingual customer engagement.

Operational and Vertical Use Cases:

Telefónica reports that the AI-enabled capabilities can improve agent efficiency by as much as 60% by reducing time devoted to repetitive tasks. The company also cites potential increases of more than 10% in the number of interactions managed, reflecting improved call-handling capacity.

Initial use cases focus on healthcare, public administration, retail, and industrial enterprises:

In healthcare, a WhatsApp-based AI agent can schedule appointments, provide immediate confirmations, and support multilingual exchanges.
For municipal governments, voice agents can address common citizen queries in multiple languages and route calls to the appropriate department.
For automotive dealerships, virtual agents can help manage service appointments and customer inquiries related to vehicle sales.

By integrating generative AI functions into the existing voice network and service portfolio, Telefónica is seeking to extend intelligent automation to established telephony environments rather than treating AI communications as a standalone application layer.

…………………………………………………………………………………………………………………………………….

Editorial Analysis:

Telefónica’s offer as an operator-integrated, proprietary AI overlay on existing fixed/mobile and cloud voice services, rather than as a service defined by 3GPP or ITU. The business voice offering builds on standardized fixed/mobile voice and cloud-telephony foundations, while its generative-AI functions—call transcription, summarization, and virtual-agent integration—appear to be operator- and vendor-implemented capabilities. Current 3GPP work provides enabling mechanisms for AI/ML in 5G systems, whereas ITU-R’s AI-related IMT work addresses radio-network evolution rather than AI-enhanced enterprise telephony.3GPP.

Relevant 3GPP specifications:

Specification	Relevance to AI voice/telephony	Limitation
TS 22.243, Speech recognition framework for automated voice services	The closest direct 3GPP specification. It defines Stage-1 service requirements for speech-recognition-enabled automated voice services. 3gpp	It predates contemporary GenAI and does not specify LLM-based transcription, summarization, virtual agents, or a network-resident AI voice platform.
TS 28.105, Management and orchestration; AI/ML management	Specifies management aspects for AI/ML in 5G systems, including lifecycle-oriented operator control of AI/ML capabilities. 3gpp	It concerns network AI/ML management, not the application-layer behavior of an enterprise voice assistant.
TS 28.104, Management Data Analytics	Provides the management-data-analytics foundation that can support closed-loop network automation and AI/ML operations. 3gpp	Not a voice-service or customer-interaction specification.
TR 23.700-80, Study on 5G system support for AI/ML-based services	Examines 5GS support for AI/ML-based services. 3gpp	A Technical Report is study material, not a normative implementation specification.
TR 23.700-82/-83, Application layer support for AI/ML services	Relevant to application-layer AI/ML enablement, potentially including applications that use voice input or output. 3gpp	These are horizontal AI-service studies rather than specifications for AI-enhanced IMS, VoNR, or enterprise telephony.
TS 23.482, Functional architecture and information flows for AIML Enablement Service	A more recent normative architectural direction for an AI/ML enablement service in the 5G system. 3gpp	Still not a standardized “AI calling” feature set or common API for call transcription and summarization.

3GPP’s AI/ML work is primarily focused on network and RAN optimization, AI/ML model transfer and lifecycle management, data collection, and interoperability. Notably, 3GPP has stated that it does not plan to standardize the AI/ML models themselves; it instead standardizes the supporting mechanisms and controls.3gpp

ITU-R versus ITU-T:

ITU-R: There are no ITU-R Recommendations specifically governing AI-based telephony, generative-AI call summarization, or virtual agents. This is consistent with ITU-R’s mission: spectrum, radio propagation, and IMT radio-interface frameworks. Its IMT-2030/6G work includes integrated AI and communication as a broad capability area, but that concerns wireless-system capabilities such as distributed training and inference—not enterprise voice-service features.

ITU-T: This is the more relevant ITU sector for AI telephony and conversational AI, although its work is still largely horizontal rather than specific to IMS/PSTN calling:

ITU-T F.748.46 (2025) specifies requirements and evaluation methods for AI agents based on large-scale pre-trained models. Its scope includes recognition, comprehension, dialogue, generation, and reasoning—capabilities directly relevant to virtual voice agents.
ITU-T E.AIQ, Framework for quality evaluation of conversational AI systems, is under study in Study Group 12. It proposes KPIs and an “AI Quotient” approach for assessing AI systems in relation to QoS and QoE.itu
ITU-T Y.3178 defines a functional framework for AI-based network-service provisioning in future networks.itu
ITU-T Y.3661 (2025) specifies an architecture and mechanisms for customer-oriented intelligent network operation, including AI-supported recognition of user intent; this is adjacent to, but not a telephony-service specification

Dell’Oro: Enterprise PON Deployments expected to increase 844% year-over-year

Posted on August 10, 2026 by Alan Weissberger

According to a new Dell’Oro Group report, “PON in the Data Center and Premise Advanced Research Report“ recently published, total 2026 Data Center PON equipment revenues are expected to increase 844% year-over-year (Y/Y), driven by hyperscalers looking to use the point-to-multipoint technologies to reduce the cabling and power consumption requirements of their out-of-band management networks.

“PON technologies are increasingly moving from traditional residential networks to enterprise and data center applications, providing additional growth opportunities for PON equipment providers,” said Jeff Heynen, Vice President of Broadband Access and Home Networking market research at Dell’Oro Group. “We see hyperscalers and enterprises, both large and small, increasingly deploying PON technologies for passive fiber distribution that is lower cost and that maintains its value far longer than traditional copper infrastructure,” added Heynen.

Additional highlights from the PON in the Data Center and Premise Advanced Research Report:

Total cumulative spending on data center PON equipment from 2026 to 2030 is expected to exceed $3 billion, as hyperscalers, neocloud providers, and colocation providers all deploy PON for their out-of-band and infrastructure management networks.
Enterprises are increasingly deploying Passive Optical LAN (POL) as the long-term benefits of increased speeds and lower operational costs outweigh the costs of deploying fiber in the building.
Chinese operators continue to deploy tens of millions of master and subtended ONTs to deliver fiber-to-the-room (FTTR) services to their residential broadband customers.

Editorial Analysis:

This extremely bullish forecast points to a potentially important new use case for PON: not as a replacement for the high-bandwidth, low-latency Ethernet fabric that interconnects servers and storage, but as an economical physical layer for the separate networks used to monitor, provision, and recover data-center infrastructure. In that role, a passive optical distribution architecture can consolidate fiber runs and avoid electrically powered aggregation equipment in parts of the management network, potentially simplifying expansion and reducing operational overhead.

Dell’Oro’s projected 844% year-over-year revenue increase should be read in the context of an early-stage market: the percentage reflects rapid adoption from a comparatively small base rather than an indication that PON will displace mainstream data-center switching. Nevertheless, the report’s forecast of more than $3 billion in cumulative 2026–2030 spending indicates that hyperscale, neocloud, and colocation operators are sufficiently interested to make data-center PON a material adjacent market for OLT, ONT, and ONU suppliers.

The enterprise opportunity is somewhat different. Passive Optical LAN can extend fiber deeper into commercial buildings, with optical terminals serving end-user areas rather than relying entirely on copper horizontal cabling and access switches. The principal trade-off is front-loaded installation complexity—especially where fiber pathways must be added or upgraded—against the prospect of longer infrastructure life, higher available access speeds, and lower energy use over the building lifecycle. Dell’Oro also includes enterprise/MDU POL and business FTTR applications in its five-year forecast coverage, suggesting that it views these segments as part of the same widening PON equipment ecosystem.

China’s large-scale FTTR deployments provide a useful volume counterweight to these specialized data-center and enterprise applications. Master and subtended ONT architectures enable operators to extend fiber connectivity from the residence gateway to individual rooms, creating another demand source for optical endpoints and related PON equipment. Together, these developments suggest that future PON market growth will depend increasingly on diversification beyond conventional residential FTTH—while also requiring vendors to address application-specific management, installation, and interoperability requirements.

About the Report

The Dell’Oro Group PON in the Data Center and Premise Advanced Research Report includes 5-year market forecasts for PON Optical Line Terminals (OLTs), and PON Optical Network Terminals (ONTs) and Optical Network Units (ONUs) used in Data Center [Out-of-band management (OOBM), infrastructure management (DCIM)], Enterprise/MDU [Passive Optical LAN (POL), Fiber-to-the-room for business (FTTR-B)] , and Fiber-to-the room (FTTR) applications.

Posted on August 9, 2026 by Alan Weissberger

Executive Summary:

AT&T has selected Ericsson to supply 600 MHz dual-band radios for deployment of the low-band spectrum it recently acquired from EchoStar. The equipment choice is notable not simply because it activates new spectrum, but because it enables AT&T to introduce uplink-enhancing eight-receiver (8RX) technology across its low-band holdings for the first time. AT&T says it will disclose rollout timing and commercial-availability plans later.

—>By selecting Ericsson’s dual-band radios for its newly acquired 600 MHz holdings, AT&T is moving from spectrum ownership to the more consequential task of operationalizing low-band capacity across its entire RAN.

Spectrum Is Not a Network:

The announcement illustrates an elementary but sometimes overlooked fact of mobile-network economics: a spectrum license is not yet a network capability. It becomes one only when an operator has compatible radios, antennas, baseband and transport resources, site access, configuration, optimization, and a viable deployment program.

