"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.

The Bluetooth Special Interest Group (SIG) has released version 6.0 of the Bluetooth Core Specification, introducing several new features and enhancements. The update includes Bluetooth Channel Sounding, which brings true distance awareness to devices, potentially improving "Find My" solutions and digital key security.

Other additions include decision-based advertising filtering to improve scanning efficiency, and a monitoring advertisers feature to inform devices when other Bluetooth units move in and out of range. The specification also enhances the Isochronous Adaptation Layer to reduce latency in certain use cases. Version 6.0 expands the Link Layer Extended Feature Set to support a larger number of features, reflecting Bluetooth LE's growing sophistication. Additionally, it introduces negotiable frame spacing in connections and connected isochronous streams, moving away from the fixed 150 us value in previous versions.

Verizon is in advanced talks to acquire Frontier Communications in a deal that would bolster the company's fiber network to compete with rivals including AT&T, WSJ reported Wednesday, citing people familiar with the matter. From the report: An announcement could come this week, granted the talks don't hit any last-minute snags, the people said. A deal would be sizable, given Frontier's market value of over $7 billion. The company, cobbled together by several deals over the years, provides broadband connections to about three million locations across 25 states.

Verizon, the top cellphone carrier by subscribers, has faced increased pressure from competitors and from cable-TV companies that offer discounted wireless service backed by Verizon's own cellular network. Verizon has its Fios-branded fiber network, and AT&T has focused on expanding its fiber network since shedding its WarnerMedia assets in 2022. Fiber M&A has heated up as telecom companies and financial firms pour capital into neighborhoods that lack high-speed broadband or offer only one internet provider, usually from a cable-TV company.

During a 2023 deployment, senior enlisted leaders aboard the Navy ship USS Manchester secretly installed a Starlink Wi-Fi network, allowing them exclusive internet access in violation of Navy regulations. "Unauthorized Wi-Fi systems like the one [then-Command Senior Chief Grisel Marrero] set up are a massive no-no for a deployed Navy ship, and Marrero's crime occurred as the ship was deploying to the West Pacific, where such security concerns become even more paramount among heightened tensions with the Chinese," reports Navy Times. From the report: As the ship prepared for a West Pacific deployment in April 2023, the enlisted leader onboard conspired with the ship's chiefs to install the secret, unauthorized network aboard the ship, for use exclusively by them. So while rank-and-file sailors lived without the level of internet connectivity they enjoyed ashore, the chiefs installed a Starlink satellite internet dish on the top of the ship and used a Wi-Fi network they dubbed "STINKY" to check sports scores, text home and stream movies. The enjoyment of those wireless creature comforts by enlisted leaders aboard the ship carried serious repercussions for the security of the ship and its crew. "The danger such systems pose to the crew, the ship and the Navy cannot be understated," the investigation notes.

Led by the senior enlisted leader of the ship's gold crew, then-Command Senior Chief Grisel Marrero, the effort roped in the entire chiefs mess by the time it was uncovered a few months later. Marrero was relieved in late 2023 after repeatedly misleading and lying to her ship's command about the Wi-Fi network, and she was convicted at court-martial this spring in connection to the scheme. She was sentenced to a reduction in rank to E-7 after the trial and did not respond to requests for comment for this report. The Navy has yet to release the entirety of the Manchester investigation file to Navy Times, including supplemental enclosures. Such records generally include statements or interview transcripts with the accused.

But records released so far show the probe, which wrapped in November, found that the entire chiefs mess knew about the secret system, and those who didn't buy into it were nonetheless culpable for not reporting the misconduct. Those chiefs and senior chiefs who used, paid for, helped hide or knew about the system were given administrative nonjudicial punishment at commodore's mast, according to the investigation. All told, more than 15 Manchester chiefs were in cahoots with Marrero to purchase, install and use the Starlink system aboard the ship. "This agreement was a criminal conspiracy, supported by the overt act of bringing the purchased Starlink onboard USS MANCHESTER," the investigation said. "Any new member of the CPO Mess which then paid into the services joined that conspiracy following the system's operational status."

