Pakistan's Internet Connectivity Abruptly Plummets To 20% (pakistantoday.com.pk) 14

Pakistan's internet connectivity dropped to 20% of normal levels Tuesday, affecting the country's 116 million internet users, according to NetBlocks. The outage primarily impacted backbone operator PTCL. It's unclear what caused the outage. The Wireless and Internet Service Providers Association of Pakistan noted the date coincided with a similar collapse in 2022. Pakistan suffered $1.62 billion in economic losses from internet disruptions in 2024, the highest globally. The country confirmed installing a national internet firewall months earlier.

AOL Finally Discontinues Its Dial-Up Internet Access - After 34 Years (pcmag.com) 75

AOL (now a Yahoo subsidiary) just announced its dial-up internet service will be discontinued at the end of September.

"The change also means the retirement of the AOL Dialer software and the AOL Shield browser, both designed for older operating systems and slow connections that relied on the familiar screech of a modem handshake," remembers Slashdot reader BrianFagioli (noting that dial-up Internet "was once the gateway to the web for millions of households, back when speeds were measured in kilobits and waiting for a picture to load could feel like an eternity.")

AOL's dial-up service "has been publicly available for 34 years," writes Tom's Hardware. But AppleInsider notes the move comes more than 40 years after AOL started "as a very early Apple service." AOL itself started back in 1983 under the name Control Video Corporation, offering online services for the Atari 2600 console. After failing, it became Quantum Computer Services in 1985, eventually launching AppleLink in 1988 to connect Macintosh computers together... With the launch of PC Link for IBM-compatible PCs in 1988 and parting from Apple in October 1989, the company rebranded itself as America Online, or AOL... Even at its height, dial-up connections could get up to 56 kilobits per second under ideal conditions, while modern connections are measured in megabits and gigabits. Most of the service was also what's considered a "walled garden," with features that were only available through AOL itself and that it wasn't the actual, untamed Internet.
In the 1990s AOL "was how millions of people were introduced to the Internet," the article remembers, adding that "Even after the AOL Time Warner acquisition and the 2015 acquisition by Verizon, AOL was still a popular service. Astoundingly, it counted about two million dial-up subscribers at the time." In the 2021 acquisition of assets from Verizon by Apollo Global Management, AOL was said to have 1.5 million people paying for services. However, this was more for technical support and software, rather than for actual Internet access. A CNBC report at the time reports that the dial-up user count was "in the low thousands".... While it dies off, not with a bang but a whimper, AOL's dial-up is still remembered as one of the most transformative services in the Internet age.
"This change does not impact the numerous other valued products and services that these subscribers are able to access and enjoy as part of their plans," a Yahoo spokesperson told PC Magazine this week. "There is also no impact to our users' free AOL email accounts." AOL's disastrous 2001 merger with Time Warner and ongoing inability to deliver broadband to its customers... left it on a path to decline that acquiring such widely read sites as Engadget [2005] and TechCrunch [2010] did not stem. By 2014, the number of dial-up AOL customers had collapsed to 2.34 million. A year later, Verizon bought the company for $4.4 billion in an internet-content play that turned out to be as doomed as the Time Warner transaction. In 2021, Verizon unloaded both AOL and Yahoo, which it had separately purchased in 2017, to the private-equity firm Apollo Global Management....

The demise of AOL's dial-up service does not mean the extinction of the oldest form of consumer online access. Estimates from the Census Bureau's 2023 American Community Survey show 163,401 Americans connected to the internet via dial-up that year.

That was by far the smallest segment of the internet-using population, dwarfed by 100,166,949 subscribing to such forms of broadband as "cable, fiber optic, or DSL"; 8,628,648 using satellite; 3,318,901 using "Internet access without a subscription" (which suggests Wi-Fi from coffee shops or public libraries); and 1,445,135 via "other service."

The remaining AOL dial-up subscribers will need to find some sort of replacement, which in rural areas may be limited to fixed wireless or SpaceX's considerably more expensive Starlink. Or they may wind up joining the ranks of Americans with no internet access: 6,866,059, in those 2023 estimates.

The FCC Will Review Emergency Alert Systems in the US (engadget.com) 29

An anonymous reader shares a report: The Federal Communications Commission is planning a review of the US emergency alert systems. Both the Emergency Alert System (EAS) and the Wireless Emergency Alerts (WAS) will be subject to a "re-examination" by the agency. "We want to ensure that these programs deliver the results that Americans want and need," FCC Chairman Brendan Carr posted on X.