AT&T’s EchoStar acquisition delivered approximately 20 MHz of nationwide 600 MHz spectrum alongside 30 MHz of 3.45 GHz mid-band spectrum. The mid-band component could be put into service comparatively quickly, while the 600 MHz component required radio equipment that AT&T had not previously deployed at scale. That hardware gap makes the Ericsson selection an operational milestone rather than a routine vendor purchase.lightreading+1

Ericsson’s selected radios support both 600 MHz Band 71 and 700 MHz Band 14—the latter associated with FirstNet. This dual-band approach potentially lets AT&T refresh or augment low-band radio infrastructure while adding a new frequency layer, rather than treating the 600 MHz deployment as a stand-alone overlay.fierce-network

Why 600 MHz Matters:

Spectrum below 1 GHz is valuable principally for propagation rather than for peak throughput. A 600 MHz signal can generally cover a wider geographic area and penetrate buildings better than mid-band spectrum, which makes it especially useful for rural coverage, suburban edge coverage, indoor service, and reliability-oriented capacity layers. AT&T and Ericsson characterize the deployment as improving capacity, reliability, coverage, and overall network performance.ericsson+1

That does not mean 600 MHz should be viewed as a substitute for mid-band 5G capacity. With a nationwide block of roughly 20 MHz, AT&T’s 600 MHz spectrum is unlikely to match the raw throughput potential of wider mid-band channels. Its strategic value lies instead in extending a dependable coverage foundation to locations where higher-frequency spectrum either reaches fewer users per site or suffers greater indoor loss.

In this respect, the acquisition and radio deployment form a complementary two-layer strategy. The 3.45 GHz spectrum can add substantial metropolitan and suburban capacity, while 600 MHz strengthens the wide-area and in-building layer beneath it. The relevant measure of success will therefore not be a single peak-speed benchmark, but whether AT&T can improve user experience at the cell edge, indoors, and in markets where macro-site density is inherently limited.

The 8RX Uplink Dimension:

The technically distinctive part of the announcement is AT&T’s plan to deploy 8RX technology across low bands for the first time. In simplified terms, 8RX refers to use of eight receive paths at the base station. This can improve the network’s ability to receive signals transmitted by user equipment, improving uplink link budget, interference handling, and potentially uplink capacity or consistency. 8RX improves uplink because the base station has eight receive branches—rather than the four normally used for low-band FDD radios—to hear and separate signals sent by handsets. More receive branches improve receiver diversity, spatial interference rejection, and link budget, especially for weak uplink transmissions at the cell edge or indoors.

This matters because mobile usage is no longer overwhelmingly downlink-centric. Consumers upload high-resolution video, participate in real-time communications, share content, use cloud applications, and increasingly interact with AI-enabled services that may generate meaningful upstream traffic. Enterprises also depend on upstream performance for field video, surveillance, industrial devices, connected vehicles, and edge-to-cloud telemetry.

Low-band FDD deployments commonly use four receiver paths; moving to 8RX can therefore increase the base-station receive capability at the coverage layer where user devices are most likely to operate at weak-signal conditions. Light Reading reported that AT&T views the Ericsson radio selection as a means to introduce this uplink-enhancing configuration across its low-band spectrum, although performance results and deployment scope remain to be demonstrated in the field.

The important caveat is that 8RX does not create spectrum. Its contribution is to improve how effectively the network uses the uplink resources it has, particularly where coverage, interference, or link budget constrain the user’s transmitted signal. The realized benefit will depend on radio design, antenna implementation, spectrum configuration, device capability, traffic mix, and local RF conditions. See Addendum.

A Modernization Program, Not an Isolated Upgrade:

AT&T frames the effort as part of a wider network-modernization program. The company says upgraded Ericsson infrastructure has already delivered up to two-times faster average speeds in relevant areas, a 10% reduction in dropped or blocked calls, fewer slow-speed incidents, and lower uplink interference; these are operator-reported figures and should not be generalized to the forthcoming 600 MHz layer until independently validated.

The deployment also fits AT&T’s stated Open RAN direction. In 2023, AT&T said it intended for 70% of its wireless traffic to flow over open-capable platforms by late 2026, with Ericsson among the suppliers supporting its modernization path. The 600 MHz deployment itself should not be conflated with an Open RAN announcement, but it will take place within a RAN estate being progressively modernized for greater openness and flexibility.

What to Watch Next:

The immediate question is deployment execution. AT&T has not yet released commercial launch dates, market sequencing, site counts, or device-support details for its new 600 MHz spectrum. Those disclosures will determine whether this is primarily a targeted coverage investment, a broad nationwide low-band overlay, or a phased modernization program extending over several years.lightreading+1

The more substantive test will be whether AT&T can translate a high-value spectrum acquisition into measurable improvements in rural availability, indoor coverage, cell-edge performance, and uplink experience. The Ericsson selection is the necessary first step: it turns an underutilized spectrum asset into a deployable radio-network program. The ultimate value will come from execution at scale.

Addendum- “8RX” Explained:

In this AT&T/Ericsson deployment, 8RX means eight radio-frequency receive chains at the network side. The handset still transmits its normal uplink signal; the cell site has more antenna/receiver observations from which to recover it.

This differs from 8RX in a handset or fixed-wireless terminal, where it generally improves the device’s downlink reception. Here, the direction is reversed: the base station’s added receive capability benefits device-to-network traffic.

Uplink mechanisms:

Diversity gain: The eight branches experience somewhat different fading and multipath conditions. Combining them makes it less likely that a deep fade on one path causes decoding failure.
Array/combining gain: When receive paths can be coherently combined, the desired UE signal arrives with a stronger effective signal-to-noise-plus-interference ratio. In an idealized case, doubling the number of equivalent receive branches from four to eight can provide roughly 3 dB of additional combining gain, though the field result depends on antenna correlation, propagation, and implementation.
Interference suppression: More antenna observations give the receiver more spatial degrees of freedom to distinguish a desired UE from co-channel interferers. This can improve uplink SINR and allow more robust—or, when conditions permit, higher-order—uplink modulation and coding.
Better cell-edge operation: The uplink is often the limiting direction in wide-area low-band coverage because UE transmit power is tightly constrained. Improving the base-station receiver makes a low-power device more likely to maintain service from a building, rural location, or cell edge.

Why it is significant at 600 MHz:

600 MHz’s principal advantage is coverage: it propagates farther and penetrates buildings more effectively than higher-frequency spectrum. But broad downlink coverage can expose an uplink asymmetry—the device may receive the cell reliably yet lack sufficient transmit power for an equally strong return path.

8RX specifically addresses that asymmetry. AT&T says its Ericsson radios will enable uplink-enhancing 8RX across low bands for the first time, while Light Reading notes that low-band FDD networks such as 600 MHz have typically used 4RX radios and that 8RX had been relatively uncommon below 1 GHz.

Conceptually, with $N$ receive branches, the base station adheres to this equation:

Starlink Mobile: NTN–Terrestrial Convergence, Network Capacity, and the Limits of Disruption

Posted on August 8, 2026 by Alan Weissberger

Executive Summary:

Elon Musk’s strategic objective for Starlink extends beyond satellite broadband connectivity for remote, maritime, aviation, and enterprise users. SpaceX is positioning Starlink for a broader role in mobile communications through an integrated non-terrestrial network (NTN) and terrestrial-network architecture. That strategy could combine direct-to-device (D2D) satellite connectivity, satellite backhaul, selected terrestrial access infrastructure, and potentially a retail mobile service.

Financial markets have treated that prospect seriously. Shares of U.S. wireless network operators have been under pressure since SpaceX President Gwynne Shotwell described the opportunity for “Starlink Mobile” as “huge,” in a CNBC interview on June 12th. On SpaceX’s recent earnings call, Shotwell characterized the U.S. wireless market as generating $600 billion in annual revenue and stated, “and I anticipate us to be able to acquire quite a few of their customers because I think our service will be better.”

Editor’s Note: The combined annual revenue of AT&T, Verizon, and T-Mobile is closer to $360 billion, depending on the reporting period and whether total revenue or service revenue is used.

The timing, service architecture, spectrum strategy, device ecosystem, and go-to-market model for a SpaceX mobile offering remain unresolved. A central distinction is needed: direct-to-device NTN service, satellite backhaul, a terrestrial radio access network (RAN), and a consumer mobile service are related but technically and commercially distinct propositions.

The most plausible medium-term outcome is not wholesale replacement of U.S. mobile network operators (MNOs), but deeper NTN–terrestrial integration. LEO satellite systems can extend coverage, improve resilience, support mobility, and connect underserved areas. Dense terrestrial networks retain structural advantages for high-traffic urban service, indoor coverage, and busy-hour mobile capacity.

“The perceived risk of Starlink Mobile disrupting the U.S. wireless industry is greater than the actual risk in the next one to two years,” says Morgan Stanley analyst Sean Diffley.

Starlink’s satellite-broadband business serves 12 million subscribers and reportedly generates profit margins above 60%. Musk’s ambitions, however, extend beyond connectivity for aircraft, ships, and remote fixed locations. SpaceX plans a large third-generation Starlink constellation, supported by the anticipated launch economics of its fully reusable Starship system. Starlink V3 satellites are expected to materially increase satellite capacity relative to earlier generations.

However, aggregate constellation capacity should not be equated with mobile-network capacity in dense urban markets. The relevant question is how much spectrum, beam capacity, spatial reuse, and backhaul capacity can be delivered to a given area during the busy hour.

…………………………………………………………………………………………………………………………………………………

Starlink Mobile could develop along four, potentially overlapping, paths:

Service or architecture	Primary function	Principal constraint
Direct-to-device NTN	Extends basic connectivity beyond terrestrial coverage using standard or adapted mobile devices	Limited shared spectrum and capacity over large beam footprints
Satellite backhaul	Connects selected remote, temporary, or difficult-to-fiber terrestrial sites	Cost, capacity, availability, and traffic concentration
Hybrid NTN–terrestrial network	Combines satellite coverage extension with targeted terrestrial RAN deployment	Capital intensity and operational integration
Retail mobile service or MVNO	Markets consumer service using wholesale terrestrial access and Starlink capabilities	Dependence on partner economics and network-control limitations

The proposed Starlink Mobile service should therefore be assessed as an integrated network proposition, not as a simple satellite replacement for a nationwide cellular network.