Records obtained by Navy Times via a Freedom of Information Act request reveal a months-long effort by Marrero to obtain, install and then conceal the chiefs Wi-Fi network from superiors, including the covert installation of a Starlink satellite dish on the outside of the Manchester. When superiors became suspicious about the existence of the network and confronted her about it, Marrero failed to come clean on multiple occasions and provided falsified documents to further mislead Manchester's commanding officer, the investigation states. "The installation and usage of Starlink, without the approval of higher headquarters, poses a serious risk to mission, operational security, and information security," the investigation states.

A new study of broadband reliability finds a top-two finish that you might not expect from recent surveys of ISP customer satisfaction: Charter's Spectrum and Comcast's Xfinity, the two largest cable operators in the US. From a report: Opensignal's report, published Thursday, draws on software telemetry collected from April 1 through June 29 of downtime, consistency of service, and how well a provider meets basic thresholds for speed, latency, and other core performance metrics. Spectrum comes in first with a "Reliability Experience" score of 741 out of 1,000, followed by Xfinity with 710, Verizon with 625, AT&T with 546, and T-Mobile with 525. Opensignal chose those five companies to study because each passes more than a third of US homes.

But while Comcast and Charter employ the same basic cable architecture except for a few fiber-to-the-home pockets, Verizon and AT&T have mixed networks. That includes extensive and growing fiber service but also fixed 4G and 5G wireless from Verizon and hybrid-fiber broadband from AT&T, both of which lack fiber's speed and capacity advantages, plus obsolete DSL connectivity. T-Mobile's home connectivity, meanwhile, is almost exclusively fixed wireless.

After a couple of years of regular use, Samsung's $400 Galaxy Ring will end up contributing to the growing e-waste problem. "The Galaxy Ring -- and all smart rings like it -- comes with a huge string attached," writes iFixit in a blog post. "It's 100% disposable, just like the AirPod-style Buds3 that Samsung just released. The culprit? The lithium ion batteries." ZDNet reports: The problem is the battery, and how they have a finite lifespan. Usually that's about 400 recharge cycles, and after that the batteries are finished. And if you can't replace it, then it's the end of the line for the gadget, and it's tossed onto the e-waste pile. [...]

iFixit is damning about this sort of tech. "There's nothing wrong with simple but there is something wrong with unrepairable. Just like the Galaxy Buds3, the Galaxy Ring is a disposable tech accessory that isn't designed to last more than two years." And the bottom line is simple: "We can't recommend buying disposable tech like this." Here's what iFixit's Shahram Mokhtari had to say about the Galaxy Ring's battery, after putting it through a CT scanner: On the right hand side of the ring is the faint outline of a lithium polymer battery pouch. There's an inductive coil sitting right on top of the battery (the lines that look like a rectangular track) and another very similar inductive coil that's parallel and slightly separated from the first. That second inductive coil is inside the charging case and works together with the inductive coil in the ring to recharge the battery inside the Galaxy Ring. Inductive charging is the only practical way to deliver power to a device that doesn't have any ports. But there's something else here that sticks out like a sore thumb ... that is a press connector joining the battery to the rest of the board! This is a surprising use of space, why isn't this directly soldered? Nobody is getting back in there to disconnect this thing!

We love press connectors, they're easy to work with and make replacing batteries a sight easier than desoldering a half dozen wires. But this one is sealed into the device and serves no purpose in replacement or repair. Our best guess as to why it's in the Galaxy Ring: The battery and wireless charging coil were made in one place, the circuit board somewhere else, and it all comes to a production line somewhere where the two need to be connected together quickly and cheaply. Hence the press connector. It's not for your benefit, it's for the manufacturers.

Atari has just announced a renewed version of its 7800 home console from 1986. Polygon: Dubbed the 7800 Plus, the new console will launch later this winter but is already available to pre-order from Atari for $129.99. The 7800 Plus is a scaled-down version of the original hardware equipped with an HDMI connection and has the ability to play first and third-party cartridges for the Atari 2600 and 7800. Additionally, you'll have the option to play your games in their original 4:3 aspect ration, or upscale them to widescreen format. While emulators and other options for playing retro Atari games exist, playing the games on their original hardware remains the definitive way to experience many of these classic titles.

