U.S. Cellular has agreed to sell $1.02 billion worth of spectrum licenses to AT&T as part of its strategy to monetize its spectrum assets that were not included in an earlier $4.4 billion deal with T-Mobile. Reuters reports: Last month, U.S. Cellular agreed to sell select spectrum licenses for $1 billion to Verizon. It also signed deals with two other mobile network operators, but did not disclose the details. The latest agreement "adds a fourth mobile network operator, in addition to T-Mobile, to the list of those whose subscribers will benefit from the sale of our spectrum licenses," U.S. Cellular CEO Laurent Therivel said on Thursday. From a press release: Following this transaction, as well as those previously announced, UScellular will have reached definitive agreements to monetize approximately 55%, measured on a MHz-Pops basis, of the spectrum holdings (excluding mmWave) that were excluded from the proposed sale to T-Mobile, for a total consideration of approximately $2.02 billion. Including the proposed T-Mobile transaction, UScellular will have reached agreements to monetize approximately 70% of its total spectrum holdings (excluding mmWave), measured on a MHz-Pops basis.

"After our proposed sales, we will be left with 1.86 billion MHz-Pops of low and mid-band spectrum, as well as 17.2 billion MHz-Pops of mmWave spectrum, with the substantial majority of retained value in the C-band spectrum," [said Laurent C. Therivel, President and CEO]. "The C-band licenses have a number of attributes that we believe are favorable to their long-term value. First, our C-band licenses are positioned in an attractive mid-band frequency that can deliver outstanding speed and capacity. Second, there is a substantial 5G ecosystem of equipment vendors and existing infrastructure that uses C-band. Finally, they have a lengthy build-out timeline, with first and second build-out dates of 2029 and 2033, respectively. This provides ample time and optionality for us to either monetize or deploy the spectrum in the future. We will continue to look for ways to opportunistically monetize the C-band, as well as the other remaining spectrum."

Federal Communications Commission Chair Jessica Rosenworcel outlined a vision for universal connectivity last week that merges satellite and ground-based networks. The FCC recently became the first regulator to establish a framework for supplemental coverage from space (SCS). "Satellites may be in our skies, but they are the anchor tenant in our communications future," said Rosenworcel, calling for seamless integration of fiber, cellular, wireless, and satellite infrastructure into a unified network. The vision comes as the FCC's Affordable Connectivity Program recently ended due to funding depletion.

AT&T has signed a $1 billion multi-year deal with Corning to acquire fiber and connectivity solutions. Reuters reports: With the U.S. wireless market facing a slowdown, telecom companies such as AT&T and rival Verizon have doubled down on their high-speed internet businesses, an area that has long been dominated by broadband companies such as Comcast. Demand has also been growing for AT&T's plans that allow customers to combine its high-speed fiber data with its wireless phone service for a discount. In the third quarter, AT&T reported 28.3 million fiber passings, or the number of potential customer locations a fiber network passes by. It remains on track to pass more than 30 million fiber passings by the end of 2025.

San Francisco's Municipal Transportation Agency approved a $212 million contract with Hitachi Rail to modernize the Muni Metro system's outdated train control system, which currently uses floppy disks and wire loops. Government Technology reports: The software that runs the system is stored on floppy disks that are loaded each morning and an outdated type of communication using wire loops that are easily disrupted. It was expected to last for 20 to 25 years, according to Muni officials. It moves data more slowly than a wireless modem, they said. By late 2027 and into 2028, a new communications-based system, which employs Wi-Fi and cell signals to precisely track the locations of trains, will be installed by Hitachi, which will provide support services for 20 years under the agreement.

While the current train control system operates only on the Market Street subway and Central Subway, the new system will control Metro light rail trains on the system's surface lines as well. The Hitachi system is said to be five generations ahead of the current system, said Muni Director of Transit Julie Kirschbaum, who described it as the best train control system on the market.

An anonymous reader writes: T-Mobile and AT&T say US regulators should drop a plan to require unlocking of phones within 60 days of activation, claiming that locking phones to a carrier's network makes it possible to provide cheaper handsets to consumers. "If the Commission mandates a uniform unlocking policy, it is consumers -- not providers -- who stand to lose the most," T-Mobile alleged in an October 17 filing with the Federal Communications Commission. The proposed rule has support from consumer advocacy groups who say it will give users more choice and lower their costs.

