Analysis and Impact of Blockbuster FCC ban on foreign made WiFi routers
On March 23rd, the Federal Communications Commission (FCC) updated its Covered List to prohibit the sale of foreign made consumer-grade (WiFi) routers to be sold in the U.S. The FCC’s Covered List is a list of communications equipment and services that are deemed to pose an unacceptable risk to the national security of the U.S. or the safety and security of U.S. persons. This FCC decision follows a determination by an Executive Branch interagency body, which concluded those devices pose unacceptable risks to U.S. national security and the safety of its citizens. . The new FCC restriction applies strictly to new foreign made router models, meaning retailers can continue marketing previously approved units and consumers can operate their existing equipment without interruption.
Impact:
TP-Link, Netgear, and Asus are currently among the top-selling Wi-Fi router brands in the U.S. consumer market. Estimates for early 2026 indicate that TP-Link alone holds approximately 35% of the U.S. consumer router market share, while Netgear and Asus collectively account for another 25%. The TP-Link Archer AXE75 is frequently rated the best router for most users due to its Wi-Fi 6E speed and reasonable price.

Linksys and Ubiquiti are American-based companies, but their hardware is produced by contract manufacturers overseas in locations like China, Vietnam, and Taiwan. Similarly, Amazon eero and Google Nest mesh routers are not made in the U.S.
–>Hence, these companies ability to sell new WiFi router models in the U.S. is now facing strict regulatory hurdles.
Quotes:
FCC Chairman Brendan Carr said: “I welcome this Executive Branch national security determination, and I am pleased that the FCC has now added foreign-produced routers, which were found to pose an unacceptable national security risk, to the FCC’s Covered List. “Following President Trump’s leadership, the FCC will continue to do our part in making sure that US cyberspace, critical infrastructure, and supply chains are safe and secure.”
Bogdan Botezatu, director of Threat Research at cybersecurity firm Bitdefender, says this ban is a step to harden the cybersecurity readiness of U.S. households, given ongoing geopolitical tensions. “Consumer routers sit at the edge of every home network, which makes them an attractive target and a strategic risk if compromised at scale,” he says. Asked whether he thinks the risk is real, Botezatu says the risk is real, though there’s no easy way to prove intent. “[Internet of Things] devices, including routers, are a weak point across the internet.”
“Virtually all (WiFi) routers are made outside the United States, including those produced by US-based companies like TP-Link, which manufactures its products in Vietnam,” a spokesperson from TP-Link tells WIRED. “It appears that the entire router industry will be impacted by the FCC’s announcement concerning new devices not previously authorized by the FCC.”
- Reduced Product Availability: New, high-performance routers manufactured outside the U.S. will not receive the necessary approval to be imported or sold, restricting future consumer choices.
- Higher Costs: The, “This ruling has the potential to significantly disrupt the U.S. consumer router market,” according to, likely resulting in increased prices for consumers as companies grapple with new regulatory requirements.
- Shift in Manufacturing: Router manufacturers, including those targeting the U.S. market, will likely need to shift production to the U.S. to satisfy security concerns and bypass the ban, says PC Magazine.
- Security Focus: The ban targets vulnerabilities in foreign hardware and firmware.
- No Impact on Existing Devices: Consumers can continue to use routers they currently own

Semtech LoRa® PHY technology enables Amazon Sidewalk to expand while supporting fixed and mobile IoT endpoints
Introduction:
Semtech Corporation, a leading provider of high-performance semiconductor, Internet of Things (IoT) systems and cloud connectivity service solutions, is the creator and primary owner of the intellectual property (IP) for LoRa® technology, providing the Physical layer chips (PHY transceivers) used in LoRaWAN – the very popular Low Power Wide Area Network (LPWAN) for IoT endpoints.
The Camarillo, CA based company last week announced that LoRa® technology will continue to serve as the core radio modulation for Amazon Sidewalk across all markets in this year’s Sidewalk international expansion. Sidewalk’s global expansion officially begins in Canada and Mexico with further expansion to other international regions is scheduled for later in 2026. The network is projected to expand to over 30 new countries by year’s end.
Amazon Sidewalk is increasingly viewed as a commercial success in terms of infrastructure deployment and technical capability, transitioning from a niche smart home feature to a broad, LoRa-based Low Power Wide Area Network (LPWAN). While it faced initial skepticism regarding privacy and adoption, the network now boasts massive, passive coverage of over 95% of the U.S. population and is undergoing rapid international expansion.