Why Terrestrial Networks Retain an Advantage:

The central technical constraint is spatial/spectrum reuse. Terrestrial mobile networks deliver high area capacity by repeatedly reusing licensed spectrum across dense grids of macro cells, small cells, and indoor systems. Capacity is further increased through sectorization, advanced antenna systems, massive MIMO, carrier aggregation, and high-capacity fiber or microwave backhaul.

A LEO satellite system has different strengths. It can provide wide-area reach, support mobility, offer resilience during terrestrial outages, and extend coverage to regions where conventional network deployment is uneconomic. Yet its radio resources are shared across comparatively large beam footprints. This creates more demanding link-budget, capacity, and spectral-efficiency constraints in high-density areas, particularly for indoor service and busy-hour traffic.

Terrestrial-cell coverage areas vary considerably with spectrum band, terrain, urban morphology, antenna configuration, and load. Nevertheless, the architectural distinction remains: terrestrial networks achieve high capacity by spatially reusing spectrum over relatively small geographic areas, whereas satellite systems must manage shared capacity over much broader footprints.

For this reason, Starlink V3 satellites may substantially improve overall system capability without eliminating the terrestrial RAN advantage in dense urban and suburban markets. The strongest near-term use cases for NTN are likely to include coverage extension, emergency communications, maritime and aviation connectivity, mobility, IoT, selected backhaul, and service in remote or underserved locations.

3GPP’s NTN work is specifically directed toward integration with terrestrial cellular and wireline networks, reinforcing the view that NTN will develop as part of a broader communications architecture rather than wholly separate from it. Analyss opinions:

Daiwa Capital Markets analyst Jonathan Kees similarly argues that Starlink is “only a complement, not a substitute” for existing wireless infrastructure.
BofA Securities analyst Michael Funk reaches a comparable conclusion: “Existing direct-to-device satellite technology [is] underdeveloped and largely complementary to terrestrial mobile networks,” Funk says.

Spectrum, Capital, and AI:

SpaceX has acquired valuable spectrum assets through its EchoStar transactions. The FCC approved the transfer of approximately 65 MHz of spectrum to SpaceX for next-generation direct-to-device use. This is strategically important, but spectrum ownership alone does not establish a nationwide facilities-based mobile network.

A fourth nationwide MNO would require much more than spectrum. It would require:

Radio-access infrastructure, including macro sites, small cells, antennas, radios, and power.
High-capacity backhaul and transport networks.
Mobile core-network functions, service assurance, cybersecurity, and operational-support systems.
Device testing and certification, distribution, retail channels, billing, customer care, and subscriber-acquisition spending.
Sustained capital investment to expand coverage and capacity as traffic grows.

SpaceX must also finance Starlink V3 production, launches, constellation replenishment, gateways, ground infrastructure, and continuing development of D2D and NTN capabilities. At the same time, the company is investing heavily in AI infrastructure and Starship. Reported second-quarter capex exceeded $18 billion, including approximately $15.83 billion associated with AI infrastructure.

This does not establish that SpaceX lacks the financial capability to enter mobile communications. It does establish a major capital-allocation challenge. AI infrastructure requires rapid, front-loaded investment; terrestrial mobile networks require multi-year and geographically distributed deployment; and satellite systems require recurring capital expenditure for replenishment and capacity expansion.

—->Please see detailed discussion of this issue in Addendum below Conclusions subhead.

The key strategic risk is therefore prioritization. If AI, Starship, and satellite-constellation investment continue to absorb the majority of incremental capital, Starlink Mobile may progress more slowly as an independent terrestrial build. It may instead favor targeted terrestrial deployment, satellite-enabled backhaul, wholesale arrangements, or an MVNO model.

Starlink Coverage Issues as per Iain Morris of Light Reading:

Starlink is estimated to have between 3 and 4 million subscribers in the U.S., mostly in rural areas where there is no fixed or mobile alternative. That is, after all, why someone would opt for satellite broadband. But a small cell network built on the rooftops of these 3 to 4 million customers – or several times that amount – is not going to provide the mobile coverage demanded by anyone who even occasionally travels a few miles from home. And inside the building, what advantage would a Starlink cellular service have over Starlink-supported Wi-Fi?

SpaceX cannot possibly hope to address this coverage problem without some kind of physics-defying technological breakthrough. According to figures shared by an authoritative source on the telco side, a small cell might get you coverage about half a kilometer from the basestation, while a rural macro site would take you up to 20 kilometers from it. In urban areas where higher-frequency spectrum comes into play, this radius would probably fall to about 2 kilometers, making small cells look more competitive. The trouble there is Starlink’s lack of subscribers in cities.

Other estimates do not improve the outlook. William Webb, an academic and analyst who previously worked for UK telecom regulator Ofcom, thinks Starlink might be able to achieve a coverage radius of 1 to 2 kilometers with roof-mounted antennas, “assuming a reasonably high gain cellular antenna is integrated into the Starlink terminal and oriented correctly,” as he wrote in a LinkedIn update. But mounting below roof level would reduce the figure to less than 1 kilometer, according to Webb.

“The biggest issue will likely be that overall coverage will be patchy, concentrated in areas where there are the most Starlink broadband subscribers,” he said. “These are likely to be rural areas where fixed broadband provision is poor. As a result, coverage will likely be overlapping in rural communities but sparse outside of these areas.”

Commercial Models and Possible Partnerships:

SpaceX may determine that a fully independent nationwide mobile network is not the most efficient near-term approach. An MVNO arrangement would allow SpaceX to purchase terrestrial capacity at wholesale rates while offering a consumer service incorporating Starlink capabilities. Such a model could provide near-national coverage more rapidly, though it would reduce SpaceX’s control over network economics, service differentiation, and quality-of-service management.

Several Starlink Mobile outcomes are plausible:

Path	Capital requirement	Likely implication
Independent nationwide MNO	Very high	Long deployment cycle, substantial execution risk, and intense capital competition with AI, Starship, and satellite programs
Hybrid NTN–terrestrial network	High, but targeted	Satellite supports coverage extension and selected backhaul; terrestrial infrastructure is concentrated where capacity demand is greatest
MVNO or strategic MNO partnership	Lower upfront capex	Faster national-market entry, but less control over margins, network policy, and customer experience

Why would AT&T, Verizon, or T-Mobile enter an MVNO or deeper partnership with a prospective competitor? The answer may be competitive strategy. The first MNO to secure a commercially favorable relationship with SpaceX could gain a relative advantage in coverage, satellite integration, customer acquisition, or enterprise services.

SpaceX is “going to have to partner with one of the mobile network operators like a Verizon or T-Mobile,” says RBC Capital Markets analyst Ken Herbert. “They’re going to have to find ways to work with other companies.”

T-Mobile already has a direct-to-cell/device (D2D) relationship with SpaceX. Verizon’s FWA business is more directly exposed to fixed-broadband competition from Starlink, while AT&T, Verizon, and T-Mobile each possess extensive spectrum, RAN, transport, and customer-service assets that would be difficult and costly for a new nationwide entrant to replicate.

Evaluating Starlink/Spacex Deployment Plans:

Starlink’s satellite-broadband business serves 12 million subscribers and reportedly generates profit margins above 60%. Musk’s ambition, however, is substantially broader than providing internet access to aircraft and oceangoing vessels. SpaceX plans to deploy as many as 100,000 third-generation Starlink satellites, supported by the anticipated economics of its fully reusable Starship launch system. Starship remains in the test phase, but SpaceX has stated that it is designed to place up to 150 metric tons in orbit per launch at approximately one-tenth the per-kilogram cost of Falcon 9. Starlink V3 satellites are expected to provide roughly 10 times the capacity of earlier-generation spacecraft.

SpaceX is advancing these plans at a time when the U.S. communications market is already experiencing cross-sector competitive convergence. Fifth-generation mobile technology enabled MNOs to expand fixed wireless access (FWA) offerings and compete more directly with cable operators for residential broadband customers. The resulting service bundles combine mobile subscriptions, home broadband, and, in some cases, video and value-added services. Cable operators, in turn, have expanded mobile offerings, generally using Wi-Fi offload, their extensive wireline footprints, and mobile virtual network operator (MVNO) arrangements with incumbent wireless carriers for wide-area cellular coverage.

This competitive equilibrium has modestly favored wireless operators, although neither sector has emerged unambiguously dominant. AT&T, for example, is expected to generate sales and earnings growth over the next several years, albeit below broader market growth rates. Comcast faces a more constrained outlook, with relatively flat expected revenue and earnings performance. The valuation gap reflects both differing growth expectations and the capital intensity of maintaining and upgrading nationwide communications infrastructure.

Wall Street has amplified concerns about SpaceX’s competitive impact. Early research coverage has broadly characterized the launch, satellite-connectivity, and artificial-intelligence company as a disruptive force. The average analyst price target for SpaceX stock is approximately $227, implying a valuation near $3 trillion—roughly five times the combined market capitalization of AT&T, Verizon, and T-Mobile.

The major U.S. MNOs also operate with substantial debt burdens. AT&T, Verizon, and T-Mobile collectively carry approximately $420 billion in net debt, against about $140 billion in expected 2026 EBITDA. “I would not for a second sleep easily if I had the investments that [wireless telecom providers] have, and the debt that they have, and Elon Musk working on a superweapon as it pertains to my business,” says Drew Cupps of Polen Capital.

Nevertheless, Starlink faces significant capital, engineering, and deployment challenges before it can offer a broadly substitutable mobile service. Daiwa Capital Markets analyst Jonathan Kees argues that the investment required to build a V3-based Starlink constellation capable of materially disrupting terrestrial operators is underestimated. He estimates that constellation deployment could require more than $100 billion, excluding investment associated with SpaceX’s AI initiatives. Starlink is “only a complement, not a substitute” for existing wireless infrastructure, says Kees.