T-Mobile has been criticized for locking phones for up to a year, which makes it impossible to use a phone on a rival's network. T-Mobile claims that with a 60-day unlocking rule, "consumers risk losing access to the benefits of free or heavily subsidized handsets because the proposal would force providers to reduce the line-up of their most compelling handset offers." If the proposed rule is enacted, "T-Mobile estimates that its prepaid customers, for example, would see subsidies reduced by 40 percent to 70 percent for both its lower and higher-end devices, such as the Moto G, Samsung A15, and iPhone 12," the carrier said. "A handset unlocking mandate would also leave providers little choice but to limit their handset offers to lower cost and often lesser performing handsets." In July, the FCC approved a Notice of Proposed Rulemaking (NPRM) for the unlocking policy in a 5-0 vote.

The FCC is proposing "to require all mobile wireless service providers to unlock handsets 60 days after a consumer's handset is activated with the provider, unless within the 60-day period the service provider determines the handset was purchased through fraud."

An anonymous reader quotes a report from the Washington Post: Brandon Barrett arrived here two weeks ago, sick but hopeful, like dozens before him. Just a few years back, he could dead lift 660 pounds. After an injury while training to be a professional dirt-bike rider, he opened a motorcycle shop just north of Buffalo. When he wasn't working, he would cleanse his mind through rigorous meditation. In 2019, he began getting sick. And then sicker. Brain fog. Memory issues. Difficulty focusing. Depression. Anxiety. Fatigue. Brandon was pretty sure he knew why: the cell tower a quarter-mile behind his shop and all the electromagnetic radiation it produces, that cellphones produce, that WiFi routers produce, that Bluetooth produces, that the whole damn world produces. He thought about the invisible waves that zip through our airspace -- maybe they pollute our bodies, somehow? [...]

Then Brandon read about Green Bank, an unincorporated speck on the West Virginia map, hidden in the Allegheny Mountains, about a four-hour drive southwest of D.C. There are no cell towers there, by design. He read that other sick people had moved here and gotten better, that the area's electromagnetic quietude is protected by the federal government. Perhaps it could protect Brandon. It's quiet here so that scientists can listen to corners of the universe, billions of light-years away. In the 1950s, the federal government snatched up farmland to build the Green Bank Observatory. It's now home to the Robert C. Byrd Green Bank Radio Telescope, the largest steerable telescope in the world at 7,600 metric tons and a height of 485 feet. Its 2.3-acre dish can study quasars and pulsars, map asteroids and planets, and search for evidence of extraterrestrial life.

The observatory's machines are so sensitive that terrestrial radio waves would interfere with their astronomical exploration, like a shout (a bunch of WiFi signals) drowning out a whisper (signals from the clouds of hydrogen hanging out between galaxies). So in 1958, the Federal Communications Commission created the National Radio Quiet Zone, a 13,000-square-mile area encompassing wedges of both Virginia and West Virginia, where radio transmissions are restricted to varying degrees. At its center is a 10-mile zone around the observatory where WiFi, cellphones and cordless phones -- among many other types of wave-emitting equipment -- are outlawed. Wired internet is okay, as are televisions -- though you must have a cable or satellite provider. It's not a place out of 100 years ago. More like 30. If you want to make plans to meet someone, you make them in person. Some people move here to work at the observatory. Others come because they feel like they have to. These are the 'electrosensitives,' as they often refer to themselves. They are ill, and Green Bank is their Lourdes. The electrosensitives guess that they number at least 75 in Pocahontas County, which has a population of roughly 7,500. Literary Hub, the BBC, Slate, and the Washingtonian have non-paywalled articles about Green Bank and the "wi-fi refugees" that shelter there.

The first 5G Internet of Things (IoT) devices are launching soon. According to Fierce Wireless, T-Mobile plans to launch its first RedCap devices by the end of the year, while AT&T's devices are expected sometime in 2025. From the report: All of this should pave the way for higher performance 5G gadgets to make an impact in the world of IoT. RedCap, which stands for reduced capabilities, was introduced as part of the 3GPP's Release 17 5G standard, which was completed -- or frozen in 3GPP terms -- in mid-2022. The specification, which is also called NR-Light, is the first 5G-specific spec for IoT.