Architectural role of LoRa in Sidewalk:
LoRa is the de facto wireless platform of LPWANs for IoT. Semtech’s LoRa chipsets connect sensors to the Cloud and enable real-time communication of data and analytics that can be utilized to enhance efficiency and productivity. LoRa devices enable smart IoT applications that solve some of the biggest challenges facing our planet: energy management, natural resource reduction, pollution control, and infrastructure efficiency.
Amazon Sidewalk aggregates spectrum in unlicensed bands and combines multiple physical layers, with Semtech’s LoRa modulation providing the long‑range, low‑power tier for neighborhood‑scale coverage beyond home Wi‑Fi and short‑range Personal Area Networks (PANs). By using ONLY LoRa as the core wide‑area PHY, Sidewalk evolves from a home‑centric LAN into a geographically distributed WAN that can support both fixed and mobile IoT endpoints across dense residential environments.
Network scale and coverage:
Sidewalk already covers roughly 95% of the U.S. population, making it one of the largest license‑free, consumer‑facing LPWA deployments, and the 2026 roadmap extends the footprint into Canada and Mexico first, followed by additional international markets later in the year. This expansion effectively turns Sidewalk into a multi‑continent overlay network, leveraging existing consumer premises equipment and LoRa‑enabled endpoints to provide persistent connectivity without requiring dedicated operator‑grade RAN build‑outs.
Technology differentiation vs other LPWAN options:
NB-IoT (included in ITU-R M.2150 IMT 2020 RIT/SRIT standard) holds the largest LPWAN share at roughly 54%–58% of total LPWAN connections, due to massive adoption in China which accounts for approximately 84% of all global NB-IoT connections. Outside of China, LoRaWAN is the clear market leader with a 41% share of connections. As of late 2025, there are over 125 million LoRaWAN end devices deployed globally, growing at a 25% annual rate. It is the preferred choice for private IoT networks, specifically in smart buildings, agriculture, and industrial asset tracking.
LoRa’s combination of long range, ultra‑low power operation, and mature ecosystem (silicon, gateways, and cloud stacks) gives Sidewalk a differentiated profile relative to alternatives such as narrowband cellular IoT and other unlicensed LPWAN modulation methods. For Amazon, anchoring Sidewalk on LoRa reduces RF and protocol fragmentation on the end‑device side while preserving flexibility to layer higher‑level Sidewalk services and security on top of the underlying LoRa/LoRaWAN protocol stack.
Market and ecosystem context:
Amazon Sidewalk now sits alongside large industrial and enterprise LoRaWAN networks, reinforcing LoRa’s position as the leading low‑power wide‑area connectivity technology in unlicensed spectrum. The LoRaWAN IoT connectivity market is forecast to grow from about 10.7 billion USD in 2025 to 44.8 billion USD by 2030 (33.1% CAGR), while LoRaWAN deployments have surpassed 125 million devices globally with a 25% CAGR, signaling a robust runway for Sidewalk‑class Massive IoT use cases.
Implications for device and service design:
For device OEMs and service providers, Amazon’s decision effectively de‑risks LoRa as a long‑term connectivity bet for consumer and prosumer IoT, given Sidewalk’s trajectory to tens of millions of active devices worldwide. Vendors integrating LoRa‑based designs can now target both traditional LoRaWAN operator networks and the Sidewalk ecosystem, enabling common hardware platforms to support smart home, safety, environmental monitoring, and asset‑tracking applications at neighborhood and city scale.
LoRa Enables Sidewalk’s Technical Evolution:
Chirp spread spectrum (CSS) modulation in LoRa technology provides the technical foundation enabling Amazon Sidewalk’s new capabilities:
- Enhanced Network Density: LoRa multi-spreading factor capability optimizes longer range and shorter time-on-air, supporting higher device concentrations in urban environments while maintaining reliable connectivity.
- Location-Based Services: Unique location accuracy service that combines the power of Wi-Fi, Bluetooth Low Energy (BLE) and GPS enables a new class of location aware devices that don’t need expensive cellular solutions for asset tracking applications.
- Hub-Less Deployments: Utilized for both out-of-band-diagnostics as well as signaling radio for battery-powered cameras, LoRa lowers the need for hubs/repeaters, reducing infrastructure complexity for consumers while extending effective coverage areas.
Proven Heritage of LoRa in Massive IoT Networks:
Semtech’s LoRa technology has been deployed by more than 170 major mobile network operators globally, with over 500 million connected devices across smart cities, utilities, logistics, unmanned aircraft systems, and industrial applications. This proven deployment heritage provides the technical foundation and ecosystem maturity required for Amazon Sidewalk’s global expansion.
