Verizon once again delays 5G Standalone (SA) commercial service
Like AT&T, Verizon has promised 5G standalone (SA) core network for a very long time. The mostly wireless U.S. carrier initially said it would launch standalone 5G in 2020. Some in the industry thought it did so in 2022. But the company said the technology ‘is in testing now’ and is still not available commercially.
“We have it in trials only at this point. We don’t have it commercially available for our customers,” Verizon’s chief networking executive, Joe Russo, said on a podcast last month hosted by Recon Analytics. “So more to come in the next several months as Verizon will be entering the standalone core game.”
“It is absolutely a capability that we think will be another enabler to new use cases. But … the reliability and performance of Verizon’s network is what we stand for, and I don’t put technology out into the network that is a step back. It has to be a step forward. And all of the data that I see – both internal testing and with external testing that happens out there in the market – tells me that SA [standalone] needs a little bit more time.”
“We’re doing significant developing and testing to make sure that both the data session and the voice sessions in a standalone world are as good or better than what you would expect in our 4G network today. So we see that in the next several months we’re going to get there, but it was not my goal to be first in deploying standalone. It’s my goal to be best in deploying standalone.”
……………………………………………………………………………………………………………………………..
Verizon spokesperson Kevin King clarified that “we have commercial traffic running on our 5G non standalone core. That is what we announced earlier in the year. Joe was referring to our 5G standalone core which is in testing now.”
That cop-out was contradicted by a statement made during a webinar for analysts on September 29th, which was obtained by Light Reading. “People talk about the standalone core. Just terminology-wise, that’s the 5G core essentially. If you guys have read the stuff we’ve said publicly, certainly we serve some customers on portions of our 5G core,” said Mike Haberman, Verizon’s SVP of strategy and transformation, And then we have some internal stuff going on with other functionality on the core. We’re in the process of rolling out (5G SA) in a very smart fashion.”
“Here’s the deal: When you go to the standalone core, you can’t aggregate your LTE carriers. With the non standalone core I’m aggregating together both 5G and 4G. So when you go standalone you start to bifurcate the spectrum. So that’s the impact to the RAN [radio access network]. So you better be sure that your mobile [customer] distribution, where they are geography, makes sense. Or what will happen is those customers will experience a lower service level. No good. We want to be careful of that. So that’s why, when you do the standalone core, you have to pay very close attention to your radio access network because they are directly attached.”
On April 27th Verizon issued a press release describing the benefits of 5G standalone (SA) technology and how it’s “what sets Verizon apart.” However, the release doesn’t specifically say that Verizon launched the technology. That despite Verizon last year announced it had begun moving traffic onto its new 5G core, which supports both the non standalone (NSA) and standalone (SA) versions of the technology.
Last year, Mobile World Live reported that Verizon was migrating “commercial traffic onto SA 5G core.” The article cited an unnamed Verizon representative. Mobile World Live also reported that Ericsson, Casa Systems, Oracle and Nokia supply Verizon’s 5G core.
Dell’Oro Group, in January 2023, listed Verizon among the few North American wireless providers that had commercially launched the technology.
“This is a moving target,” Recon Analytics analyst Roger Entner told Light Reading. But Entner said Verizon’s position on the standalone version of 5G makes sense. “The benefits you can get today from standalone are limited.”
–>This author totally disagrees with Mr. Entner, because TRUE 5G=5G SA. IN OTHER WORDS, ALL OF THE 3GPP DEFINED 5G FEATURES REQUIRE 5G SA! That includes 5G security and network slicing.
…………………………………………………………………………………………………………………………………
Light Reading’s Mike Dano wrote:
Verizon now appears to be roughly three years behind its initial standalone 5G rollout plans. In the summer of 2020, Verizon said it would begin moving traffic onto its standalone 5G core “in the second half of 2020 with full commercialization in 2021.”
Then, in early 2022, Verizon CTO Kyle Malady suggested that the operator would begin moving some of its fixed wireless access (FWA) traffic onto its standalone 5G core by June of that year. He also said at the time that Verizon would start putting smartphone traffic onto that core in 2023.
………………………………………………………………………………………………………….
T-Mobile US and Dish Wireless are the only two 5G carriers that have launched commercial 5G SA. AT&T has made a lot of noise about it’s 5G SA plans but has yet to launch.
AT&T’s chief networking executive, Chris Sambar, wrote in a September 29th blog post that AT&T was moving some customers to standalone 5G. “Many of the newest mobile devices are ready for 5G standalone, and we continue to move thousands of customers every day. We also recently launched AT&T Internet Air home fixed wireless service, and from the start, this product rides on standalone 5G.”