The announcement of this plan notes that the infrastructure underlying the EAS -- which includes radio, television, satellite and cable systems -- is 31 years old, while the framework underpinning the WAS mobile device alerts is 13 years old. The FCC review will also assess what entities should be able to send alerts on those systems, as well as topics such as geographic targeting and security.

Vortex's Wireless Take On the Model M Keyboard: Cover Band Or New Legend? (ofb.biz) 74

IBM's legendary Model M keyboard was sturdy and solid. But "What would happen if you took the classic layout and look of the Model M and rebuilt it with modern mechanical guts?" asks long-time Slashdot reader uninet. Writing for the long-running tech blog Open for Business , they review a new wireless keyboard from Vortex that was clearly inspired by the Model M: The result is a unique keyboard with one foot in two different decades... Let's call it the Vortex M for simplicity's sake.

I first became aware of it on a Facebook ad and was immediately fascinated. It looked so close to the original Model M, I wondered if someone else had gotten access to an original mold and was trying Unicomp's game. No, they've just managed to copy the aesthetic to a nearly uncanny level... The Vortex M eschews the normal eye candy we expect on modern keyboards and attempts the closest duplication of IBM's staid early PC design sensibility I can imagine. Off-white, rugged and absolutely no frills of lighting. If you're looking for cutesy, forget it.

The keyboard's casing has the same highly textured plastic that looks and feels instantly familiar to anyone who spent too many hours interacting with early PCs. Model M to a tee. The keycaps likewise look the part... The Vortex M looks like a Model M. Its build quality feels like a Model M. But one key press and it becomes clear this is a different beast. Underneath the Model M-styled skin, Vortex's keyboard is a very modern design — everything the Unicomp is not. For our test, Vortex provided a keyboard with Cherry MX Blues, the classic clicky option the company and I both thought would best match up against Model M's buckling springs...

Vortex's product configurator offers a variety of common and less common Cherry and Gateron options, if you want to get a different sort of feel in lieu of the clicky I tested. This is possible with an MX switch-style keyboard and impossible with buckling springs with their one option of bold clicky. Not only can this be done when ordering, but also later on, thanks to hot swap switches that allow changes without soldering. Following the modern premium board theme, Vortex paired high end switches with a gasket mount and foam padding. The combination provides a solid feeling, sound dampened typing experience. Ironically, though, for a keyboard that apes the design of perhaps the loudest keyboard on the market today, the Vortex M is (relatively) quiet even with the clicky Blues on tap...

The review's highlights:
  • "The keyboard is exquisitely crafted to look like the IBM original... "
  • "The Vortex M supports connecting to three different devices via Bluetooth, along with a 2.4 GHz receiver and a USB Type-C wired connection. "
  • There's a full complement of media hot keys — "including an emoji key ala recent Macs. "
  • "For repetitive tasks, the keyboard is programmable with macros... And unlike Unicomp's boards, Vortex's can switch between PC and Mac layouts with the press of a hotkey."
  • The keyboard uses AA batteries rather than having a built-in rechargeable battery

The keyboard ultimately gave the reviewer some cognitive dissonance. "How am I typing on a Model M and not making a racket...?"

"Pricing varies based on options, but as tested, it clocked in at $154. That's the low end of the 'premium' market and this is an exceptional board for that price."

Jack Dorsey's Bluetooth Messaging App Bitchat Now On App Store 30

Jack Dorsey's new app Bitchat is now available on the iOS App Store. The decentralized, peer-to-peer messaging app uses Bluetooth mesh networks for encrypted, ephemeral chats without requiring accounts, servers, or internet access. Dorsey said he built it over a weekend and cautioned that it "has not received external security review and may contain vulnerabilities..." TechCrunch reports: The app's UX is very minimal. There is no log-in system, and you're immediately brought to an instant messaging box, where you can see what nearby users are saying (if anyone is actually around you and using the app) and set your display name, which can be changed at any time. [...] Dorsey has not directly addressed the fake Bitchat apps on the Google Play store, but he did repost another user's X post that said that Bitchat is not yet on Google Play, and to "beware of fakes."