RedCap promises to offer data transfer speeds of between 30 Mbps to 80 Mbps. The RedCap spec greatly reduces the bandwidth needed for 5G, allowing the signal to run in a 20 MHz channel rather than the 100 MHz channel required for full scale 5G communications.

An anonymous reader quotes a report from Ars Technica: The Federal Communications Commission gave Starlink and T-Mobile emergency authority to provide satellite-to-phone coverage in areas hit by Hurricane Helene. "SpaceX and T-Mobile have been given emergency special temporary authority by the FCC to enable Starlink satellites with direct-to-cell capability to provide coverage for cell phones in the affected areas of Hurricane Helene," SpaceX said yesterday. "The satellites have already been enabled and started broadcasting emergency alerts to cell phones on all networks in North Carolina. In addition, we may test basic texting (SMS) capabilities for most cell phones on the T-Mobile network in North Carolina."

SpaceX warned of limits since the service isn't ready for a commercial rollout. "SpaceX's direct-to-cell constellation has not been fully deployed, so all services will be delivered on a best-effort basis," the company said. Starlink is being used to provide wireless emergency alerts to cell phones from all carriers in North Carolina, according to Ben Longmier, senior director of satellite engineering for SpaceX. "We are also closely monitoring Hurricane Milton and standing by ready to take action in Florida," he wrote.

The FCC said (PDF) the approval "enabl[es] SpaceX to operate Supplemental Coverage from Space (SCS) in the 1910-1915 MHz and 1990-1995 MHz frequency bands leased from T-Mobile in areas affected by the Hurricane Helene." An FCC spokesperson told Ars that the approval is for all areas affected by Hurricane Helene, although it's only active in North Carolina so far. The FCC also said (PDF) that it is granting "special temporary authorities to licensees and issuing rule waivers to help communications providers maintain and restore service, support emergency operations, and assist public safety, including search and rescue efforts." Separately, the FCC last week waived (PDF) certain Lifeline program eligibility rules to help people in disaster areas (PDF) apply for discounted phone and broadband service.

"China Telecom, one of the largest wireless carriers in mainland China, says that it has developed two large language models (LLMs) relying solely on domestically manufactured AI chips..." reports Tom's Hardware. "If the information is accurate, this is a crucial milestone in China's attempt at becoming independent of other countries for its semiconductor needs, especially as the U.S. is increasingly tightening and banning the supply of the latest, highest-end chips for Beijing in the U.S.-China chip war." Huawei, which has mostly been banned from the U.S. and other allied countries, is one of the leaders in China's local chip industry... If China Telecom's LLMs were indeed fully trained using Huawei chips alone, then this would be a massive success for Huawei and the Chinese government.
The project's GitHub page "contains a hint about how China Telecom may have trained the model," reports the Register, "in a mention of compatibility with the 'Ascend Atlas 800T A2 training server' — a Huawei product listed as supporting the Kunpeng 920 7265 or Kunpeng 920 5250 processors, respectively running 64 cores at 3.0GHz and 48 cores at 2.6GHz. Huawei builds those processors using the Arm 8.2 architecture and bills them as produced with a 7nm process."

The South China Morning Post says the unnamed model has 1 trillion parameters, according to China Telecom, while the TeleChat2t-115B model has over 100 billion parameters.

Cisco is exiting the LoRaWAN market for IoT device connectivity, with no migration plans for customers. "LoRaWAN is a low power, wide area network specification, specifically designed to connect devices such as sensors over relatively long distances," notes The Register. "It is built on LoRa, a form of wireless communication that uses spread spectrum modulation, and makes use of license-free sub-gigahertz industrial, scientific, and medical (ISM) radio bands. The tech is overseen by the LoRa Alliance." From the report: Switchzilla made this information public in a notice on its website announcing the end-of-sale and end-of-life dates for Cisco LoRaWAN. The last day customers will be able to order any affected products will be January 1, 2025, with all support ceasing by the end of the decade. The list includes Cisco's 800 MHz and 900 MHz LoRaWAN Gateways, plus associated products such as omni-directional antennas and software for the Gateways and Interface Modules. If anyone was in any doubt, the notification spells it out: "Cisco will be exiting the LoRaWAN space. There is no planned migration for Cisco LoRaWAN gateways."