The fundamental constraint is spatial reuse and capacity density. A terrestrial cell site can concentrate spectrum resources over a coverage area measured in a few square miles, while a LEO satellite beam may serve a much broader footprint. Satellite systems therefore face more difficult link-budget, capacity, and spectral-efficiency challenges in dense urban environments, particularly for indoor service and high-traffic applications. V3 satellites may substantially improve system capacity, but they do not eliminate the capacity advantage of dense terrestrial RAN deployments.

For that reason, BofA Securities analyst Michael Funk does not view SpaceX as an immediate, large-scale competitive threat to incumbent MNOs. While some projections assign LEO-based mobile services 15% to 35% of the U.S. telecommunications market, Funk regards those estimates as overly optimistic. “Existing direct-to-device satellite technology [is] underdeveloped and largely complementary to terrestrial mobile networks,” Funk says. That assessment is consistent with Starlink’s present international model, which emphasizes partnerships with mobile operators rather than wholesale replacement of their networks.

Conclusions:

Starlink Mobile is an important strategic development in the evolution of NTN–terrestrial convergence. It should not, however, be evaluated as a satellite-only replacement for nationwide cellular networks.

LEO systems can provide broad-area reach, coverage extension, resilience, mobility, selected backhaul, and direct-to-device services. Dense terrestrial RAN infrastructure retains decisive advantages in spatial reuse, indoor coverage, spectrum utilization, and busy-hour capacity. Starlink’s most credible competitive impact in the near and medium term is therefore likely to occur in selected coverage, mobility, resilience, backhaul, and fixed-broadband segments—not through immediate replacement of nationwide terrestrial mobile networks.

The central uncertainty is which architecture and commercial model SpaceX will adopt. Its concurrent commitments to AI infrastructure, Starship, satellite replenishment, and spectrum assets may favor a hybrid or partnership-led approach over a fully independent nationwide MNO build.

In that outcome, incumbent operators’ spectrum, terrestrial RAN, fiber backhaul, tower infrastructure, customer relationships, and regulatory authorizations remain strategically important. Rather than becoming obsolete, those assets may increase in value as NTN and terrestrial networks become more tightly integrated.

If satellite and terrestrial systems become increasingly interdependent, incumbent operators’ assets may become more valuable rather than less. Spectrum, fiber backhaul, tower infrastructure, distributed RAN assets, customer relationships, billing systems, and regulatory authorizations remain essential elements of an integrated non-terrestrial network (NTN) and terrestrial-network ecosystem. EchoStar’s share-price appreciation over the past year illustrates the strategic value that spectrum holdings can command, particularly as SpaceX and AT&T acquire additional spectrum assets.

The three national U.S. wireless operators collectively hold spectrum assets estimated to be worth more than $400 billion based on recent transaction benchmarks. That figure is approximately 80% of their combined market capitalization and is broadly comparable to their aggregate debt burden. Spectrum holdings alone do not establish an investment thesis, but they provide a meaningful asset-value foundation as satellite, terrestrial, and hybrid connectivity models continue to evolve. They aren’t going to sell their spectrum. They have businesses to run, and those businesses are reasonably valued and growing.

Addendum: AI Capex is a Significant Risk for Starlink Mobile:

AI-data-center investment is a significant capital-allocation risk to Starlink Mobile, but it is not, by itself, evidence that SpaceX lacks the financial capacity to enter mobile communications. The more credible concern is that AI, Starship, constellation replenishment, and terrestrial mobile deployment will compete for capital simultaneously—potentially slowing Starlink Mobile’s rollout, limiting network densification, or increasing reliance on an MVNO partnership.

SpaceX’s capital spending has risen sharply: reported second-quarter capex exceeded $18 billion, including approximately $15.83 billion directed to AI infrastructure. Management indicated that similarly elevated capex could continue over subsequent quarters. Meanwhile, Starlink profitability and connectivity operations remain an important source of funding for the broader AI strategy.

A facilities-based mobile network would add another exceptionally capital-intensive program:

SpaceX has already committed approximately $19.6 billion through its EchoStar spectrum transactions for up to 65 MHz of spectrum, including associated debt obligations. Thus, the issue is not whether it can acquire any spectrum; it has already done so. The issue is whether that spectrum portfolio is sufficient for a competitive nationwide terrestrial-mobile network, particularly in high-density markets.reuters
A fourth nationwide MNO requires far more than spectrum: site acquisition, radios, antennas, power, backhaul, core-network functions, device certification, retail/distribution, customer care, and sustained subscriber-acquisition spending.
Starlink must also fund V3 satellite production, launch capacity, gateway infrastructure, constellation replenishment, and the evolution of direct-to-device/non-terrestrial-network capabilities.

These programs have distinctly different investment horizons. AI infrastructure requires rapid, front-loaded spending to secure compute capacity; terrestrial mobile networks require multi-year, geographically distributed capex; and satellite systems require continuous capital expenditure to maintain and upgrade orbital capacity.

The likely consequence is not cancellation of Starlink Mobile, but a more capital-disciplined architecture than a conventional nationwide greenfield MNO build. SpaceX has said it intends to build terrestrial mobile services but has not disclosed projected mobile capex or a site-count plan; analysts have warned that a competitive direct-to-consumer national offering would be very difficult without an MVNO agreement providing broad baseline coverage. This produces three plausible outcomes:

Path	Capital requirement	Likely implication
Independent nationwide MNO	Very high	Slow rollout, large execution risk, and a potentially prolonged cash drain while AI and Starship also consume capital
Hybrid satellite–terrestrial network	High but more targeted	Terrestrial build concentrated in capacity-constrained urban and suburban areas; Starlink provides backhaul, coverage extension, and resilience
MVNO or strategic MNO partnership	Lower upfront capex	Fastest route to nationwide service, but less control over margins, product design, and differentiation

Technical constraint remains decisive: Even if SpaceX could fully finance a terrestrial build, capital alone does not eliminate the fundamental network-engineering constraints. Its acquired spectrum is valuable, but incumbents have substantially deeper spectrum portfolios, dense existing cell-site grids, mature indoor-coverage solutions, established device ecosystems, and decades of operational experience.

Satellite connectivity can reduce backhaul requirements at selected sites and enhance rural, maritime, aviation, emergency, and resilience use cases. It cannot economically substitute for dense terrestrial spectral reuse in the highest-traffic urban areas. Therefore, AI-related capex pressure is particularly relevant because Starlink Mobile needs substantial investment precisely where the satellite component provides the least complete replacement for terrestrial infrastructure.

A key additional risk is strategic prioritization, not immediate insolvency. If SpaceX continues allocating the overwhelming share of incremental capital to AI data centers and Starship, Starlink Mobile may emerge as a hybrid service, wholesale platform, or MVNO-enabled offering rather than a fully independent fourth nationwide carrier. That outcome would reduce the near- to medium-term disruption risk to AT&T, T-Mobile, and Verizon. It would also reinforce the more technically credible view that Starlink is likely to be complementary to terrestrial mobile networks for years, even if it becomes a powerful competitor in selected coverage, backhaul, and mobility segments.

Eutelsat hails EC’s IRIS-2 project to take on U.S. NTN providers

Posted on August 7, 2026 by Alan Weissberger

Executive Summary:

The European Commission (EC) has announced the next steps for the IRIS²[1.] project after reaching an implementation agreement with the prime contractors, one of which is Eutelsat. The EC agreed terms with the SpaceRISE consortium – comprising Eutelsat, Hispasat and SES – for deploying the satellite system, which includes adding 66 more low-Earth orbit (LEO) satellites dedicated to defense, security and emergency services, and launching services from 2029.

Note 1. IRIS² Backgrounder:

IRIS² is the European Union’s secure-connectivity LEO satellite program: Infrastructure for Resilience, Interconnectivity and Security by Satellite. It is intended to provide sovereign, resilient communications for EU governmental users while also supporting commercial broadband and connectivity in underserved areas. IRIS² is planned as a multi-orbit constellation of 290 satellites, principally in low-Earth orbit (LEO) and medium-Earth orbit (MEO). Combining LEO’s lower latency with MEO’s wider coverage is meant to support secure, high-availability communications across Europe and beyond.

IRIS² was established under Regulation (EU) 2023/588, the Union Secure Connectivity Programme for 2023–2027. The Commission awarded a 12-year concession in December 2024 to the SpaceRISE consortium—SES, Eutelsat, and Hispasat—with major European aerospace, satellite, and telecom companies participating as subcontractors.

The current planning cited by ESA anticipates first satellite launches in 2029, initial services in 2030, and full operations targeted for 2031. In the interim, initial governmental capability is to draw on pooled national satellite resources through GOVSATCOM.

IRIS² is commonly described as the EU’s third flagship space program after Galileo and Copernicus. Its strategic rationale is European digital and communications sovereignty: reducing reliance on non-European satellite systems, improving resilience against cyber and physical disruptions, and sustaining a European space/telecom industrial base. It is not simply a European retail satellite-internet competitor to Starlink; secure governmental connectivity and strategic autonomy are central design objectives.

A good part of the motivation to build the IRIS²satellite system is to reduce reliance on U.S. satellites internet providers (e.g. Starlink, Amazon LEO), especially for sensitive military and government communications.

Principal uses of IRIS²include:

Secure communications for EU institutions, Member States, defence/security users, embassies, and critical infrastructure.
Crisis management, disaster/humanitarian response, border or surveillance-related applications.
Broadband, transport connectivity, satellite trunking, and service in terrestrial coverage gaps.
Integration with 5G/non-terrestrial-network technology; the Commission’s 2026 terminal-industrialization call explicitly includes 5G NR NTN-compliant modem/baseband capabilities.