Bankrupt Futurehome Suddenly Makes Its Smart Home Hub a Subscription Service (arstechnica.com) 81

After filing for bankruptcy, Norwegian smart home company Futurehome abruptly transitioned its Smarthub II and other devices to a subscription-only model, disabling essential features unless users pay an annual fee. Needless to say, customers aren't too happy with the move as they bought the hardware expecting lifetime functionality and now find their smart homes significantly less smart. Ars Technica reports: Launched in 2016, Futurehome's Smarthub is marketed as a central hub for controlling Internet-connected devices in smart homes. For years, the Norwegian company sold its products, which also include smart thermostats, smart lighting, and smart fire and carbon monoxide alarms, for a one-time fee that included access to its companion app and cloud platform for control and automation. As of June 26, though, those core features require a 1,188 NOK (about $116.56) annual subscription fee, turning the smart home devices into dumb ones if users don't pay up.

"You lose access to controlling devices, configuring; automations, modes, shortcuts, and energy services," a company FAQ page says. You also can't get support from Futurehome without a subscription. "Most" paid features are inaccessible without a subscription, too, the FAQ from Futurehome, which claims to be in 38,000 households, says. After June 26, customers had four weeks to continue using their devices as normal without a subscription. That grace period recently ended, and users now need a subscription for their smart devices to work properly.

Some users are understandably disheartened about suddenly having to pay a monthly fee to use devices they already purchased. More advanced users have also expressed frustration with Futurehome potentially killing its devices' ability to work by connecting to a local device instead of the cloud. In its FAQ, Futurehome says it "cannot guarantee that there will not be changes in the future" around local API access.
Futurehome claims that introducing the subscription fee was a necessary move due to its recent bankruptcy. Its FAQ page reads: "Futurehome AS was declared bankrupt on 20 May 2025. The platform and related services were purchased from the bankruptcy estate -- 50 percent by former Futurehome owners and 50 percent by Sikom Connect -- and are now operated by FHSD Connect AS. To secure stable operation, fund product development, and provide high-quality support, we are introducing a new subscription model."

The company says the subscription fee would allow it to provide customers "better functionality, more security, and higher value in the solution you have already invested in."

Echelon Kills Smart Home Gym Equipment Offline Capabilities With Update (arstechnica.com) 52

A recent Echelon firmware update has effectively bricked offline functionality for its smart gym equipment, cutting off compatibility with popular third-party apps like QZ and forcing users to connect to Echelon's servers -- even just to view workout stats. Ars Technica reports: As explained in a Tuesday blog post by Roberto Viola, who develops the "QZ (qdomyos-zwift)" app that connects Echelon machines to third-party fitness platforms, like Peloton, Strava, and Apple HealthKit, the firmware update forces Echelon machines to connect to Echelon's servers in order to work properly. A user online reported that as a result of updating his machine, it is no longer syncing with apps like QZ, and he is unable to view his machine's exercise metrics in the Echelon app without an Internet connection. Affected Echelon machines reportedly only have full functionality, including the ability to share real-time metrics, if a user has the Echelon app active and if the machine is able to reach Echelon's servers.

Viola wrote: "On startup, the device must log in to Echelon's servers. The server sends back a temporary, rotating unlock key. Without this handshake, the device is completely bricked -- no manual workout, no Bluetooth pairing, no nothing." Because updated Echelon machines now require a connection to Echelon servers for some basic functionality, users are unable to use their equipment and understand, for example, how fast they're going without an Internet connection. If Echelon were to ever go out of business, the gym equipment would, essentially, get bricked. Viola told Ars Technica that he first started hearing about problems with QZ, which launched in 2020, at the end of 2024 from treadmill owners. He said a firmware update appears to have rolled out this month on Echelon bikes that bricks QZ functionality. In his blog, Viola urged Echelon to let its machines send encrypted data to another device, like a phone or a tablet, without the Internet. He wrote: "Users bought the bike; they should be allowed to use it with or without Echelon's services."

Humans Can Be Tracked With Unique 'Fingerprint' Based On How Their Bodies Block Wi-Fi Signals (theregister.com) 38

Researchers from La Sapienza University in Rome have developed "WhoFi," a system that uses the way a person's body distorts Wi-Fi signals to re-identify them across different locations -- even if they're not carrying a phone. By training a deep neural network on these subtle signal distortions, the researchers claim WhoFi is able to achieve up to 95.5% accuracy. The Register reports: "The core insight is that as a Wi-Fi signal propagates through an environment, its waveform is altered by the presence and physical characteristics of objects and people along its path," the authors state in their paper. "These alterations, captured in the form of Channel State Information (CSI), contain rich biometric information." CSI in the context of Wi-Fi devices refers to information about the amplitude and phase of electromagnetic transmissions. These measurements, the researchers say, interact with the human body in a way that results in person-specific distortions. When processed by a deep neural network, the result is a unique data signature.