SpaceX has majority of all satellites in orbit; Starlink achieves cash-flow breakeven
SpaceX accounts for roughly one-half of all orbital space launches around the world, and it’s growing its launch frequency. It also has a majority of all the satellites in orbit around the planet. This Thursday, majority owner & CEO Elon Musk tweeted, “Excited to announce that SpaceX Starlink has achieved breakeven cash flow! Starlink (a SpaceX subsidiary) is also now a majority of all active satellites and will have launched a majority of all satellites cumulatively from Earth by next year.”
There are some 5,000 Starlink satellites in orbit. Starlink satellites are small, lower-cost satellites built by SpaceX that deliver high-speed, space-based internet service to customers on Earth. Starlink can cost about $120 a month and there is some hardware to buy as well.
Starlink ended 2022 with roughly 1 million subscribers. The subscriber count now isn’t known, but it could be approaching 2 million users based on prior growth rates. SpaceX didn’t return a request for comment.
In 2021, Musk said SpaceX would spin off and take Starlink public once its cash flow was reasonably predictable.

Starlink has been in the spotlight since last year as it helps provide Ukraine with satellite communications key to its war efforts against Russia.
Last month, Musk said Starlink will support communication links in Gaza with “internationally recognized aid organizations” after a telephone and internet blackout isolated people in the Gaza Strip from the world and from each other.
Musk has sought to establish the Starlink business unit as a crucial source of revenue to fund SpaceX’s more capital-intensive projects such as its next-generation Starship, a giant reusable rocket the company intends to fly to the moon for NASA within the next decade.
Starlink posted a more than six-fold surge in revenue last year to $1.4 billion, but fell short of targets set by Musk, the Wall Street Journal reported in September, citing documents.
SpaceX is valued at about $150 billion and is one of the most valuable private companies in the world.

Verizon transports 1.2 terabytes per second of data across a single wavelength
Verizon has upgraded its optical to electrical conversion cards to send data at speeds of 1.2 Tbps on a single wavelength through the carrier’s live production network. The trials demonstrated increased reliability and overall capacity as well, Verizon said.
The trials, which were conducted in metro Long Island, N.Y., were in partnership with Cisco and included technology from Acacia, as well. They utilized Cisco’s NCS 1014 transceiver shelf and Acacia’s Coherent Interconnect Module (CIM 8). Verizon said the module features silicon semiconductor chips with 5nm complementary metal-oxide semiconductor (CMOS) digital processing and 140 Gbaud silicon photonics using 3D packaging technology. In short, digital processing capabilities and transistor density both are increased.
Verizon said that it transmitted a 1.0 Tbps single wavelength through the Cisco NCS 20000 line system for more than 205 km. It traversed 14 fiber central offices (COs). The carrier said this is significant because progressive filtering and signal-to-noise degradation impact wavelengths as they pass through each CO. The trials also featured 800 Gbps transmission for 305 km through 20 COs — and a 1.2 Tbps wavelength that traversed three offices.
“We have bet big on fiber. Not only does it provide an award-winning broadband experience for consumers and enterprises, it also serves as the backbone of our wireless network. As we continue to see customers using more data in more varied ways, it is critical we continue to stay ahead of our customers’ demands by using the resources we have most efficiently,” said Adam Koeppe, SVP of Technology Planning at Verizon.