The technology’s long-range capability, extending connectivity up to several kilometers from Sidewalk bridge devices, combined with its ability to penetrate buildings and operate in dense urban environments makes it uniquely suited for neighborhood-scale networks. LoRa provides free, long-range connectivity that consumers can rely on for years of battery-powered operation.
Building on CES 2026 Momentum:
Ring showcased its expanded product portfolio using LoRa at CES 2026, introducing comprehensive sensor families for security, safety and home automation. These products join the growing network of devices powered on Sidewalk, including water leak and freeze detection sensors, wearable devices and environmental monitoring solutions, all leveraging the connectivity advantages of LoRa.
The Sidewalk network’s architecture—combining LoRa for long-range communication with Bluetooth Low Energy for device setup—creates a robust, resilient IoT infrastructure that can scale to support millions of devices while maintaining the ultra-low power consumption critical for battery-operated sensors and cameras.

Taara Lightbridge Pro: an ultra reliable wireless optical communications system for 5G mobile backhaul
Google moonshot factory X graduate Taara [1.] is launching Lightbridge Pro, a wireless optical communications system designed to deliver 99.999% (“five nines”) carrier-grade uptime for 20 Gbps backhaul, addressing weather-related reliability issues in Free Space Optical Communication (FSOC).
Lightbridge Pro is designed for seamless integration into carrier-grade networks, including mobile backhaul and mission-critical infrastructure. By integrating intelligent optical switching directly into the hardware, it automatically reroutes traffic to fiber or RF backups during, for example, heavy fog or rain.
Note 1. Tara says that for the last eight years, they have been developing novel technology that uses beams of light to deliver high-speed, secure connectivity where fiber and wireless can’t – bringing abundant access to everyone, everywhere.
“As demand for data soars, existing connectivity solutions are reaching their limits. What if we could harness the power of light to deliver a better, faster, more efficient connection, without the need for cables?” Mahesh Krishnaswamy, Founder and CEO.
Key Features and Impact:
Carrier-Grade Reliability: Lightbridge Pro is purpose-built for high-availability requirements of 5G mobile backhaul,, and city-wide network providers.
Intelligent Switching: The system ensures seamless, near-instantaneous, switching between optical and backup connections (like RF) to maintain continuity.
Performance: It delivers up to 20 Gbps full-duplex capacity, bridging gaps where fiber installation is too costly or difficult.
Global Application: Already deployed in over 20 countries, the technology is used in dense urban, rural, and disaster recovery scenarios.
Operational Efficiency: The system includes comprehensive Fault, Configuration, Accounting, Performance, and Security (FCAPS) management, suitable for integration with existing Operations and Business Support Systems (OSS/BSS).
Deployment and Use Cases: Tara’s platform is aimed at large-scale network operators and mission-critical communications, particularly in dense urban environments or rough terrain where laying fiber is not economically viable.
Current Partners: Taara Lightbridge is already deployed in more than 20 countries, from dense urban cores to remote terrain to disaster recovery scenarios. Carriers already using Taara’s technology include Airtel, T-Mobile, SoftBank, Digicel, and Liquid Intelligent Technologies. T-Mobile previously deployed Taara units for high-capacity backhaul at Coachella and the Albuquerque Balloon Festival.
………………………………………………………………………………………………………………………………………………………………………..
Taara is showcasing these new solutions at Mobile World Congress (MWC) Barcelona 2026 where the start-up will also be announcing a new photonics-based wireless optical system designed for even greater density and scalability.
………………………………………………………………………………………………………………………………………………………………………..
Editor’s Analysis:
Taara’s Lightbridge Pro looks like a serious, carrier-minded evolution of free-space optics (FSO) for 5G backhaul, but its real value will hinge on how well the “five nines” claim holds up under diverse atmospheric and operational conditions in the field.
Risks and open questions:
-
SLA realism: “Five nines” across mixed optical/RF paths is a strong claim; operators will want multi-year availability data by climate region, plus clear modeling of residual outage during extreme events where both optical and RF paths can degrade.
-
Operational complexity: Even with integrated switching and FCAPS, adding a new transport technology introduces planning, monitoring, and skillset overhead versus staying on homogeneous fiber/microwave.
-
Regulatory and spectrum: Where RF is the backup, spectrum licensing, interference management, and coordination with existing microwave/E‑band layers will affect total cost and deployment speed, and those aspects are not detailed in the product material.
Overall assessment:
For 5G mobile backhaul, Lightbridge Pro is best viewed as a targeted tool for high-value, hard-to-fiber routes, and for rapid-capacity or temporary deployments, rather than a universal replacement for fiber or microwave. If Taara’s integrated protection switching performs as advertised at scale, it meaningfully advances FSO from “interesting niche” to a credible part of a multi-layer transport strategy for carriers and city-scale operators.