Researchers proposed a similar technique, dubbed EyeFi, in 2020, and asserted it was accurate about 75 percent of the time. The Rome-based researchers who proposed WhoFi claim their technique makes accurate matches on the public NTU-Fi dataset up to 95.5 percent of the time when the deep neural network uses the transformer encoding architecture. "The encouraging results achieved confirm the viability of Wi-Fi signals as a robust and privacy-preserving biometric modality, and position this study as a meaningful step forward in the development of signal-based Re-ID systems," the authors say.

T-Mobile is Bringing Low-Latency Tech To 5G For the First Time (theverge.com) 16

T-Mobile is expanding support for the L4S standard across its 5G Advanced network over the next few weeks, becoming the first wireless carrier in the United States to implement the Low Latency, Low Loss, Scalable Throughput technology. The standard helps high-priority internet packets move with fewer delays to make video calls and cloud games feel smoother by allowing devices to manage congestion and reduce buffering issues that can occur even on higher bandwidth connections.

L4S is already deployed in many cities, the company said. Users will not need special phones or plans to access the network-driven improvements.

SES Completes $3 Billion Acquisition of Intelsat, Expanding Global Satellite Fleet (ses.com) 4

"The Luxembourg-based satellite company SES has now completed its acquisition of the European-based satellite company Intelsat, giving the combined company 120 active satellites in a variety of low and high Earth orbits," writes longtime Slashdot reader schwit1. "Both companies are long established, with Intelsat initially founded in the mid-1960s as a consortium of 23 nations aimed at launching the first geosynchronous communications satellites over the Atlantic and Pacific serving most of the Old World and linked to the New. The merger is an attempt by both companies to compete with the new low-orbit constellations of SpaceX, Amazon, and from China." From a press release: With a world-class network including approximately 90 geostationary (GEO), nearly 30 medium earth orbit (MEO) satellites, strategic access to low earth orbit (LEO) satellites, and an extensive ground network, SES can now deliver connectivity solutions utilizing complementary spectrum bands including C-, Ku-, Ka-, Military Ka-, X-band, and Ultra High Frequency. The expanded capabilities of the combined company will enable it to deliver premium-quality services and tailored solutions to its customers. The company's assets and networks, once fully integrated, will put SES in a strong competitive position to better serve the evolving needs of its customers including governments, aviation, maritime, and media across the globe. "Our focus is clear: to grow, to lead in high-potential markets, and to shape the future of our industry," said SES CEO Adel Al-Saleh in a statement. "This is a long-term play, and we are building with the future in mind -- growing year after year, expanding our capabilities, and creating lasting value for our customers and shareholders alike."

Fierce Network notes that the FCC is preparing to auction upper C-band spectrum (3.98-4.2 GHz), previously cleared in part by SES and Intelsat and now eyed for 5G expansion by Verizon and AT&T. With new legislative backing and industry pressure, including from CTIA and FCC Chairman Brendan Carr, the agency is being urged to act quickly to auction and open this spectrum for full-power wireless use.

Why America Still Can't Get Disaster Alerts Right (wsj.com) 199

US's emergency-warning infrastructure failed to prevent more than 100 deaths during flash flooding in Kerr County, Texas over the July 4 weekend, despite repeated warnings from the National Weather Service. At least 27 young campers and counselors died at Camp Mystic when the Guadalupe River surged during early morning hours. The alerts never reached residents who lacked cellphone service, had silenced notifications, or didn't carry phones with them.

Similar communication failures occurred during recent Los Angeles wildfires and Maui blazes. Maui's outdoor sirens never sounded during 2023 wildfires when cellular networks failed. Nearly 30% of Texas residents opt out of wireless emergency alerts, the highest rate nationally. Rural officials often lack funding or permission to send alerts through broadcasters and cellphones. So what's going on?

Federal, state and local authorities share responsibility for alerting citizens through multiple platforms, but the country's patchwork of digital and physical emergency-alert tools often lags behind rapidly developing weather events, WSJ argues.

The Atlantic has a story that adds more color: It details how officials lack training in writing effective alerts, how messages like "move to higher ground" are meaningless without context, and how the absence of warning-coordination meteorologists creates communication gaps between weather services and local authorities.