In addition to increasing data rates, the new optics technology from Cisco reduces the need for regeneration of the light signal (conversion to electrical and back to optical signals) along the path by compensating for the degradation of the light signal traveling through the fiber cable. This adds reliability and leads to a reduced cost per bit operating expense for more efficient network management.
Bill Gartner, senior vice president and general manager of Cisco Optical Systems and Optics, added, “This trial demonstrates our commitment to continuous innovation aimed at increasing wavelength capacity and reducing costs. The Verizon infrastructure built with the Cisco NCS 2000 open line system supports multiple generations of optics, thus protecting investments as technology evolves.”
In March, Windstream Wholesale said that it sent a 1 Tbps wave across its Converged Optical Network (ICON) between Dallas and Tulsa, a distance of 541 km.

Tutorial: Utilizing Containers for Cloud-Native and Elastic SBCs
by Bhupen Chauhan (edited by Alan J Weissberger)
Introduction:
A recent advancement in Session Border Controllers (SBCs) involves moving them to the cloud and utilizing elasticity. The use of Containers (defined below) intensifies this change even more. SBC solutions are essential for businesses. Service providers depend on Voice over IP (VoIP), because they provide security, interoperability, quality, and compliance in their communication infrastructure. We’ll delve further into the world of Cloud Native/Elastic SBCs using containers in this post.
What is a SBC?
A Session Border Controller (SBC) is a specialized hardware device or software program that controls how phone calls are answered, carried out, and ended as VoIP. They act as gatekeepers between internal and external networks, managing the media streams and signals necessary for establishing, carrying out, and terminating calls.
A SBC establishes and keeps track of each session’s quality of service (QoS) state, guaranteeing calls must be answered correctly, and urgent calls take precedence over all other calls. Additionally, an SBC can act as a firewall for session traffic by enforcing its QoS policies and recognizing particular inbound threats to the communication environment.
SBC’s Significance in Communications:
By providing security, guaranteeing interoperability, and enabling the effective use of network resources, SBCs strengthen communication networks. Here are several reasons to have Session Border Controller in VoIP Phone System and protect IP communications, defending against intrusions and offering essential functions, including:
- Security: An SBC’s most important responsibility is to defend the network against hostile assaults, including fraud, eavesdropping, and denial of service (DoS) attacks. They add a layer of security by concealing the network topology.
- Quality of Service (QoS): SBCs ensure that voice calls have the capacity and resources to remain high-quality by prioritizing voice traffic over other kinds of traffic.
- Interoperability: SBCs provide smooth communication between various devices, protocols, and signaling in IP networks by offering the required protocol translations.
- NAT Traversal: VoIP communication may encounter problems due to Network Address Translation (NAT). By fixing NAT traversal issues, SBCs guarantee reliable and continuous communications.
- Call Routing and Policy Enforcement: SBCs effectively route calls according to rules and specifications. They can also control bandwidth usage and implement various payment methods.
- Regulatory Compliance: Communication service providers are required in some areas to offer the ability to intercept communications legally. SBCs help VoIP service providers in fulfilling these kinds of legal obligations.
- Media services: Comprise functions like tone production, DTMF (dual-tone multi-frequency) interworking, and transcoding (changing one codec to another).
SBCs are essential to today’s communications environment, particularly regarding IP-based voice and video communications. Cloud-based and elastic SBCs will play a more significant role as communications change and more services go to the cloud. Now, we will together understand the concept of Cloud Native and Elastic SBCs.
What are Cloud Native and Elastic SBCs?
A strategy for developing and executing programs that takes advantage of the cloud computing concept is known as cloud-native. Conversely, Elastic SBCs describe a system’s capacity to adjust automatically to variations in workload by allocating and releasing resources.
Traditional SBCs and Cloud Native/Elastic SBCs are different as we now explain.
Traditional SBCs vs. Cloud Native/Elastic SBCs:
Traditional SBCs lack flexibility and are usually hardware-based. They might be expensive and difficult to expand or change. In comparison, Cloud Native/Elastic SBCs are highly adaptable. They provide cost-effectiveness and agility by effortlessly scaling up or down in response to demand.