India 5G subscribers top 400 Million with rapid adoption continuing without 5Gi
With over 400 million 5G subscribers, India now ranks #2 globally (China is #1 [1.]). What’s even more remarkable is the speed of adoption after 5G spectrum auctions were repeatedly delayed. Jyotiraditya Scindia, India’s union minister for communications and development of the North Eastern Region, said the country is “setting new global benchmarks in scale, speed and digital transformation.”
According to figures cited by the minister, the country’s 5G subscriber base now exceeds that of other major markets, including the United States with around 350 million users, the European Union with 200 million, and Japan with 190 million. China remains the global leader, with more than 1.2 billion 5G connections.
Note 1. China has over 1.2 billion 5G subscribers as of late 2025, representing over 60% of all mobile connections in the country, driven by massive infrastructure rollout and strong adoption across major operators like China Mobile, China Telecom, and China Unicom, making it the global leader in 5G penetration.
……………………………………………………………………………………………………………………………………………………………………………………………………..
Bharti Airtel and Reliance Jio Infocomm spearheaded the launch, becoming the first carriers to operationalize 5G networks and achieving significant subscriber acquisition, with each surpassing the 50 million user milestone within their initial year of service [1]. Vodafone Idea subsequently entered the 5G market with launches in specific cities during 2025.
State-owned telecom provider BSNL is projected to launch 5G services within the current year [1]. This deployment is slated to exclusively utilize India’s indigenously developed telecom technology stack, a collaborative effort involving the Centre for Development of Telematics (C-DOT), Tejas Networks, and Tata Consultancy Services (TCS).
As of the close of 2025, the national 5G infrastructure comprised 518,854 operational base stations, marking a substantial increase from approximately 464,990 recorded at the start of the year [1]. The Department of Telecommunications (DoT) reported the deployment of 4,112 new 5G base transceiver stations (BTS) in December 2025 alone, contributing to the year-end cumulative total
- Infrastructure Growth: Rapid BTS deployment, exceeding 4,100 new installations in December 2025 alone, demonstrates intense network densification, with coverage now reaching most districts.
- Vodafone Idea’s Entry: Vi, after initial delays, commenced its phased 5G service introduction in select cities during 2025.
- BSNL’s Indigenous Strategy: The state-owned operator is slated to launch 5G using India’s homegrown stack (C-DOT, Tejas, TCS), showcasing self-reliance in telecom technology.
- Market Dynamics: The rapid expansion aims to unlock enterprise and consumer use cases, positioning India as a significant global 5G player, despite ongoing discussions about monetization and infrastructure investment.
Technical & Deployment Highlights:
- Architecture: A mix of 5G SA (Jio) and 5G NSA (Airtel) is prevalent, with SA offering lower latency and true 5G capabilities.
- Spectrum: Operators utilize various bands, including sub-6 GHz (3.3 GHz, 26 GHz) for broad coverage and capacity.
- Deployment Pace: Driven by ministerial targets, operators installed BTS at an accelerated pace, focusing initially on high-revenue urban centers.
This author deeply regrets that the Telecommunications Standards Development Society India (TSDSI)’s 5Gi RIT specification, included as part of the ITU-R M.2150 IMT 2020 RIT/SRIT standard, was not implemented in India. On January 25, 2022, TSDSI told the Telecommunication Engineering Center (TEC) under the DoT not to proceed with the adoption of 5Gi as a national 5G standard. TSDSI added that it “does not intend to further update 5Gi specifications.”

Sebastian Barros: Using telecom networks for weather sensing requires a strategic telco shift from connectivity providers to ecosystem orchestrators
Telecom networks for weather sensing can be facilitated by using existing microwave links and 4G/5G signals as virtual sensors, detecting changes in signal strength and timing caused by rain, humidity, and temperature, effectively turning vast infrastructure into a dense, real-time atmospheric monitoring system for improved forecasting and disaster alerts, notes Sebastian Barros on Substack. By analyzing signal attenuation, telecom networks create high-resolution weather maps, complementing traditional methods like radar. Yet very few network operators or vendors have attempted to use telecommunications infrastructure for dense atmospheric sensing. The data exists but is rarely activated, processed, or disclosed.
Global Navigation Satellite System (GNSS) [1.] based atmospheric estimation, rain attenuation on microwave links, and radio refractivity effects have been studied for more than 20 years. The physics is well understood and already embedded in network planning and synchronization systems. There are eight million radio sites span cities, roads, ports, factories, and borders. Every site has power, compute, backhaul, antennas, timing, and regulatory protection. Today, the network only provides connectivity. Integrated Sensing and Communication (ISAC) starts to change that. It repurposes radio waves for radar-like sensing, including presence detection, velocity, Doppler shift, and range.