Jack Dorsey Says His 'Secure' New Bitchat App Has Not Been Tested For Security (techcrunch.com) 37

An anonymous reader quotes a report from TechCrunch: On Sunday, Block CEO and Twitter co-founder Jack Dorsey launched an open source chat app called Bitchat, promising to deliver "secure" and "private" messaging without a centralized infrastructure. The app relies on Bluetooth and end-to-end encryption, unlike traditional messaging apps that rely on the internet. By being decentralized, Bitchat has potential for being a secure app in high-risk environments where the internet is monitored or inaccessible. According to Dorsey's white paper detailing the app's protocols and privacy mechanisms, Bitchat's system design "prioritizes" security.

But the claims that the app is secure, however, are already facing scrutiny by security researchers, given that the app and its code have not been reviewed or tested for security issues at all -- by Dorsey's own admission. Since launching, Dorsey has added a warning to Bitchat's GitHub page: "This software has not received external security review and may contain vulnerabilities and does not necessarily meet its stated security goals. Do not use it for production use, and do not rely on its security whatsoever until it has been reviewed." This warning now also appears on Bitchat's main GitHub project page but was not there at the time the app debuted.

As of Wednesday, Dorsey added: "Work in progress," next to the warning on GitHub. This latest disclaimer came after security researcher Alex Radocea found that it's possible to impersonate someone else and trick a person's contacts into thinking they are talking to the legitimate contact, as the researcher explained in a blog post. Radocea wrote that Bitchat has a "broken identity authentication/verification" system that allows an attacker to intercept someone's "identity key" and "peer id pair" -- essentially a digital handshake that is supposed to establish a trusted connection between two people using the app. Bitchat calls these "Favorite" contacts and marks them with a star icon. The goal of this feature is to allow two Bitchat users to interact, knowing that they are talking to the same person they talked to before.

Hugging Face Launches $299 Robot That Could Disrupt Entire Robotics Industry (venturebeat.com) 69

An anonymous reader quotes a report from VentureBeat: Hugging Face, the $4.5 billion artificial intelligence platform that has become the GitHub of machine learning, announced Tuesday the launch of Reachy Mini, a $299 desktop robot designed to bring AI-powered robotics to millions of developers worldwide. The 11-inch humanoid companion represents the company's boldest move yet to democratize robotics development and challenge the industry's traditional closed-source, high-cost model.

The announcement comes as Hugging Face crosses a significant milestone of 10 million AI builders using its platform, with CEO Clement Delangue revealing in an exclusive interview that "more and more of them are building in relation to robotics." The compact robot, which can sit on any desk next to a laptop, addresses what Delangue calls a fundamental barrier in robotics development: accessibility. "One of the challenges with robotics is that you know you can't just build on your laptop. You need to have some sort of robotics partner to help in your building, and most people won't be able to buy $70,000 robots," Delangue explained, referring to traditional industrial robotics systems and even newer humanoid robots like Tesla's Optimus, which is expected to cost $20,000-$30,000.

Reachy Mini emerges from Hugging Face's April acquisition of French robotics startup Pollen Robotics, marking the company's most significant hardware expansion since its founding. The robot represents the first consumer product to integrate natively with the Hugging Face Hub, allowing developers to access thousands of pre-built AI models and share robotics applications through the platform's "Spaces" feature. [...] Reachy Mini packs sophisticated capabilities into its compact form factor. The robot features six degrees of freedom in its moving head, full body rotation, animated antennas, a wide-angle camera, multiple microphones, and a 5-watt speaker. The wireless version includes a Raspberry Pi 5 computer and battery, making it fully autonomous. The robot ships as a DIY kit and can be programmed in Python, with JavaScript and Scratch support planned. Pre-installed demonstration applications include face and hand tracking, smart companion features, and dancing moves. Developers can create and share new applications through Hugging Face's Spaces platform, potentially creating what Delangue envisions as "thousands, tens of thousands, millions of apps."
Reachy Mini's $299 price point could significantly transform robotics education and research. "Universities, coding bootcamps, and individual learners could use the platform to explore robotics concepts without requiring expensive laboratory equipment," reports VentureBeat. "The open-source nature enables educational institutions to modify hardware and software to suit specific curricula. Students could progress from basic programming exercises to sophisticated AI applications using the same platform, potentially accelerating robotics education and workforce development."

"... For the first time, a major AI platform is betting that the future of robotics belongs not in corporate research labs, but in the hands of millions of individual developers armed with affordable, open-source tools."