Elasticity’s Function in Communication Services:
Elasticity guarantees continuous communication services that can adjust to heavy demands, particularly during peak hours. It implies that networks may scale resources without human intervention, ensuring service quality without taxing the infrastructure or adding needless expenses.
………………………………………………………………………………………………………………………………………
What are Containers?
Containers are small, independent, executable software packages containing all the necessary components to run a piece of software, guaranteeing that it performs consistently in various computing settings.
Function of Containers in the Modern Applications Deployment:
Containers offer an unequaled level of consistency and speed, revolutionizing how programs are delivered. They contain an application and all its dependencies, guaranteeing that it functions the same everywhere it is deployed.
Kubernetes and Docker:
Docker technology creates, transports, and operates applications inside containers. Meanwhile, Kubernetes’s container orchestration technology ensures that massive container deployments are effectively scaled and managed.
The Research and Markets predicts the global Kubernetes market is anticipated to expand significantly, rising from USD 1.8 billion in 2022 to USD 7.8 billion by 2030, with a spectacular Compound Annual Growth Rate (CAGR) of 23.4%
Use of Containers in SBCs:
SBCs benefit from unrivaled scalability, flexibility, and agility thanks to containers. They enable rapid deployments, guarantee consistency across many environments, and dramatically cut overall overheads—financially and in terms of time. Using Containers involves:
- Individual micro-services package and deploy using containers such as Docker. It guarantees scalability, isolation, and effective resource use.
- It can easily update services, rolled back, and versioned.
Architectural Considerations for Creating Cloud-Native Applications:
Scalability, Redundancy, Resilience, and Performance considerations are crucial when constructing Cloud Native/Elastic SBCs with containers. Architectures must be modular, and facilities must be made for smooth upgrades and patches that don’t interfere with running services. The following architectural factors should be taken into account while creating and deploying Cloud Native/Elastic SBCs using containers:
Disentanglement of Elements:
- Conventional SBCs frequently integrate several features into a single monolithic system.
- Micro-services design, in which every function (signaling, media processing, transcoding, security, etc.) is a separate, independent service, is the best way to create cloud-native SBCs.
Coordination:
- Containerized SBC micro-services can be managed and orchestrated by tools such as Kubernetes, which guarantees their efficient scheduling, scaling, and maintenance.
- Consider putting service mesh technologies into practice for enhanced traffic management and security.
State Administration:
- Active call sessions require careful management.
- Consider utilizing state full sets in Kubernetes or distributed databases to maintain a session state.
High Redundancy and Availability:
- Should guarantee redundancy over several zones or regions Via cloud-native design.
- Incorporate self-healing procedures and health checks to ensure uninterrupted service availability.
Converting SBCs to a containerized, cloud-native architecture has benefits for maintainability, scalability, and flexibility. However, careful architectural considerations are necessary to guarantee cost-effectiveness, security, and performance.
Containers Networking for Real-Time Communication:
The networking element of containers is essential in the area of real-time communication. It guarantees seamless switching between media streams, satisfies low-latency specifications, and ensures that Quality of Service (QoS) standards.
Elastic and Cloud Native SBC Security and Compliance:
SBCs play a crucial role in addressing security. Strong security measures are required for Cloud Native/Elastic SBCs to thwart threats, prevent unwanted access, and guarantee data privacy. They must also adhere to industry norms and laws to ensure reliable communication connections.
Prospects for the Future and the Changing Scene for Cloud Native SBCs:
SBCs will likely interact more deeply with cloud ecosystems in the future, utilizing AI and machine learning to provide more innovative and adaptive features. To support developing IoT and 5G use cases, edge computing may also play a more significant part in Cloud Native SBCs.
Conclusions:
A significant improvement in the evolution of network security and telecommunications has been realized cloud-native and elastic principles and the power of containers. This new paradigm is poised to completely reshape communication networks in the future since it provides agility, scalability, and efficiency. As we embrace containerization and the cloud, the possibilities are endless, opening the prospect of a more efficient, safe, and networked world.