……………………………………………………………………………………………………………………………………………………………………………
Note 1. Global Navigation Satellite System (GNSS) is the umbrella term for satellite constellations like the U.S.’s GPS, Russia’s GLONASS, the EU’s Galileo, and China’s BeiDou, which provide global positioning, navigation, and timing (PNT) services. GNSS receivers use signals from these orbiting satellites to calculate precise locations on Earth, offering increased accuracy and reliability compared to relying on a single system, enabling applications from smartphone navigation to autonomous vehicles and precision agriculture.
……………………………………………………………………………………………………………………………………………………………………………
- Receiver: Your end point receiving device (phone, car navigation, etc.) picks up signals from several of these satellites.
- Calculation: By measuring the time it takes for signals to arrive from at least four satellites, the receiver performs complex calculations (trilateration) to pinpoint your exact position.
Telecom networks can expose not just connectivity but structured awareness: object motion, crowd flow, anomalies, risks, and environmental state. In real time, across every continent. The infrastructure already exists. What’s missing is the architecture and the will to build the sensing layer on top of it. With dense, real-time sensing already in place, telecom can expose environmental intelligence through Open Gateway APIs, just as it exposes location or quality today. No new hardware. No new towers. Just activation, inference at the edge, and exposure.
- Data Siloing: The data produced by ISAC currently remains locked within the physical (PHY) and Media Access Control (MAC) layers of the network. It is primarily used for internal network optimization and is not exposed to external applications or platforms.
- Lack of Abstraction and APIs: There are no standard abstraction layers or Application Programming Interfaces (APIs) that would allow external systems (e.g., weather services, autonomous navigation systems, urban infrastructure management) to access and interpret the raw sensing data.
- Absence of Data Fusion Standards: There is no standard methodology to fuse the output from ISAC with data from other sensing modalities (e.g., vision, audio, thermal sensors). This prevents the creation of a comprehensive, multimodal sensing mesh.
- Missing Marketplace: The lack of standardized access and integration means there is no marketplace for this valuable data, which stifles innovation and collaboration across different industries that could benefit from real-world awareness information.

2025 Year End Review: Integration of Telecom and ICT; What to Expect in 2026
Smart electromagnetic surfaces/RIS: an optimal low-cost design for integrated communications, sensing and powering
Deutsche Telekom: successful completion of the 6G-TakeOff project with “3D networks”
Smart electromagnetic surfaces/RIS: an optimal low-cost design for integrated communications, sensing and powering
Researchers at Xidian University in China have pioneered a smart electromagnetic surface that converts ambient electromagnetic waves into electrical power, marking a potential leap in stealth and wireless technologies. This meta-surface innovation merges advanced electromagnetic engineering with communication principles, enabling self-powered systems for demanding applications. The self-sustaining electronic system integrates wireless information transfer and energy harvesting and has the potential to upend the dynamics of electronic warfare.
The surface facilitates simultaneous energy harvesting and data transmission, drawing power from radar or environmental signals without traditional batteries. Xidian’s team highlights its role in “electromagnetic cooperative stealth,” where networked platforms collaboratively minimize radar cross-sections and sensor detectability. Prototypes demonstrate viability for real-time wave manipulation, building on metasurface designs that dynamically adjust phase and amplitude.
The researchers said this included investigating “electromagnetic cooperative stealth,” where multiple entities work together to reduce their visibility to radar and electromagnetic sensors. In electronic warfare, the technology flips the script on radar threats: stealth aircraft could harvest enemy beams for propulsion or comms, reducing logistical vulnerabilities. This cooperative approach extends to multi-asset formations, enhancing collective invisibility across spectra.
Early tests align with broader Reconfigurable Intelligent Surfaces (RIS), a two-dimensional reflecting surface. RIS advancements facilitate beam steering up to ±45° with low side lobes. According to a paper published in the IEEE Internet of Things magazine last year, RIS could also be used in anti-jamming technology, unmanned aerial vehicle communication and radio surveillance – all of which are difficult to do using older optimization tools.
Reconfigurable intelligent surfaces can also be configured to create intentional radio “dead zones” to mitigate interference and reduce the risk of eavesdropping, according to German electronics manufacturer Rohde & Schwarz. The European Space Agency has further highlighted RIS as a candidate technology for satellite-to-ground communications, where controllable reflection and redirection of signals could help route links around physical obstacles.