Along with its new console, Atari also announced a pair of new wireless controllers. The CX40 Plus wireless Joystick and CX78 Plus Wireless gamepad are loving recreations of the original hardware as they shipped with the Atari 2600 and 7800. Both of the new controllers are compatible with either the Atari 2600 Plus (released last year) or the new 7800 Plus consoles but can also be hooked up to your PC by using the included USB-C adapter -- they're even compatible with an original 2600 or 7800 if you have one lying around. Both peripherals are available from Atari now and cost $34.99.

Bloomberg's Mark Gruman remembers how Apple's hardware group "allowed Apple to dump Intel chips from its entire Mac lineup."

And they're now building an in-house cellular modem: For more than a decade, Apple has used modem chips designed by Qualcomm... But in 2018 — while facing a legal battle over royalties and patents — Apple started work on its own modem design.... It's devoting billions of dollars, thousands of engineers and millions of working hours to a project that won't really improve its devices — at least at the outset...

Over the past few years, Apple's modem project has suffered numerous setbacks. There have been problems with performance and overheating, and Apple has been forced to push back the modem's debut until next year at the earliest. The rollout will take place on a gradual basis — starting with niche models — and take a few years to complete. In a sign of this slow transition, Apple extended its supplier agreement with Qualcomm through March 2027... But Qualcomm has said that Apple will still have to pay it some royalties regardless (the chipmaker believes that Apple won't be able to avoid infringing its patents).

So it's hard to tell how big the benefits will be in the near term. Down the road, there are plans for Apple to fold its modem design into a new wireless chip that handles Wi-Fi and Bluetooth access. That would create a single connectivity component, potentially improving reliability and battery life. There's also the possibility that Apple could one day combine all of this into the device's main system on a chip, or SoC. That could further cut costs and save space inside the iPhone, allowing for more design choices. Furthermore, if Apple does ultimately save money by switching away from Qualcomm, it could redirect that spending toward new features and components.

An anonymous reader quotes a report from NPR: Safety advocates have been touting the potential of technology that allows vehicles to communicate wirelessly for years. So far, the rollout has been slow and uneven. Now the U.S. Department of Transportation is releasing a roadmap it hopes will speed up deployment of that technology -- and save thousands of lives in the process. "This is proven technology that works," Shailen Bhatt, head of the Federal Highway Administration, said at an event Friday to mark the release of the deployment plan (PDF) for vehicle-to-everything, or V2X, technology across U.S. roads and highways. V2X allows cars and trucks to exchange location information with each other, and potentially cyclists and pedestrians, as well as with the roadway infrastructure itself. Users could send and receive frequent messages to and from each other, continuously sharing information about speed, position, and road conditions -- even in situations with poor visibility, including around corners or in dense fog or heavy rain. [...]

Despite enthusiasm from safety advocates and federal regulators, the technology has faced a bumpy rollout. During the Obama administration, the National Highway Traffic Safety Administration proposed making the technology mandatory on cars and light trucks. But the agency later dropped that idea during the Trump administration. The deployment of V2X has been "hampered by regulatory uncertainty," said John Bozzella, president and CEO of the Alliance for Automotive Innovation, a trade group that represents automakers. But he's optimistic that the new plan will help. "This is the reset button," Bozzella said at Friday's announcement. "This deployment plan is a big deal. It is a crucial piece of this V2X puzzle." The plan lays out some goals and targets for the new technology. In the short-term, the plan aims to have V2X infrastructure in place on 20% of the National Highway System by 2028, and for 25% of the nation's largest metro areas to have V2X enabled at signalized intersections. V2X technology still faces some daunting questions, including how to pay for the rollout of critical infrastructure and how to protect connected vehicles from cyberattack. But safety advocates say it's past time to find the answers.