Charter Communications adds broadband subs and raises CAPEX forecast
Cableco Charter Communications added 63,000 broadband internet subscribers in the third quarter. Net adds in new markets hit 31,000 in the third quarter, accelerating from 26,000 last quarter. A note from New Street Research said the company passed fewer homes in new markets than expected, “and so the pace of penetration growth is tracking ahead of expectations.”
Charter’s third-quarter revenue of $13.6 billion grew by 0.2% year-over-year, driven by residential internet revenue growth of 3.7%, residential mobile service revenue growth of 33.8% and other revenue growth of 28.8%, mostly driven by higher mobile device sales.
Free cash flow of $1.1 billion decreased from $1.5 billion in the prior year, due to higher capital expenditures, mostly driven by Charter’s network evolution and expansion initiatives.
As of September, Charter had a total of 32.2 million residential and SMB customer relationships, excluding mobile-only relationships.
“We continue to make significant progress against the multi-year strategic initiatives we outlined last year,” said Chris Winfrey, President and CEO of Charter. “These initiatives drive continuing improvements in the quality of our products, and when combined with our customer-friendly pricing and packaging and high-quality service, will drive significant, long-term growth in shareholder value.”
…………………………………………………………………………………………………………………….
On its earnings call, CEO Winfrey said that “given the greater subsidized rural passings and construction opportunity,” Charter may even look to partially fund those new markets by “very modestly slowing our network evolution plan” — which includes upgrades to its hybrid fiber-coaxial footprint.
Winfrey said Charter expects to add approximately 300,000 new subsidized rural (NSR) passings in 2023 and to accelerate that pace in 2024. In the third quarter, 78,000 rural passings were activated. He added that Charter is ahead with its Rural Digital Opportunity Fund (RDOF) builds and “will end up with more (rural) passings than originally expected.”
However, NSR said Charter’s results in core markets were “disappointing,” with adds of 47,000 way below their estimate of 79,000. While NSR expected stabilization in pressure from fixed wireless access (FWA), Charter continues to see some impact from FWA competitors in the lower usage and price sensitive customer segments of its residential and SMB businesses.
Charter is raising its capital-expenditures (CAPEX) forecast for the year as it pours billions back into upgrading its network and its Xumo business. The company now expects to spend about $7.2 billion in CapEx, up from prior guidance of $6.5 billion to $6.8 billion. That excludes line-extension CapEx, which is still expected to be about $4 billion for the year. The $7.2 billion will be put to work upgrading and maintaining the cable company’s network. Some of it will also go toward sending Xumo stream boxes to customers. Xumo is a joint venture between Charter and Comcast that offers free ad-supported streaming TV. Charter shares fall 6%.

Huawei reports 1% YoY revenue growth in 3Q-2023; smartphone sales increase in China
Huawei reported a flat third quarter, with sales of 145.7 billion Chinese yuan ($19.9 billion), up just 1% over last year and a net profit margin of 16.0%. The Shenzhen based telecom equipment and mobile phone vendor said the profit margin had been boosted by the latest tranche from the sale of the Honor handset assets three years ago. It said improved efficiencies and optimized sales and product strategies had also had a positive impact on profitability.
“The company’s performance is in line with forecast,” said Ken Hu, Huawei’s Rotating Chairman. “I’d like to thank our customers and partners for their ongoing trust and support. Moving forward, we will continue to increase our investment in R&D to make the most of our business portfolio and take the competitiveness of our products and services to new heights. As always, our goal is to create greater value for our customers, partners, and society.”
Huawei reported growth in the consumer business unit and “strong growth” in the new digital power and cloud businesses, but the company was silent on its carrier equipment unit, its largest, suggesting it has also been hit by the decline in operator spending.
Huawei smartphone summary:
Huawei was the fastest-growing smartphone maker in China in the third quarter after the company released a smartphone with a surprisingly advanced chip inside.
- In September, Huawei launched the Mate 60 Pro in China. It’s equipped with an advanced chip and 5G connectivity, technology that U.S. sanctions had been designed to stop Huawei getting its hands on.
- The success of that device helped Huawei’s smartphone sales in China grow 37% year on year, according to a report from Counterpoint Research.
- Sales of Honor, the largest smartphone maker by market share, rose just 3% year on year. Vivo, Oppo and Apple all saw double-digit declines, according to Counterpoint Research.