……………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………

Eutelsat CEO Jean-François Fallacher said this is “a very important milestone” that moves the project on from design and preparation to an “operational phase” and confirms Eutelsat’s role as the program’s “LEO lead.” Fallacher shared a high-level view of some of the system’s new technology that is hoped to give it an advantage over larger U.S. rivals. He said the multi-orbit MEO-LEO constellation is “very advanced,” and will have “much more” capacity than satellite internet provider OneWeb has today.

He also confirmed it will be based on 5G non-terrestrial network (NTN) standards, which is “important.”

“We use 5G NTN technology. For IRIS², we want to normalize the technology … This is also a way to fight against the American giants because today each of the technology used by ourselves on OneWeb (now owned by Eutelsat), by Amazon or by Starlink are full proprietary technologies,” he said. “Going to normalized technologies such as 5G NTN will also help [in] bringing the cost down [and] having antennas which will be cheaper and of a smaller size.”

Eutelsat, which also operates 31 geostationary orbit (GEO) satellites, gained its LEO constellation with the acquisition of OneWeb in 2023. It is a distant second LEO operator with around 650 satellites, compared to Starlink’s more than 10,000. They both operate LEO constellations, but Eutelsat has a “fundamentally different constellation with different target customers, business models and scale.” LEO connectivity accounted for 25% of Eutelsat’s total revenue of €1.23 billion (US$1.41 billion) for the fiscal year ending June 30, and LEO revenue grew 70% year-over-year.

For IRIS², Eutelsat will design and operate 264 dual Mil-Ka/Ku band and 66 Mil-Ka band satellites. The company said it will invest €2.23 billion ($2.57 billion) in the shared infrastructure and €1.16 billion ($1.34 billion) in the commercial infrastructure (which includes Ku payload and commercial ground equipment), with spending phased from 2027 to 2034. According to its concession agreement with the EC, the company said it expects revenue from IRIS²activity to be more than €10 billion ($11.6 billion) from 2032 to 2040. The Ka-only satellites are planned to start launching in 2029, while the commercial Ku LEO system is expected to be operational by mid-2032. Eutelsat also said it plans to add 229 satellites to OneWeb through 2034 in addition to 440 new first-generation satellites for an investment of €1 billion ($1.2 billion).

IRIS² links EU spectrum policy to sovereign satellite connectivity:

The EC’s proposed allocation of the 2 GHz mobile-satellite-services band complements IRIS², the EU’s secure-connectivity program. One-third of the spectrum would be assigned to a European operator providing governmental services—security, critical communications, and defense—with a requirement to integrate with present and future IRIS² capabilities. Together, the initiatives seek to strengthen Europe-controlled satellite infrastructure and reduce reliance on non-European systems.

IRIS² is designed primarily for secure governmental connectivity, including defense, crisis response, civil protection, and critical-infrastructure users. The SpaceRISE concession—led by Eutelsat, SES, and Hispasat—also permits commercial use of shared infrastructure. The planned multi-orbit architecture combines LEO and MEO satellites to provide resilience, coverage, and broadband capacity.

3GPP 5G NR-NTN alignment:

IRIS² is intended to use 3GPP 5G NR non-terrestrial-network (NTN) technology in the space, ground, and user-terminal segments. At the March 2025 3GPP RAN#107 plenary, industry participants described IRIS² as a multi-orbit Ku-/Ka-band broadband constellation adopting 5G NR-NTN specifications; the expected benefits are interoperability with terrestrial mobile networks, multi-vendor terminal support, and a broader equipment ecosystem.

The relevant 3GPP baseline NTN specs include:

Release 17 NR-NTN, which introduced foundational 5G NR satellite support, including architecture and radio adaptations for long propagation delay, Doppler shift, satellite ephemeris/UE location assistance, timing advance, and HARQ operation. The principal study and solutions specifications are 3GPP TR 38.811 and TR 38.821.
3GPP TS 38.300, the NR overall-description specification, which defines NTN architectural support; TS 38.331, which specifies RRC signaling needed for NTN-related configuration and assistance information.
3GPP TS 38.101-5, which defines NR user-equipment RF requirements for satellite/NTN operation. For Ka-band VSAT-type terminals, this includes NTN bands such as n510, n511, and n512, with downlink spectrum in the 17.7–20.2 GHz range and uplink spectrum extending into the 27.5–30 GHz range, depending on band.
Release 18 5G-Advanced NTN enhancements, including further NR-NTN performance and mobility enhancements, as well as expanded satellite spectrum support. Release 18 added NTN band n254 alongside the Release 17 n255 and n256 L-/S-band options.

3GPP Release 19 gives IRIS² a more capable 5G-Advanced NTN standards baseline, but it does not redefine the programme’s core sovereign-connectivity mission or its already-selected multi-orbit architecture. Its practical role is to enable a more interoperable evolution of IRIS² user terminals, gateways, and potentially onboard processing as the constellation is deployed from 2029 onward. Release 19 was frozen in 2026, making it a stable implementation target rather than only a work-in-progress specification.

For IRIS², the most relevant Release 19 NTN enhancements are:

Regenerative-payload support. Release 19 supports an NTN architecture in which a complete 5G gNB may be hosted onboard a satellite, rather than using only a transparent bent-pipe payload. This can reduce dependence on feeder-link and gateway availability, improve latency for certain paths, and enable more flexible routing and service continuity—important attributes for resilient governmental communications.
NR-NTN Phase 3 enhancements. These build on the Release 17 and 18 foundations for NR satellite access, addressing NTN mobility, access, capacity, and performance issues associated with high Doppler, long propagation delay, and fast-moving LEO satellites.
GNSS-independent operation and positioning. Release 19 work includes support for UE access when GNSS is unavailable, as well as positioning enhancements for satellite-only access. Those capabilities have clear relevance for emergency, defence, and resilience use cases where GNSS availability may be degraded, denied, or unreliable.
Enhanced IoT NTN. Release 19 adds store-and-forward operation, IoT-NTN TDD capability, public-warning support, and uplink-capacity improvements. These can support lower-power, delay-tolerant sensing and asset-monitoring applications across critical infrastructure, transport, energy, and remote areas.
Additional NTN spectrum support. Release 19 expands the 3GPP NR-NTN band portfolio, including Ku-band-related work and additional S- and L-band options. This is relevant to the evolution of IRIS² terminals and complementary mobile-satellite services, although the IRIS² broadband layers principally use Ku and military Ka-band spectrum.

IRIS² can use Release 19 to move beyond basic satellite backhaul or proprietary broadband toward a standards-based 5G NTN platform with greater integration into terrestrial 5G networks. Standardization should support multi-vendor terminals, common modem and protocol ecosystems, roaming/interworking possibilities, and a less proprietary ground-segment architecture.

IRIS² has publicly committed to adoption of the 3GPP 5G NR-NTN specification family, but the precise release profile and the definitive set of normative TS requirements for each satellite, gateway, and terminal have not yet been publicly detailed. It would therefore be more accurate to describe the programme as 3GPP 5G NR-NTN-aligned than to assert blanket compliance with every specification or band.

Competitive and regulatory context:

The initiative has drawn U.S. regulatory attention. FCC Chairman Brendan Carr suggested that European restrictions on U.S. satellite operators could invite reciprocal treatment in the United States, while SpaceX has reportedly asked the FCC to examine Eutelsat’s planned constellation expansion.

Luke Pearce of FDM CCS Insight said that Starlink’s use in Ukraine illustrates why the EU seeks a non-U.S.-dependent secure-connectivity capability:

“Ukraine’s use of Starlink on the front line has highlighted how important satellite communications will be in future warfare. The EU is understandably keen not to be reliant on its US partners for this capability.”

Pearce doubts the project can catch up to Starlink, or even Amazon’s planned rollout. IRIS²has been “marred by significant uncertainty and scrutiny” since it was announced in November 2022, and “at times, the project has appeared destined to fail,” he said. Initial services were supposed to launch in 2024. Now, the full system is likely to arrive in 2030 or later, he explained.

“It is therefore materially behind Starlink and will almost certainly remain so. By the time IRIS² is operational, SpaceX will have moved through further generations of satellites, terminals and services. Amazon Leo will also be a much more established competitor. Using standardized technology should broaden the equipment ecosystem, improve interoperability with terrestrial networks and ultimately bring costs down. However, 5G NTN is not a silver bullet. Standardization alone will not overcome the US’s enormous lead in satellite manufacturing, launch capabilities, terminals and overall scale,” said Pearce.

Conclusions:

IRIS² is materially behind Starlink in deployed constellation scale, launch capacity, terminals, and service maturity. Standardized 5G NR-NTN can improve interoperability and reduce ecosystem fragmentation, but it cannot independently offset those scale advantages. IRIS² should therefore be assessed chiefly as a European sovereign-connectivity and resilience program, rather than as a like-for-like retail broadband challenger to Starlink or Amazon Leo.

3GPP Release 19 provides an important 5G-Advanced NTN evolution path for IRIS². In addition to Release 17/18 NR-NTN baseline capabilities, Release 19 introduces support for regenerative satellite payloads, enhanced LEO mobility and access procedures, GNSS-independent operation, improved positioning, and expanded IoT-NTN functions including store-and-forward delivery. These features could improve the resilience, interoperability, and terrestrial-network integration of later IRIS² system increments.

The applicable ITU-R NTN satellite Recommendation is currently ITU-R M.2177-0 (February 2026), Detailed specifications of the satellite radio interfaces of IMT-2020. It identifies the “3GPP 5G-NTN: RIT” and “3GPP 5G-NTN: SRIT” as the IMT-2020 satellite radio interfaces. The Recommendation explicitly covers NR-NTN and IoT-NTN and points to 3GPP global core specifications rather than reproducing the full 3GPP technical corpus.