For telecommunications, the surface promises 6G breakthroughs like integrated sensing and powering satellites or base stations. China’s lead here could accelerate reconfigurable networks, improving coverage in non-line-of-sight scenarios. Ongoing refinements target complex interactions for higher precision. By including sensing, communication and power into one hardware platform, the device could allow for a range of advanced applications while reducing eavesdropping and interference.
“Ultimately, it is expected to have a broad impact on 6G communications, the Internet of Things, intelligent stealth and other related fields,” the team said in a paper published in the peer-reviewed journal National Science Review last month. Many scientists say that a key area for next-generation wireless communications will be the transmission channel.
Researchers from Fudan University, the University of Sydney and the Commonwealth Scientific and Industrial Research Organization note that, when combined with artificial intelligence (AI), this technology could significantly enhance the security of air-to-ground Internet of Things (IoT) links.
In their latest publication, the Xidian University team describes RIS as a “powerful solution” for future wireless networks, citing its low cost, high programmability and ease of deployment. However, for 6G systems, RIS must support both communication and sensing on a unified hardware platform by integrating data transmission and radar-like functionality to lower cost and optimize spectrum and hardware resource utilization.
Addressing this requirement will demand architectures that can jointly manipulate both scattered electromagnetic waves and actively radiated signals. The researchers propose that an electromagnetic all-in-one radiation–scattering RIS architecture could provide a viable path to meeting this dual-control challenge. “This achieves significant savings in physical space and cost while ensuring multifunctionality across diverse application scenarios,” the team said. The RIS system could also work in a receiver mode to harvest wireless energy to be used to power the meta-surface itself or charge other electronic devices, the paper added.
It could be used for line-of-sight wireless communication, where there is a direct, unobstructed path between a transmitter and receiver, as well as non-line-of-sight wireless communication, in which there is no direct visual link due to physical barriers like buildings.
The proposed RIS “stands out as the optimal low-cost design” for integrated communication and sensing. “In the future, this architecture could enable the development of environment-adaptive integrated sensing and communication systems, micro base stations and relay integrated systems, as well as self-powered sensing systems,” the team said.

Groq and Nvidia in non-exclusive AI Inference technology licensing agreement; top Groq execs joining Nvidia
AI chip startup Groq [1.] today announced that it has entered into a non-exclusive licensing agreement with Nvidia for Groq’s AI inference technology [2.]. The agreement reflects a shared focus on expanding access to high-performance, low cost inference. As part of this agreement, Jonathan Ross, Groq’s Founder, Sunny Madra, Groq’s President, and other members of the Groq team will join Nvidia to help advance and scale the licensed technology. Groq will continue to operate as an independent company with Simon Edwards stepping into the role of Chief Executive Officer. GroqCloud will continue to operate without interruption. It remains to be seen how Groq’s new collaboration with Nvidia will effect its recent partnership with IBM.
Note 1. Founded in 2016, Groq specializes in what is known as inference, where artificial intelligence (AI) models that have already been trained respond to requests from users. While Nvidia dominates the market for training AI models (see Note 2.), it faces much more competition in inference, where traditional rivals such as Advanced Micro Devices have aimed to challenge it as well as startups such as Groq and Cerebras Systems.
Note 2. Training AI models (used by Nvidia GPUs) involves teaching a model to learn patterns from large amounts of data, while AI “inferencing” refers to using that trained model to generate outputs. Both processes demand massive computing power from AI chips.
…………………………………………………………………………………………………………………………………………………………………………………………………….
Groq has achieved a significant financial milestone, elevating its post-money valuation to $6.9 billion from $2.8 billion following a successful $750 million funding round in September. The company distinguishes itself in the competitive AI chip landscape by employing a unique architectural approach that does not rely on external high-bandwidth memory (HBM) chips. This design choice, leveraging on-chip static random-access memory (SRAM), mitigates the supply chain constraints currently impacting the global HBM market.
The LPU (Language Processing Unit) architecture, while enhancing inference speed for applications like chatbots, currently presents limitations regarding the maximum size of AI models that can be efficiently served. Groq’s primary competitor utilizing a similar architectural philosophy is Cerebras Systems, which has reportedly commenced preparations for an initial public offering (IPO) as early as next year. Both companies have strategically secured substantial contracts in the Middle Eastern market.
Nvidia’s investments in AI firms span the entire AI ecosystem, ranging from large language model developers such as OpenAI and xAI to “neoclouds” like Lambda and CoreWeave, which specialize in AI services and compete with its Big Tech customers. Nvidia has also invested in chipmakers Intel and Enfabrica. The company made a failed attempt around 2020 to acquire British chip architecture designer Arm Ltd. Nvidia’s wide-ranging investments — many of them in its own customers — have led to accusations that it’s involved in circular financing schemes reminiscent of the dot-com bubble. The company has vehemently denied those claims.