Google Fiber planning 20 Gig symmetrical service via Nokia’s 25G-PON system
Google Fiber is planning to rollout a symmetrical 20G b/sec service for select residential and business customers by the end of this year. It will use Nokia’s 25G-PON system for this new service.
Nokia’s 25G PON solution will allow Google Fiber to provide broadband speeds up to 10x faster than what most fiber networks can deliver today. GFiber Labs is using Nokia’s solution to deliver 20 Gig services to the University of Missouri-Kansas City (UMKC) and United Way of Utah County, with plans to expand to select residential customers by the end of the year.
Liz Hsu, Senior Director, Product & Billing at Google Fiber, said: “The age of multi-gig broadband services is here and we’re committed to ensuring all of our customers can benefit from the incredible potential it brings. We believe investments in advanced network technologies like Nokia’s 25G PON solution will help catalyze change, drive innovation and revolutionize the user experience. We’re thrilled to be working with Nokia to move our industry and customers forward.”
Geert Heyninck, General Manager of Broadband Networks at Nokia, said: “It’s an exciting time to be a Google Fiber customer as we work to help them usher in a new era of connectivity that’s capable of delivering lightning fast 20 gigabit services. With our 25G PON solution Google Fiber can reuse its existing fiber network to quickly and cost effectively deliver the next generation of gigabit services to their customers. We’re proud to continue supporting Google Fiber on its quest to build the foundation of tomorrow’s internet.”
Julie Kunstler, Chief Analyst, Broadband Access Intelligence Service at Omdia, said: “This announcement highlights the momentum we are starting to see for 25G PON. With a robust ecosystem, 25G PON can be a natural fit for those operators that want to pursue higher-revenue customers and applications. Because you can use the same underlying infrastructure as FTTH, this means more revenues without expensive new network builds or additional operational costs.”
Nick Saporito, head of product at Google Fiber, told Fierce Telecom that the company has been trialing the 20-gig service in “many markets” for almost a year. Additional residential test ers are “in the pipeline,” he said.
Asked why Google Fiber is jumping from its current top tier 8-gig offering all the way to 20-gigs, Saporito said “We definitely see a need for this. This is sort of a very early adopter product. This isn’t going to be a GA [general availability] product from Google Fiber where we just make it broadly available like we’re doing with 5-gig and 8-gig. This is going to be a bit of an invite-only opportunity for our early adopters.”
To be clear, Google Fiber’s forthcoming offering won’t be the fastest available in the country nor is the company the first to break the 10G speed barrier. EPB, a local provider in Tennessee, launched a symmetrical 25-gig service in August 2022. It, too, is using Nokia’s 25G kit.
But the move is significant as Google Fiber seems to be the largest operator to make such a play in earnest thus far. Frontier Communications previously said it is working with Nokia on 25G trials, but has yet to announce plans for a commercial service beyond its current 5-gig offering.
Stefaan Vanhastel, VP of Innovation for Fixed Networks at Nokia, told Fierce that Google Fiber was already using the company’s XGS-PON gear, which is based on its upgradable Quillion chipset. So, all the operator needs to do to get to 25G is plug in a new optical module and replace the optical network terminal on the end-user side.
He noted that 25G uses different wavelengths than GPON and XGS-PON, meaning all three technologies can coexist on the same network.
Vanhastel said globally Nokia has around eight or nine 25-gig operators, most of whom are squarely focused on enterprises services. Thus, Google Fiber’s desire to serve both residential and enterprise use cases is special. “To me that’s really exciting, because it’s going to be really interesting to see those multi-gig users how they’re using the service, what they’re doing,” he said. “You build a pipe, someone’s going to try to find a way to fill it.”
Saporito declined to name the markets where its symmetrical 20-gig service will initially be available (though Kansas City seems like a safe bet based on the trial locations). However, he said the operator does have broader plans to make the service available “in most, if not all, of our markets” eventually.