Vertical Bridge has acquired the rights to lease and operate over 6,000 wireless towers from Verizon for $3.3 billion as part of a 10-year agreement, with potential extensions of up to 50 years. Capacity Media reports: "Upon the completion of this transaction, these assets, together with our existing portfolio which includes thousands of young, purpose-built towers, enhance Vertical Bridge's position as a fast, friendly, and flexible colocation partner to the wireless industry," said Ron Bizick, President and CEO of Vertical Bridge. Terms of the deal provide Verizon access to additional space on the towers for future use.

The US carrier said its latest deal with Vertical Bridge supports existing efforts to drive tower-related costs. "As the nation's largest mobility provider, we are well positioned with greater financial flexibility to invest in our business, return value to our shareholders and make the nation's best network even better for customers," said Hans Vestberg, chair and CEO of Verizon. The transaction is expected to close by the end of 2024, subject to closing conditions. Earlier this month, Verizon announced a deal to acquire Frontier Communications for $9.6 billion.

DirecTV has agreed to acquire struggling rival Dish Network, creating a satellite TV behemoth with nearly 20 million subscribers. The complex transaction, announced Monday, involves private equity firm TPG acquiring a majority stake in DirecTV from AT&T for $7.6 billion. DirecTV will then purchase Dish for $1 and assume its debt.

The deal provides a lifeline for Dish, which faces $2 billion in debt due November with only $500 million in available cash. EchoStar, Dish's parent company, will retain its wireless spectrum investments and operate independently. Subject to regulatory approval and creditor agreement, the merger is expected to close in late 2025. DirecTV and TPG will provide $2.5 billion to cover Dish's immediate financial needs. The deal's fate remains uncertain, as a similar 2002 merger attempt was blocked on antitrust grounds.

An anonymous reader shared this report from the Washington Post: Look at the top right corner of your phone. You might see an icon with "5G" and another with vertical bars showing the strength of your internet connection. Those symbols don't mean what you think they do.

If your phone shows "5G," you're not necessarily connected to the latest and zippiest cellphone network technology. It might just mean that 5G connections are available nearby. And the bars are a cellular version of a shrug. There is no standard measure of how much signal strength each bar represents. "The connection icon is a lie," said Avi Greengart, president of the technology analysis firm Techsponential...

The good news is you might not need 5G, anyway. Most of the time, your phone calls, texting and web surfing are perfectly fine on the prior generation of wireless technology called 4G or sometimes "LTE." Many phone networks will funnel you over 5G service when it makes a real difference, like if you're on a video call or playing an intense video game.

If you see more specific types of 5G icons, like "5G UW" used by Verizon or "5G UC" if you're on T-Mobile service, Hyers said you're probably connected to a 5G network at that moment. Those extra letters or symbols sometimes indicate types of 5G technology that are capable of faster and more reliable connections, but they aren't always better, depending on your circumstances. Confusingly, AT&T has showed "5G E" icons on phones. That is not 5G service at all.
Here's how major carriers responded to the Post's reporter:

• "AT&T said its '5G' indicators on phones line up with a telecommunications standards organization that established the icon to mean 5G networks are available."

• "Verizon didn't respond to my questions."

• "T-Mobile said for most of its cellphone network, your phone accurately reflects if you're on 5G."

The article suggests setting your phone to just automatically switch to 5G networks when high-bandwidth applications are in use...

Longtime Slashdot reader penciling_in shares a report from CircleID: Starlink, SpaceX's satellite-based internet service, has hit a major milestone by surpassing 4 million subscribers worldwide. SpaceX confirmed the news on Thursday after company President Gwynne Shotwell hinted earlier in the week that the service would reach the mark within days. Since its beta launch in October 2020, Starlink has rapidly scaled, growing from 1 million subscribers by December 2022, to 2 million by September 2023, and now 4 million just months later. The service operates through a vast constellation of nearly 6,000 satellites, providing satellite internet to users in almost 100 countries, including expanding into previously underserved regions like Africa and the Pacific islands. [While competition from OneWeb and Amazon's Project Kuiper looms, Starlink remains the market leader. However, challenges like slowing U.S. growth and concerns over satellite interference with radio astronomy persist.] Starlink is coming to United Airlines' entire fleet and Hawaiian Airlines Airbus flights. Air France also announced yesterday that it, too, will support free Starlink Wi-Fi on all its aircraft.