Optus and Nokia’s pre-“6G” Trial in Australia: Upper 6 GHz May Be Widely Deployable

Posted on August 5, 2026 by Alan Weissberger

Executive Summary:

Australia’s Optus and Nokia have delivered one of the more credible pre 6G demonstrations yet: a live-field trial in Sydney that paired multi-gigabit speed with good coverage. The most notable result was the 3.5 Gbps peak download rate and the indication that upper 6 GHz could support a macrocell footprint comparable to today’s 5G 3.5 GHz network. The trial suggested the upper 6GHz band can cover roughly the same footprint as Optus’ existing 5G 3.5 GHz layer—an encouraging sign for lower-cost 6G upgrades.

TABLE 1. Optus–Nokia 6G Trial: Editorial Comparison of Technical Takeaways
(Adapted from reported trial results.)

Attribute	Reported trial result	Editorial significance
Location	Sydney, Australia.	Places the trial in a live urban macro-network environment, not a controlled lab.
Participants	Optus and Nokia.	Combines operator network context with vendor radio expertise.
Spectrum band	Upper 6 GHz.	Reinforces the growing view that 6–8 GHz is a strong candidate range for 6G coverage and capacity. ericsson+1
Spectrum width	200 MHz total, split into two 100 MHz channels.	Provides enough bandwidth to demonstrate multi-gigabit throughput without relying on mmWave-style densification.
Frequency range	6,890 MHz to 7,090 MHz.	Falls squarely in the upper 6 GHz segment being discussed globally for future mobile use.
Peak downlink speed	3.5 Gbps.	A smartphone-form-factor speed record for this part of the band, but more important as a proof point for practical mobility.

Why this trial stands out:

In early 6G discussions, spectrum, coverage, and deployment economics are inseparable. Higher-frequency bands can offer more capacity, but they often demand denser networks and new site builds; that is precisely why the Sydney result matters.ericsson+1

Optus and Nokia’s trial suggests upper 6 GHz may offer a useful compromise: enough bandwidth for high throughput, yet enough propagation performance—when paired with advanced antenna techniques—to preserve broad-area coverage on existing infrastructure.telconews.com+1

What was tested:

According to the reported trial details, the teams used 200 MHz of upper 6 GHz spectrum, divided into two 100 MHz channels between 6,890 MHz and 7,090 MHz. Nokia’s proof-of-concept AirScale massive MIMO active antenna unit used 768 antenna elements and 128 transceiver chains at an existing Optus site operating alongside a live 5G network.telconews.com+1

That setup matters because it moves the conversation beyond lab conditions. A field trial on a live site is a better indicator of how upper 6 GHz may behave in real deployments, where interference, propagation, and network integration all shape performance.telconews.com+1

The bigger 6G implication:

The strongest signal from the trial is economic, not just technical. If operators can use upper 6 GHz with existing towers and familiar radio footprints, they may be able to introduce early 6G services without rebuilding their networks from scratch.telconews.com+1

That would be a major shift in how the industry thinks about 6G rollout. Instead of requiring an entirely new layer of dense infrastructure, upper 6 GHz could become a practical evolution path from 5G to 6G, especially for operators seeking capacity gains without a full civil-engineering reset.nokia+1

Spectrum policy:

This trial also lands in the middle of a broader spectrum-policy debate. The upper 6 GHz band is widely viewed as strategically important for future mobile networks, and results like this strengthen the case for allocating at least part of the band to licensed mobile use.ericsson+1

At the same time, the band remains attractive for other services, including unlicensed use cases. The Sydney trial does not settle that debate, but it does provide real-world evidence that upper 6 GHz is not merely theoretical: it can deliver both range and capacity under conditions that resemble operational deployment.

Quotes:

According to Sri Amirthalingam, Optus Chief Technology Officer, the achievement forms part of Optus’ ongoing network innovation program and its long-term work to help shape the technologies, standards and spectrum frameworks that will underpin the evolution from 5G to 6G.

“This trial is an important milestone in Optus’ long-term 6G research program and helps us better understand how future mobile networks can be designed to meet Australia’s unique connectivity needs. Achieving 3.5Gbps using upper 6GHz spectrum demonstrates the significant opportunity this band could provide for future networks as demand for data-intensive applications such as AI services, immersive video, cloud applications and connected devices continues to grow.

“As networks become increasingly AI-native, that enhanced capability will unlock a new generation of AI-powered experiences, from smarter digital assistants that can understand their environment, to more immersive education and real-time support for frontline workers. Our focus is on turning these innovations into meaningful benefits for Australians,” he added.

Mark Atkinson, Head of Radio Networks, Mobile Infrastructure at Nokia, says, “This trial with Optus demonstrates the potential of upper 6GHz spectrum to deliver the high capacity and performance that future networks will require, while also validating how existing infrastructure can evolve towards 6G.

“At Nokia, we see AI and connectivity becoming increasingly intertwined, with AI-native networks and AI-RAN enabling operators to deliver greater efficiency, better customer experiences and the platform required for AI-powered applications at scale. Through continued innovation and collaboration with Optus, we are advancing connectivity through AI-driven network innovation, helping shape the future of mobile communications and supporting Australia’s leadership in next-generation digital and AI technologies.”

Conclusions:

The Optus-Nokia result is not a commercial 6G launch, but it is a meaningful milestone. A smartphone-form-factor speed record is eye-catching; the more consequential finding is that upper 6 GHz may be deployable on today’s network footprint with far less infrastructure disruption than many expected. That would significantly improve the business case for upper 6 GHz. If network operators can reuse existing sites and achieve coverage similar to 5G 3.5 GHz, then the transition from trial to deployment could be less capital-intensive than many expected.

For network operators, regulators, and vendors, that is the kind of evidence that can shape both deployment strategy and spectrum decisions. If upper 6 GHz continues to perform this well in additional trials, it could become one of the most important bands in the transition from 5G-Advanced to 6G.

Frequently Asked Questions:

What is massive MIMO and why does the antenna element count matter for upper 6GHz performance?

Massive MIMO (multiple-input multiple-output) is a technology that uses a large array of antennas at a base station to serve multiple users simultaneously in the same frequency resource, using spatial beamforming to direct signal energy precisely toward each device. Higher frequencies like upper 6GHz experience greater signal loss over distance than lower 5G frequencies — so more antenna elements are needed to compensate through more precise beamforming gain. The Nokia antenna in the Optus trial packs 768 elements into a proof-of-concept unit; commercial 5G radios typically use around 192. That difference in element count is the primary reason the Optus trial reached 3.5Gbps while Vodafone’s October 2025 trial with a less advanced antenna reached 2.5Gbps using the same 200MHz bandwidth.

Will upper 6GHz 6G services actually reach consumers without new towers being built?

The Optus trial’s outdoor coverage result suggests it may be possible — but only if the antenna hardware at existing sites is upgraded. The 768-element Nokia antenna compensates for upper 6GHz’s higher path loss through beamforming, matching the coverage footprint of a 3.5GHz 5G cell. Nokia’s CTO has previously confirmed that a 768-element array at 7GHz can fit in approximately the same physical enclosure as a standard 5G unit, because the higher frequency means each element is smaller. If that holds through production hardware, operators could upgrade existing sites rather than build new ones — a critical factor in the cost and timeline of any 6G rollout.

Why does Australia’s spectrum regulator have to decide about upper 6GHz, and what are the options?

The upper 6GHz band (6,425–7,125MHz) is currently under a spectrum embargo from ACMA, meaning no new licenses can be issued while it evaluates how to use the band. The core decision is whether to allocate upper 6GHz to licensed mobile networks (enabling 6G), to unlicensed Wi-Fi (enabling Wi-Fi 6E/7 at higher outdoor power), or to some sharing framework. Mobile operators argue they need the spectrum for future 6G. The Wi-Fi industry argues the same spectrum would dramatically expand outdoor Wi-Fi capacity. There is no technical path that gives both industries full access to the same frequencies simultaneously — ACMA will need to choose, and the Optus-Nokia trial results are now part of the evidence base it will weigh.

What happens globally if countries allocate upper 6GHz differently — mobile in some, Wi-Fi in others?

This is the central risk that the GSMA and mobile standards bodies have identified since WRC-23. If a significant portion of the world’s population — particularly the US, which has already dedicated the full 6GHz band to unlicensed Wi-Fi — does not align on upper 6GHz for mobile, device manufacturers will face a fragmented market: 6G handsets designed for global use cannot rely on upper 6GHz connectivity in all markets. The result would be regional rather than global 6G ecosystems, with separate equipment lines and higher costs. Australia’s decision, while one country among many, will contribute to the critical-mass calculation for whether the WRC-23 mobile identification becomes commercially viable or remains a regulatory aspiration without a unified device ecosystem behind it.

Ookla: U.S. dominates global WiFi 7 while adoption grew 4X to 7.2% by Q1-2026

Posted on August 5, 2026 by Alan Weissberger

Introduction:

According to Ookla’s new WiFi report, cablecos Spectrum (Charter) is the largest Wi-Fi 7 provider in the world! WiFi 7 is actually IEEE 802.11be, also known as Extremely High Throughput (EHT).