Nokia 25G PON details:
As 25GPON will drive new and exciting applications, GFiber’s introduction of Nokia’s Lightspan and Altiplano solution increases service agility with operational efficiency. The fiber access node supports multiple fiber technologies including GPON, XGS-PON, 25GS-PON and Point-to-Point Ethernet to deliver a wide range of services with the best fit technology.

Verizon, T-Mobile and AT&T brag about C-band 5G coverage and FWA
Verizon says it has approximtely 222 million people covered with its mid-band C-band network, [1.] a figure the company hopes to increase to 250 million by the end of next year. “C-band is a game change for our business,” CEO Hans Vestberg said on the telco’s 3rd quarter earnings call. “Our network is winning.”
Note 1. C-band sits between the two Wi-Fi bands, which are at 2.4GHz and 5GHz. It’s slightly above and very similar to the 2.6GHz band that Clearwire and then Sprint used for 4G starting in 2007, and which T-Mobile currently uses for mid-band 5G. And it adjoins CBRS, a band from 3.55 to 3.7GHz that’s currently being deployed for 4G. ITU-R divided C-band into three chunks, referred to as band n77, band n78, and band n79.

Verizon officials said the company is using the capacity in its mid-band 5G network to pursue opportunities like fixed wireless access (FWA) and private wireless networks. “We see demand for the product continuing to grow,” Vestberg said of Verizon’s private wireless network offerings. He added that Verizon is working to transition its private wireless customers from pilots to commercial deployments. He also said the company is growing its ecosystem of suppliers for that business.

T-Mobile announced Tuesday it now covers 300 million people with its 2.5GHz mid-band network, reaching that goal three months earlier than the company had planned. T-Mobile’s overall 5G footprint has expanded as well, now covering more than 330 million people or 98% of the population.
“We have been leaders in the 5G era from the start, deploying the largest, fastest, most awarded and most advanced 5G network in the country faster than anyone else,” said Ulf Ewaldsson, President of Technology at T-Mobile. “While the other guys are playing catch-up, finally beginning to build out their mid-band 5G networks, we are maintaining our lead and will continue offering customers the best network – paired with the best value – for years to come.”
“T-Mobile’s turnaround story is incredible, going from network underdog a decade ago to the undeniable network leader today,” said Anshel Sag, Principal Analyst at Moor Insights and Strategy. “T-Mobile has not only built out a robust 5G network with unmatched coverage and capacity, but the Un-carrier is also leading the way in rolling out new capabilities that will unlock the true promise of 5G.”

Last week, AT&T said it ended the third quarter covering 190 million subscribers for its mid-band 5G network, and said it remains on track to cover 200 million by the end of the year. On the telco’s 3-2023 earnings call, CEO John Stankey said, “we continue to enhance the largest wireless network in North America and expand the nation’s most reliable 5G network. It’s no surprise that when you combine our high-value customer growth and rising revenues per user, we continue to grow profits in our wireless business.”
Regarding FWA, Stankey touted the company’s Internet Air offering. “We have no issues selling Internet Air into the business segment. It’s a really attractive thing for us to do. It’s a really helpful product on a number of different fronts. It meets a particular need.