Hot on the heels of United Airlines' Starlink announcement, Hawaiian Airlines said it, too, is offering "fast and free Starlink Wi-Fi" across its entire Airbus fleet. CNET reports: Hawaiian Airlines is now the first major carrier to use Elon Musk's satellite internet service, which taps more than 7,000 satellites in low earth orbit to deliver high-speed internet worldwide. "In Starlink's low earth orbit constellation of advanced satellites, the latest of which utilize a revolutionary laser mesh network, we found an ideal solution to ensure reliable, high-speed, low-latency Wi-Fi on transpacific flights," a Hawaiian Airlines representative told CNET. "Working with Starlink has allowed us to offer a fast and consistent in-flight connectivity experience that meets our high standard for guest service."

The company first debuted Starlink on its planes in February on a flight from Honolulu to Long Beach, California. It first struck a deal with Starlink in 2022 and has now completed installation across its entire Airbus fleet, which includes 24 A330 planes and 18 A321neos. Hawaiian Airlines will also deploy the service on its two Boeing 787-9 planes, but not its Boeing 717 aircraft, which are used on shorter flights between the Hawaiian Islands.

Wireless communication pagers, carried by thousands, exploded around the same time across Lebanon on Tuesday, injuring over 2,700 people and killing eight, in what security experts suspect was a sophisticated Israeli intelligence operation. New York Times: Hundreds of pagers blew up at the same time across Lebanon on Tuesday in an apparently coordinated attack that killed eight people and injured more than 2,700, health officials said on Tuesday. [...] Hezbollah said that pagers belonging to its members had exploded and accused Israel of being behind the attack. The Israeli military declined to comment.

[...] Three officials briefed on the attack said that it had targeted hundreds of pagers belonging to Hezbollah operatives who have used such devices for years to make it harder for their messages to be intercepted. The devices were programmed to beep for several seconds before exploding, according to the officials, who spoke on the condition of anonymity because of the sensitivity of the matter.

Edward Snowden said, "If it were iPhones that were leaving the factory with explosives inside, the media would be a hell of a lot faster to cotton on to what a horrific precedent has been set today. Nothing can justify this. It's a crime. A crime. And everyone in the world is less safe for it."

An EFF article calls out a "brazen attempt to privatize" a wireless frequency band (900 MHz) which America's FCC's left " as a commons for all... for use by amateur radio operators, unlicensed consumer devices, and industrial, scientific, and medical equipment." The spectrum has also become "a hotbed for new technologies and community-driven projects. Millions of consumer devices also rely on the range, including baby monitors, cordless phones, IoT devices, garage door openers." But NextNav would rather claim these frequencies, fence them off, and lease them out to mobile service providers. This is just another land-grab by a corporate rent-seeker dressed up as innovation. EFF and hundreds of others have called on the FCC to decisively reject this proposal and protect the open spectrum as a commons that serves all.

NextNav [which sells a geolocation service] wants the FCC to reconfigure the 902-928 MHz band to grant them exclusive rights to the majority of the spectrum... This proposal would not only give NextNav their own lane, but expanded operating region, increased broadcasting power, and more leeway for radio interference emanating from their portions of the band. All of this points to more power for NextNav at everyone else's expense.

This land-grab is purportedly to implement a Positioning, Navigation and Timing (PNT) network to serve as a US-specific backup of the Global Positioning System(GPS). This plan raises red flags off the bat. Dropping the "global" from GPS makes it far less useful for any alleged national security purposes, especially as it is likely susceptible to the same jamming and spoofing attacks as GPS. NextNav itself admits there is also little commercial demand for PNT. GPS works, is free, and is widely supported by manufacturers. If Nextnav has a grand plan to implement a new and improved standard, it was left out of their FCC proposal. What NextNav did include however is its intent to resell their exclusive bandwidth access to mobile 5G networks. This isn't about national security or innovation; it's about a rent-seeker monopolizing access to a public resource. If NextNav truly believes in their GPS backup vision, they should look to parts of the spectrum already allocated for 5G.