This deal follows a familiar pattern in recent years where the world’s biggest technology firms pay large sums in deals with promising startups to take their technology and talent but stop short of formally acquiring the target.
- A great example of that was Meta which in June invested ~$14.3 billion in Scale AI for a 49% stake in the company. That move valued the startup at around $29 billion. As part of that deal, 28 year old Alexandr Wang resigned as CEO of Scale AI to become Meta’s first-ever Chief AI Officer. He will remain on Scale AI’s board of directors. Wang’s team at the new “superintelligence” lab is tasked with building advanced AI systems that can surpass human-level intelligence.
- In a similar but smaller scale deal, Microsoft agreed to pay AI startup Inflection about $650 million in cash in an unusual arrangement that would allow Microsoft to use Inflection’s models and hire most of the startup’s staff including its co-founders, a person familiar with the matter told Reuters. The high-profile AI startup’s models will be available on Microsoft’s Azure cloud service, the source said. Inflection is using the licensing fee to pay Greylock, Dragoneer and some other investors, the source added, saying the investors will get a return of 1.5 times what they invested.
Bernstein analyst Stacy Rasgon wrote in a note to clients on Wednesday after Groq’s announcement:
“The Nvidia-Groq deal appears strategic in nature for Nvidia as they leverage their increasingly powerful balance sheet to maintain dominance in key areas…..Antitrust would seem to be the primary risk here, though structuring the deal as a non-exclusive license may keep the fiction of competition alive (even as Groq’s leadership and, we would presume, technical talent move over to Nvidia). Nvidia CEO Jensen Huang’s “relationship with the Trump administration appears among the strongest of the key U.S. tech companies.”

Nvidia CEO Jensen Huang recently dedicated a significant portion of his 2025 GTC 2025 conference keynote speech to emphasize that Nvidia intends to maintain its market dominance as the AI sector increasingly transitions its focus from model training to inference workloads. Huang delivered two major GTC keynotes in 2025: The primary annual conference held in San Jose, California, in March 2025 and a second GTC in Washington, D.C., in October 2025. At these events, he emphasized the rise of “reasoning AI” and “agentic AI” as the drivers for an unprecedented 100x surge in demand for inference computing in just a couple of years. Huang announced that the new Blackwell system, designed as a “thinking machine” for reasoning, was in full production and optimized for both training and large-scale inference workloads.
Huang shared a vision of moving from traditional data centers to “AI factories“—ultra-high-performance computing environments designed specifically to generate intelligence at scale, positioning investment in Nvidia’s infrastructure as an economic necessity.

Ookla: FWA Speed Test Results for big 3 U.S. Carriers & Wireless Connectivity Performance at Busy Airports
Ookla just released two new reports based on Speedtest Intelligence data, revealing critical shifts in how Americans connect to the Internet- from their homes and from the country’s 50 busiest airports.
Key findings from the first report:
- T-Mobile, AT&T and Verizon — adding 1.04 million new subscribers in Q3 2025 bringing the total number of FWA customers to 14.7 million, which is slightly more than 12.5% of the 117.4 million U.S. households with broadband, according to the U.S. Census Bureau’s 2024 American Community Survey.
- T-Mobile, Verizon and AT&T all experienced declines in both their median download and upload speeds during Q2 2025 and Q3 2025.
- T-Mobile is the FWA speed leader with median download speed of 209.06 Mbps for Q3 2025, which is approximately double that of AT&T’s median download speed of 104.63 Mbps in the same quarter.
- AT&T and T-Mobile customers in the 10th percentile of users are experiencing speed declines during peak hours in the late afternoon and evening. Verizon subscribers in the 10th percentile don’t have the same sorts of declines, indicating the operator’s enforcement of speed caps may be helping it deliver a more consistent experience to those customers.
- AT&T Internet Air’s latency is higher than its peers but it’s improving. AT&T’s median multi-server latency is ~ 67 milliseconds, “consistently higher” than Verizon (54 ms) and T-Mobile (50 ms) but a notable improvement from 78 ms in Q3 2024.
Separately, the analysts at New Street Research estimated AT&T, T-Mobile and Verizon can currently support up to 32 million FWA customers and they have already added nearly 50% of that number. Operators could potentially increase that load to 36 million following the Federal Communications Commission’s (FCC) upper C-Band auction.