Following Ookla’s recent report on The Global State of Wi-Fi , this article focuses on the U.S. and updates last year’s Wi-Fi 7 Speeds Up in the U.S. report. Key points:

Adoption of Wi-Fi 7—the latest Wi-Fi generation currently in market deployment—has only just started to gain meaningful traction in the United States.
Prototypes for Wi-Fi 8 are expected soon, and commercial availability could follow in roughly two years. Meanwhile, discussion of Wi-Fi 9 is already beginning among industry observers.
Fiber drives penetration, Cable drives scale: National Wi-Fi 7 adoption hit 7.2% in Q1 2026. Non-cable ISPs led in customer base penetration by CenturyLink (14.7%) and Frontier (14.3%). Cable giants owned the total volume, with Spectrum alone commanding 24.9% of all U.S. Wi-Fi 7 Speedtest samples.
U.S. dominated global Wi-Fi 7 footprint: U.S. providers accounted for half of the top 10 Wi-Fi 7 networks globally by sample volume, with Spectrum taking the #1 spot in the world, followed by Comcast Xfinity at #2.
Cable upstream upgrades paying off: Cable’s spectrum splits combined with Wi-Fi 7 drove large performance gains, particularly for Xfinity’s median Wi-Fi 7 upload speeds, which more than doubled YoY to 108.8 Mbps.
6 GHz band enters the mainstream: Unlicensed 6 GHz spectrum usage jumped 62% YoY to represent 13.8% of total U.S. Wi-Fi sample traffic, reflecting both router upgrades and user device (smartphone/laptop) maturity.
FCC security rules won’t stifle next-gen Wi-Fi: While foreign router restrictions initially cast a broad net, the FCC’s conditional approval process established a de facto ban isolated to Chinese entities. Because Chinese vendors hold nearly no share of 6 GHz / Wi-Fi 7 hardware, regulatory actions appear unlikely to impede U.S. Wi-Fi 7 rollout momentum.

Wi-Fi 7 is finally here:

Wi-Fi 7 began commercial rollout in early 2024. At the end of Q1 2024, Speedtest samples showed adoption below 1%. One year later, sample shares remained in the low single digits across providers, reaching only 1.8% overall in Q1 2025. By Q1 2026, however, Wi-Fi 7 adoption had increased by 300%, reaching a 7.2% share of Wi-Fi router generations across all providers. That average masks substantial variation by operator. Among leading providers, CenturyLink (14.7%) and Frontier Fiber (14.3%) were about twice the national adoption rate, while Ziply Fiber (13.3%) and MetroNet (13.0%) were also close to that level. These customer bases appear to be moving from the early-adopter phase toward the early majority, using the terminology of Crossing the Chasm.

The cable operators Cox, Spectrum, and Xfinity reported lower Wi-Fi 7 shares among their own customer samples—4.5%, 6.6%, and 4.0%, respectively—than the national average. However, because of their large subscriber bases, their relative importance becomes more apparent when Wi-Fi 7 samples are measured as a share of all U.S. Wi-Fi 7 observations. On that basis, Spectrum’s 6.6% share within its customer base translated to 24.9% of all U.S. Wi-Fi 7 samples in Q1 2026.

CableCos: The cable companies Cox, Spectrum, and Xfinity had relatively lower shares of Wi-Fi 7 samples (4.5%, 6.6%, and 4.0%) than the national average. However, with Spectrum’s and Xfinity’s large customer bases, their Wi-Fi 7 leadership is revealed by flipping from Wi-Fi 7 adoption among providers’ customer base to a providers’ share of all Wi-Fi 7 Speedtest samples. In other words, Spectrum’s 6.6% share of Wi-Fi 7 Speedtest users in its customer base (above), instead compared to all Wi-Fi 7 samples in the U.S. reveals that Spectrum owned a quarter (24.9%) of all Wi-Fi 7 (below) in Q1 2026.

Spectrum’s share of Wi-Fi 7 was 2x larger than Xfinity (12.4%) and Frontier (11.9%). On the other end, the long tail of “Other ISPs” averaged just 0.03% share across the 689 providers measured with Speedtest samples (24.0% all together).

Wi-Fi 7 adoption in the U.S. also leads Wi-Fi 7 globally. Based on its share of Speedtest samples, Spectrum is the world’s largest provider of Wi-Fi 7, heading a pack of five U.S. providers out of the top 10.

Top 10 Rank of Global Wi-Fi 7 Speedtest Samples, Q1 2026

Rank	Provider	Country
1	Spectrum	United States
2	Xfinity	United States
3	China Telecom	China
4	Frontier Fiber	United States
5	WINDTRE	Italy
6	AT&T Fiber	United States
7	Free	France
8	CenturyLink	United States
9	China Unicom	China
10	HiNet	Taiwan

Spectrum will add to its total of Wi-Fi 7 users when parent Charter Communications completes its anticipated Cox Communications merger in mid-to-late August. However, as a share of its own customer base, Cox had just 4.5% of its customers measured on Wi-Fi 7 with Speedtest samples. This will slightly dilute the share of Wi-Fi 7 of the merged entity’s base.

China Telecom and China Unicom make the list because their customer bases are massive (439 million mobile subscribers and 232 million 5G network customers in Q4 2025, respectively). However, the 6 GHz spectrum band in China, that Wi-Fi 7 could take advantage of, is licensed for mobile telecommunications (i.e., 5G and 6G) rather than for public, unlicensed Wi-Fi use.

More spectrum, more capacity, faster Wi-Fi:

Adoption of Wi-Fi 7 (and Wi-Fi 6E) has led to increased use of the 6 GHz spectrum frequency band (1,200 MHz from 5.925 GHz to 7.125 GHz of unlicensed spectrum). The growth in the use of this band not only comes from Wi-Fi routers, but also the end-user device – laptops, tablets, and smartphones. (Both ends of the connection require the newer Wi-Fi technology capability.) 6 GHz usage increased 62% from Q1 2025 to Q1 2026, accounting for 13.8% of Speedtest samples in the U.S.

Ericsson leads SK Telecom AI RAN vs. NVIDIA’s GPU centric AI RAN Alliance

Posted on August 4, 2026 by Alan Weissberger

Executive Summary:

Ericsson says it has been selected as the sole global technology partner in SK Telecom’s consortium for Korea’s Hyper-AI Network Infrastructure Demonstration Project, a South Korea government-backed initiative led by the Ministry of Science and ICT and the National Information Society Agency. The program is intended to validate AI-RAN pilot networks as a cornerstone of Korea’s national “AI Highway” strategy and its longer-term 6G roadmap.

Ericsson’s contribution [1.] to this project centers on the RAN and the automation layer that surrounds it. According to Ericsson, its role in the project includes 5G Standalone expertise, AI-in-RAN capabilities, and intelligent network automation through the Ericsson Intelligent Automation Platform (EIAP) and AI-powered rApps, enabling autonomous control, resource orchestration, and real-time optimization for physical AI services. Ericsson is not being positioned as a general AI infrastructure provider, but as the core network technology partner bringing telco-grade RAN, automation, and orchestration into a live industrial validation environment. Ericsson will contribute what it calls an “end-to-end network foundation” to the project that is intended to connect and continuously optimize intelligent machines and autonomous industrial operations. In the second phase of the project, Ericsson’s AI-RAN pilot network is expected to be applied to a real-world logistics environment at KG Mobility’s Pyeongtaek plant.

Note 1. It’s interesting to note that Ericsson is a founding member of the Nvidia GPU centric AI-RAN Alliance, contributing the operator-centric “AI-for-RAN” perspective by embedding telco-grade AI into basebands and radios to improve network performance, automation, and energy efficiency. The company’s delegates hold leadership roles in the alliance’s working groups and technical committees.

For telecom operators, the significance is not just radio performance but the shift toward a network architecture that can support physical AI use cases with tighter latency, stronger uplink capacity, and higher service assurance. SK Telecom plans to demonstrate AI-RAN pilots through 2027 across scenarios such as autonomous transport, industrial safety monitoring, and humanoid robotics, with a second-phase deployment targeted for KG Mobility’s Pyeongtaek plant.

Sibel Tombaz, Head of Customer Unit Korea, Ericsson, says: “Being selected as a key global technology partner in this government-backed Hyper-AI Network consortium is a significant recognition of Ericsson’s technology leadership and our long-term partnership with SK Telecom. Korea is moving with clear ambition to shape the future of AI-native networks and 6G, and Ericsson is proud to contribute our global expertise in 5G, AI-RAN, orchestration, and intelligent network automation to this important national initiative. We look forward to working closely with SK Telecom and the consortium partners to help turn Korea’s 6G vision into real industrial value.”

Takki Yu, VP and Head of Network R&D at SK Telecom, says: “As a key national project supporting Korea’s Hyper-AI Network strategy, SK Telecom is pleased to collaborate with Ericsson as a key technology partner to advance AI-RAN technology through global cooperation. Together, we aim to build a strategic win-win partnership, demonstrate real industrial value, and help strengthen Korea’s AI-RAN technology capabilities and ecosystem for the future.”

Comparison with NVIDIA GPU centric AI-RAN Alliance:

The SK Telecom–Ericsson initiative and the NVIDIA-led AI-RAN ecosystem share a common thesis: the RAN is evolving into a distributed compute platform that can host or coordinate AI workloads closer to where data is generated. But they emphasize different layers of the stack. SK Telecom’s Ericsson-led project is centered on operator-grade RAN validation, network autonomy, and physical AI service delivery in industrial settings, while NVIDIA’s effort is broader and more compute-centric, tied to AI factories, GPU infrastructure, and open 6G ecosystem development.

NVIDIA is a founding member of the AI-RAN Alliance and acts as one of its most visible technical drivers, contributing reference architectures and accelerated-computing platforms for AI-RAN.
Ericsson is the operator-focused RAN technology partner proving AI-RAN in live telco and industrial network deployments.

Dimension	SK Telecom + Ericsson	NVIDIA-led AI-RAN Alliance
Primary focus	AI-RAN pilot networks for physical AI and industrial deployment	AI-native infrastructure, open 6G ecosystems, and large-scale AI compute
Core value proposition	RAN performance, autonomy, orchestration, and telco-grade service assurance	Accelerated computing, AI factories, and programmable AI-native network platforms
Typical emphasis	5G Standalone, differentiated connectivity, uplink, mobility, and low-latency industrial use cases	Full-stack AI infrastructure and ecosystem alignment for next-generation wireless
Deployment style	Operator-led pilots and real-world industrial validation	Multi-stakeholder architecture and platform collaboration across telecom and compute
Korea relevance	National “AI Highway” and physical AI demonstrations	AI cloud and broader AI infrastructure development in Korea

The practical takeaway is that Ericsson’s role is more narrowly telecom-native, while NVIDIA’s consortium is more infrastructure- and compute-oriented. For 6G, the two approaches are complementary rather than contradictory: one is proving how the network behaves as a deterministic industrial platform, the other is building the compute substrate that can feed AI-native services into that platform.ericsson+2

Why it matters:

SKT announced the Hyper-AI Network Infrastructure Development project last month, and at the time Ericsson, Nokia, Samsung and private mobile networking specialist HFR were named as those providing the kit and related network and software solutions.