The open sections of the 900 MHz spectrum are vital for technologies that foster experimentation and grassroots innovation. Amateur radio operators, developers of new IoT devices, and small-scale operators rely on this band. One such project is Meshtastic, a decentralized communication tool that allows users to send messages across a network without a central server. This new approach to networking offers resilient communication that can endure emergencies where current networks fail. This is the type of innovation that actually addresses crises raised by Nextnav, and it's happening in the part of the spectrum allocated for unlicensed devices while empowering communities instead of a powerful intermediary. Yet, this proposal threatens to crush such grassroots projects, leaving them without a commons in which they can grow and improve.

This isn't just about a set of frequencies. We need an ecosystem which fosters grassroots collaboration, experimentation, and knowledge building. Not only do these commons empower communities, they avoid a technology monoculture unable to adapt to new threats and changing needs as technology progresses. Invention belongs to the public, not just to those with the deepest pockets. The FCC should ensure it remains that way.

NextNav's proposal is a direct threat to innovation, public safety, and community empowerment. While FCC comments on the proposal have closed, replies remain open to the public until September 20th. The FCC must reject this corporate land-grab and uphold the integrity of the 900 MHz band as a commons.

For 30 days, 17,000 AT&T workers in nine different states from the CWA union went on strike. As it began one North Carolina newspaper noted some AT&T customers "report prolonged internet outages." Last week an Emory University economist told NPR that "If it wasn't disruptive or it didn't have any kind of negative element towards customers, then AT&T, I suspect, wouldn't feel any kind of pressure to negotiate."

The 30-day strike was "the longest telecommunications strike in the region's history," according to the union — announcing today that they'd now negotiated "strong tentative contract agreements" and that workers would report to work for their scheduled shifts tomorrow. The new contract in the Southeast covers 17,000 workers technicians, customer service representatives and others who install, maintain and support AT&T's residential and business wireline telecommunications network in Alabama, Florida, Georgia, Kentucky, Louisiana, Mississippi, North Carolina, South Carolina and Tennessee.

Wages and health care costs were key issues at the bargaining table, and the five-year agreement includes across the board wage increases of 19.33%, with additional 3% increases for Wire Technicians and Utility Operations. The health care agreement holds health care premiums steady in the first year and lowers them in the second and third years, with modest monthly increases in the final two years.
The statement adds that "CWA members and retirees from every region and sector of our union mobilized in support of our bargaining teams, including by distributing flyers with information about the strike at AT&T Wireless stores." CWA District 3 Vice President Richard Honeycutt added "We know that our customers have faced hardship during the strike as well. We are happy to be getting back to work keeping our communities safe and connected."

There's also a separate four-year agreement covering 8,500 AT&T West workers in California and Nevada. "Union members will meet to review the tentative agreements, before holding ratification votes in each region."

AT&T's chief operating officer said the Southeast agreement will "support our competitive position in the broadband industry where we can grow and win against our mostly non-union competitors."

A new survey released on Tuesday found that Americans used over 100 trillion megabytes of wireless data last year -- a 36% increase from the previous year and the largest single-year increase in the history of wireless data consumption. Reuters reports: The increase -- 26 trillion MBs over 2022 -- comes as a growing number of 5G wireless devices are being used, said wireless industry association CTIA that represents major wireless carriers like Verizon, AT&T, T-Mobile, and technology firms. The total number of wireless connections rose to 558 million last year, up 6% over 2022, the survey found.

Demand for spectrum use is soaring, driven in part by more wireless use in advancements including drones, self-driving vehicles, space missions and precision agriculture. The survey said the number of minutes Americans spent talking on the phone fell slightly from 2.5 trillion in 2022 to 2.4 trillion in 2023 and text messages were about the same at 2.1 trillion in 2023 over the prior year.

Apple says AirPods Pro 2 will receive a software feature "soon" that will turn the wireless earbuds into "clinical-grade" hearing aids. "This includes a hearing protection mode being enabled by default, offering passive noise cancellation in loud environments," adds 9to5Mac. From the report: Firstly, users can take a clinically-validated hearing test. The hearing test uses your AirPods and iPhone, and can be conducted by a user in under five times. The result of your hearing test can be viewed securely in the Health app. If hearing loss is detected, the hearing aid mode is then available to use. The AirPods will make it easier to hear sounds from the world around you. A custom hearing profile is automatically applied when listening to audio, like music or podcasts.

The hearing aid feature is currently making its way through the FDA and other regulatory bodies. Apple said the functionality will be available in more than 100 countries. The feature will be enabled through a free software update coming later this year to AirPods Pro 2.