Ookla’s second report analyzes cellular and Wi-Fi performance across the top 50 U.S. airports by passengers. Key findings:
- Cellular network providers had a faster median download speed than Wi-Fi in most airports and more than twice as fast on average. The overall median download speed for cellular was 219.24 Mbps. Note that 5G/4G splits were not explicitly examined.
- Verizon was fastest in the most airports comparing among all mobile providers and airport Wi-Fi including ties.
- Airport Wi-Fi was faster than mobile networks in just over one-third of head-to-head comparisons (including ties), and faster than all mobile providers in five airports.
- Older Wi-Fi technologies may be holding back internet speed in airports with 72.9% of Speedtest samples on Wi-Fi 5 and older generation versus 46.0% in the U.S. overall.
Wi-Fi was faster than any mobile provider in these five airports:
- Cincinnati/Northern Kentucky International
- San Francisco International
- Orlando International
- Hartsfield–Jackson Atlanta International
- Baltimore/Washington International (tie)
Wi-Fi is better by the Bay:
As shown in Wi-Fi’s fastest five airports, Oakland International and Norman Y. Mineta San José International made that list. Rounding out the Bay Area airportstrio, the Wi-Fi speed in San Francisco International comfortably topped the mobile providers.
| Airport | AT&T | T-Mobile | Verizon | Airport Wi-Fi |
| Oakland International | 229.70 | 28.58 | 103.90 | 194.23 |
| Norman Y. Mineta San José International | 103.83 | 211.40 | 251.06 | 176.59 |
| San Francisco International (SFO) | 67.07 | 92.91 | 100.56 | 169.51 |
SFO was the only airport in Ookla’s analysis with Speedtest samples using the 6 GHz band. This was on Wi-Fi 6E – too soon to expect Wi-Fi 7 in airports – with a median download speed of 364.74 Mbps (also remarkable were the median upload speed of 426.04 Mbps and an 8 ms multi-server latency).

Highlights of ITU Global Connectivity Report 2025 and the Baku Action Plan
The ITU Global Connectivity Report 2025, released at the conclusion of the World Telecommunication Development Conference (WTDC-25) in Baku, Azerbaijan, delivers a comprehensive assessment of how global connectivity has evolved from a scarce asset in 1994 into a foundational layer of the digital economy and everyday life, with close to 6 billion users projected to be online by 2025. Its analytical framework is anchored in the policy objective of achieving universal and meaningful connectivity (UMC), structured across six interdependent dimensions: Quality, Availability, Affordability, Devices, Skills, and Security.
The report underscores the socio‑economic gains associated with large‑scale digital transformation, including enhanced productivity, innovation, and service delivery across sectors. At the same time, it emphasizes that progress is constrained by persistent digital divides along income, gender, age, and geographic lines, as well as by escalating exposure to online harms, misinformation, and non‑trivial environmental externalities from ICT infrastructure and usage.
It suggests the era of easy, organic network expansion is over. While 74% of the world is now online, the curve is flattening, and the remaining deficits are structural rather than merely about access.
With an estimated 2.2 billion people still offline, ITU Member States (194) agreed this week on the Baku Action Plan—a four-year roadmap to 2029 designed to close these persistent divides.
The report provides detailed analysis of structural barriers to universal and meaningful connectivity (UMC), notably high connectivity and device costs, gaps in digital skills, and constrained access to appropriate end‑user devices. It translates this analysis into evidence‑based policy guidance focused on regulatory coherence, targeted affordability interventions, and demand‑side enablers to ensure that connectivity translates into effective and inclusive digital usage.
From a network engineering and infrastructure perspective, the report highlights the critical role of resilient, high‑capacity backbones, including submarine cable systems and satellite constellations, as strategic layers of the global connectivity fabric. It stresses the need for coordinated investment, robust redundancy and security models, and integrated planning across terrestrial, subsea, and space‑based networks to support UMC objectives.
The report identifies high service and device costs, insufficient digital skills, and limited device availability as key barriers, and provides evidence‑based policy guidance on regulatory coherence, affordability, and demand‑side enablers. It emphasizes the importance of resilient infrastructure such as submarine cables and satellites, along with stronger national data ecosystems, to support inclusive connectivity strategies and informed digital policy‑making.
Finally, the report calls for strengthening national data ecosystems—covering data collection, governance, sharing, and analytics—as a prerequisite for effective digital inclusion strategies and evidence‑driven policy‑making. It positions mature data capabilities and coherent digital governance frameworks as key enablers for monitoring progress across the six UMC dimensions and for calibrating telecom and ICT policy in line with evolving market and technology dynamics.