South Korea has become one of the most advanced and competitive mobile markets, and this makes it a useful proving ground for AI-RAN. If the SK Telecom pilot succeeds, it could strengthen the case that future mobile networks must support not only connectivity, but distributed inference, orchestration, and machine control for robots, vehicles, and industrial systems.

From a standards and market perspective, the more interesting question is how these pilots influence the eventual division of labor between RAN, edge compute, and centralized AI infrastructure in 6G-era networks. That is where the SK Telecom–Ericsson model, with its operator-led network validation, may prove especially influential.

How NTIA “Call to Action for 6G Leadership and Security” might influence 6G/IMT-2030 standards and 3GPP specifications

Posted on August 3, 2026 by Alan Weissberger

Introduction:

The U.S. National Telecommunications and Information Administration (NTIA) has launched the “Call to Action for 6G Leadership and Security,” a multilateral initiative uniting more than 20 like-minded governments to coordinate on a shared vision for open, interoperable, secure, and resilient 6G networks. While politically significant, the effort operates alongside—not in place of—the established technical standards ecosystem led by 3GPP and ITU-R, and its impact will hinge on closing critical supply-chain and participation gaps.

“The Call to Action for 6G Leadership and Security reflects an unprecedented level of international coordination on the future of communications technology,” said Arielle Roth, Assistant Secretary of Commerce for Communications and Information and NTIA Administrator. “Today’s action recognizes that 6G will be dramatically different from 5G, and that advancing U.S. and allied leadership requires a dramatically different playbook. By working now with trusted partners, we will ensure that next generation networks reflect our shared security interests, strengthen our competitiveness, and drive innovation. I am proud of the role NTIA has played in building this global partnership, and I look forward to seeing our shared commitments translated into meaningful action.”

NTIA is launching this initiative alongside more than 20 partner governments spanning Europe, the Indo-Pacific, and the Western Hemisphere. Through the Call to Action, participating governments have pledged to strengthen cooperation on 6G over the next 12 months and beyond in support of security, interoperability, and resilience in next generation networks. The initiative also recognizes that trusted artificial intelligence (AI) will be central to the development and operation of secure and innovative 6G networks for the United States and its global partners.

Initiative scope and strategic alignment:

The Call to Action explicitly advances the objectives of President Trump’s December 2025 Presidential Memorandum on “Winning the 6G Race,” which frames 6G as foundational to U.S. national security, foreign policy, and economic prosperity. Participating governments commit to strengthening cooperation over the next 12 months and beyond on security, interoperability, and resilience, with an emphasis on trusted AI as central to 6G operations. The document also stresses avoiding duplication with industry-driven standards bodies while exploring constructive interfaces with private-sector stakeholders.

Initial milestones include establishing government points of contact, engaging industry and academia, identifying barriers to leadership, and exploring ways to strengthen secure and resilient supply chains.

Membership composition and notable absences:

The coalition includes the United States and key advanced-economy partners with strong mobile capabilities and intellectual property portfolios—among them Finland, Sweden, Japan, and South Korea—alongside a broader set of allies across Europe, the Indo-Pacific, and the Western Hemisphere. However, several strategically important economies are not signatories, including India, Vietnam, and Taiwan, as well as Thailand, Malaysia, and Mexico.ntia+2

India and Taiwan participate in various Huawei-free supply initiatives but are not part of this specific Call to Action.
Vietnam maintains a cautious posture toward China and has pursued domestic 5G equipment development, yet it remains outside the current framework.

These absences matter because 6G security is only as strong as its end-to-end supply chain. A credible security posture requires participation from low- to medium-cost manufacturing hubs aspiring to grow their hardware sectors—an endeavor that demands coordinated reshoring and friend-shoring at scale.

Standards reality check – 3GPP and ITU-R WP5D remain responsible:

This NTIA led alliance is a high-level political and policy forum; it does not set 6G standards or specifications. The NTIA will likely shape U.S. positions and coordinate federal input so that U.S. industry contributions to 3GPP and ITU‑R reflect national security, spectrum, and innovation priorities. In practice, NTIA’s role is policy, spectrum, and interagency coordination, while the detailed 6G standards are produced by 3GPP and then submitted to ITU‑R WP5D for IMT‑2030 approval. Technical standardization will continue to be driven by:

3GPP Release 21, expected to deliver the first set of 3GPP 6G technical specifications and serve as the basis for IMT-2030 submission before 2030.
- The Release 21 timeline is to be finalized by June 2026, with ASN.1/OpenAPI freeze no earlier than March 2029 (some industry views target end-2028).
ITU-R WP5D, which is developing the IMT-2030 framework and evaluation guidelines, and has opened a submission window for candidate Radio Interface Technologies (RIT/SRIT) from February 2027 to February 2029.itu+3

IMT-2030 RIT/SRIT submissions are expected to align closely with 3GPP Release 21 outputs. The Call to Action can help smooth policy disagreements and align security priorities, but it cannot override or replace these processes; at worst, it risks adding another layer of complexity or politicization if not carefully scoped.

How NTIA interfaces with 3GPP:

Policy and requirements feed‑in: NTIA gathers input from industry, academia, and other agencies (e.g., via its 6G Request for Comments and the Commerce Spectrum Management Advisory Committee) to inform the U.S. government’s 6G policy and priorities. Those priorities—open, interoperable, secure, and reliable architectures; public‑safety needs; and spectrum alignment—are then reflected in U.S. positions carried into 3GPP by U.S. standards bodies and companies.
Standards‑body channel via ATIS: In 3GPP, the U.S. Organizational Partner is ATIS. NTIA does not sit inside 3GPP as a member, but it works with ATIS and U.S. stakeholders to ensure that federal requirements (e.g., for public safety, security, and spectrum harmonization) are represented in 3GPP work items and technical reports. For example, the FirstNet Authority (working under a congressional mandate) actively participates in 3GPP to advance public‑safety requirements into 5G‑Advanced and 6G.
Spectrum and R&D alignment: NTIA’s National Spectrum Strategy and federal R&D programs are designed to make sure that the bands and research directions needed for 6G are available and de‑risked before 3GPP locks in key radio and system designs. This indirectly shapes what is feasible in 3GPP Release 21 (the expected first 6G release).

How NTIA interfaces with ITU‑R WP5D (IMT‑2030):

U.S. administration role in ITU‑R: NTIA is the U.S. administration for ITU‑R matters. It coordinates U.S. government positions, prepares proposals, and supports U.S. delegations at ITU‑R WP5D meetings, including WP5D’s work on IMT‑2030 (6G) RIT/SRITs.
Requirements and evaluation framework: ITU‑R WP5D defines the IMT‑2030 framework, minimum performance requirements, and evaluation guidelines for candidate 6G radio technologies (RIT/SRIT). NTIA helps ensure that U.S. views on security, resilience, spectrum, and public‑safety are reflected in these high‑level requirements and evaluation criteria.
From 3GPP specs to IMT approval: 3GPP develops the actual 6G technical specifications (expected to be completed around 2028–2029 for Release 21) and, through ATIS, submits them to ITU‑R WP5D as the primary IMT‑2030 candidate. WP5D then evaluates the candidates against its requirements and, if they pass, incorporates them into ITU Recommendations. NTIA’s role here is to coordinate the U.S. position on those evaluations and the resulting Recommendations, not to write the 3GPP specs themselves.

In summary NTIA influences 6G standards indirectly—through spectrum policy, federal R&D, interagency coordination, and U.S. positions in ITU‑R—while relying on ATIS and U.S. industry to carry those priorities into 3GPP’s technical work and into ITU‑R’s IMT‑2030 process.

Implications for 6G security and supply-chain resilience:

The new NTIA‑led Call to Action is a multilateral policy forum which could:

Align partner governments on shared security and interoperability principles that then inform national positions in 3GPP and ITU‑R.
Support supply‑chain and trusted‑AI initiatives that underpin secure 6G deployments, complementing the technical standards produced by 3GPP and approved by ITU‑R.

The initiative’s greatest value lies in creating a trusted, action-oriented forum to:

Coordinate on security-by-design principles, including open interfaces, interoperability, and resilience requirements that can feed into national procurement and regulatory frameworks.benton+1
Accelerate trusted AI integration into 6G network operations and management.ntia+1
Map and mitigate supply-chain vulnerabilities, especially for radio access network (RAN) components, semiconductors, and test/measurement ecosystems.

However, without bringing in pivotal manufacturing and assembly locations—particularly in South and Southeast Asia and Latin America—the alliance risks leaving the most exposed links in the 6G supply chain unaddressed.

From political alignment to measurable impact:

Given the proliferation of 6G alliances, the Call to Action must demonstrate tangible progress to remain relevant. Priority actions include:

Operationalize working groups within 12 months to produce concrete guidance on secure RAN architectures, AI-enabled operations, and resilience metrics.ntia+1
Bridge to standards work by channeling consensus positions into 3GPP and ITU-R via national standards bodies and industry coalitions, without duplicating technical workstreams.benton+1
Expand the circle by engaging non-signatory economies through targeted supply-chain and innovation programs, making participation economically attractive to members.

If executed with discipline, the Call to Action can reduce fragmentation, elevate security baselines, and de-risk the path to commercial 6G. If not, it may become another layer of diplomacy with limited effect on the technical and industrial realities that will define 6G.