Telecom layoffs continue unabated as AT&T leads the pack – a growth engine with only 1% YoY growth?
As we have repeatedly stated, the entire telecom industry is in a funk and the 2024 outlook is looks just as gloomy as this year. MTN claims that telecom is a zero growth industry (see References below) and that certainly seems to be true. Let’s start with AT&T – the largest telco in the U.S. with 229.2M wireless subscribers as of Q2-2022.
In the first nine months of 2023, AT&T has shed 10,200 employees, including nearly 4,000 in the recent third quarter alone. AT&T cut many more jobs – 39,700 in total – in 2022 when it was in the process of spinning out Warner Media to Warner Brothers Discovery (the deal closed on April 8, 2022).
AT&T’s CEO told reporters last week that the U.S. based teclo plans to reduce costs by another $2 billion over the next three years. That’s after Stankey boasted that the company has cut costs by $6 billion in the last three and in an “inflationary environment.”
AT&T is hardly a growth company and has tons of debt. In the 3rd quarter of 2023, AT&T reported revenues of $30.4 billion, up only 1% year over year. Yet Stankey had the audacity to say in a press release, “Our investments in best-in-class 5G and fiber connectivity are fueling our growth engine. We’re gaining profitable customer relationships and becoming more efficient. This is powering our strong business performance.”
Today, LightReading announced the departure of a key AT&T executive. Jason Inskeep, previously the senior assistant VP for AT&T’s 5G Center of Excellence and focusing on the operator’s work in private wireless networking and edge computing, recently left the company for a senior director position at consulting firm Slalom.
Iain Morris of LightReading wrote on October 20th, “The future AT&T is conceivably a cohort of antenna-carrying robots, some AI that writes code and Stankey with his feet up on the table, providing the only whiff of humanity.”
AT&T is not the only U.S. telco reducing its workforce. Earlier this year, T-Mobile announced that it will be laying off ~5,000 workers or around 7% of its workforce. This latest job cutting move will primarily impact employees in corporate, back-office, and technology roles, while those in retail or customer care positions will not be affected.

Network Equipment Vendors Layoffs and Gloomy Outlook:
Last week, Nokia said the company plans to cut at least 9,000 jobs and as many as 14,000 over the next three years. That’s mainly due to weak 5G equipment demand. Nokia CEO Pekka Lundmark told reporters that Nokia’s sales have plummeted in North America (sales were down 40%) and that India’s 5G rollout is now slowing down as expected.
Over the next three years, his latest target is to reduce annual costs by between €800 million (US$843 million) and €1.2 billion ($1.3 billion). It’s a move that will reduce Nokia’s headcount by at least 9,000 roles from its current level of roughly 86,000. And at the upper end of the range, it will see an exodus of 14,000 employees, more than 16% of the total.
Ericsson CEO Borje Ekholm cautioned of persistent macroeconomic uncertainty into 2024 which it expects will impact customers’ investment ability, as the wireless network equipment vendor reported a year-on-year net loss of SEK30.5 billion ($2.8 billion) from net income of SEK5.4 billion in Q2 2022, due to a SEK32 billion charge related to the acquisition of cloud company Vonage in 2022. In February, Reuters reported that Ericsson will lay off 8,500 employees globally as part of its plan to cut costs, a memo sent to employees.

Semiconductor Layoffs:
Wireless network chip maker Qualcomm is slashing 1,258 jobs in California, including nearly 200 in the Bay Area, in the latest tech layoffs to hit the region. Qualcomm said in state filings that it will lay off approximately 194 workers in its Santa Clara offices and another 1,094 employees at its San Diego headquarters. The cuts are slated to begin Dec. 13th, based on a notice submitted to state officials this week. The job cuts represent roughly 2.5% of Qualcomm’s workforce and mark the second round of layoffs for the wireless semiconductor company this year.
The Qualcomm layoff news comes about a month after the company announced a deal with Apple to provide 5G chips through at least 2026. Qualcomm is also the chip supplier for the newly announced Meta Quest 3. It is only 1 of 2 companies that sell 5G end point silicon on the merchant market (Taiwan based MediaTek is the other one).
It’s not a pretty picture to say the least for telecom industry employees.