IKEA Ditches Zigbee For Thread Going All In On Matter Smart Homes (theverge.com) 44

IKEA is relaunching its smart home line with over 20 new Matter-over-Thread devices that will work across ecosystems such as Apple Home and Amazon Alexa, with or without IKEA's own hub. This marks a major shift toward openness, affordability, and interoperability, and positions IKEA as one of the first major retailers to bring Matter to the mainstream while maintaining backward compatibility with Zigbee products. The Verge reports: We don't have a lot of details on the over 20 new devices coming next year, but [David Granath of IKEA of Sweden] confirmed that they are replacing existing functions. So, new smart bulbs, plugs, sensors, remotes, buttons, and air-quality devices, including temperature and humidity monitors. They will also come with a new design. Although "not necessarily what's been leaked," says Granath, referring to images of the Bilresa Dual Button that appeared earlier this year. He did confirm that some new product categories will arrive in January, with more to follow in April and beyond, including potentially Matter-over-Wi-Fi products. Pricing will be comparable to or lower than that of previous products, which start under $10. "Affordability remains a key priority for us."
"The premium to make a product smart is not that high anymore, so you can expect new product types and form factors coming," he says. "Matter unlocks interoperability, ease of use, and affordability for us. The standardization process means more companies are sharing the workload of developing for this." Despite the move away from Zigbee, IKEA is keeping Zigbee's Touchlink functionality. This point-to-point protocol allows devices to be paired directly to each other and work together out of the box, without an app or hub -- such as the bulb and remote bundles IKEA sells. This means older Zigbee remotes can control the newer Thread bulbs and vice versa, retaining backward compatibility with its Tradfri line. "Touchlink and Matter will coexist in new products," says Granath. "It's still very important for IKEA -- not everyone wants an app or hub."

Interestingly, IKEA's new Matter-over-Thread products will also work without the IKEA hub or app, as they can be set up directly in any compatible Matter smart home ecosystem, such as Apple Home, Amazon Alexa, Google Home, Samsung SmartThings, Home Assistant, and others.

Jack Dorsey Launches a WhatsApp Messaging Rival Built On Bluetooth (cnbc.com) 66

Jack Dorsey has launched Bitchat, a decentralized, peer-to-peer messaging app that uses Bluetooth mesh networks for encrypted, ephemeral chats without requiring accounts, servers, or internet access. The beta version is live on TestFlight, with a full white paper available on GitHub. CNBC reports: In a post on X Sunday, Dorsey called it a personal experiment in "bluetooth mesh networks, relays and store and forward models, message encryption models, and a few other things."

Bitchat enables ephemeral, encrypted communication between nearby devices. As users move through physical space, their phones form local Bluetooth clusters and pass messages from device to device, allowing them to reach peers beyond standard range -- even without Wi-Fi or cell service. Certain "bridge" devices connect overlapping clusters, expanding the mesh across greater distances. Messages are stored only on device, disappear by default and never touch centralized infrastructure -- echoing Dorsey's long-running push for privacy-preserving, censorship-resistant communication.

Like the Bluetooth-based apps used during Hong Kong's 2019 protests, Bitchat is designed to keep working even when the internet is blocked, offering a censorship-resistant way to stay connected during outages, shutdowns or surveillance. The app also supports optional group chats, or "rooms," which can be named with hashtags and protected by passwords. It includes store and forward functionality to deliver messages to users who are temporarily offline. A future update will add WiFi Direct to increase speed and range, pushing Dorsey's vision for off-grid, user-owned communication even further.

Senate GOP Budget Bill Has Little-Noticed Provision That Could Hurt Your Wi-Fi (arstechnica.com) 62

An anonymous reader shares a report: Sen. Ted Cruz (R-Texas) has a plan for spectrum auctions that could take frequencies away from Wi-Fi and reallocate them for the exclusive use of wireless carriers. The plan would benefit AT&T, which is based in Cruz's home state, along with Verizon and T-Mobile.

Cruz's proposal revives a years-old controversy over whether the entire 6 GHz band should be devoted to Wi-Fi, which can use the large spectrum band for faster speeds than networks that rely solely on the 2.4 and 5 GHz bands. Congress is on the verge of passing legislation that would require spectrum to be auctioned off for full-power, commercially licensed use, and the question is where that spectrum will come from.

When the House of Representatives passed its so-called "One Big Beautiful Bill," it excluded all of the frequencies between 5.925 and 7.125 gigahertz from the planned spectrum auctions. But Cruz's version of the budget reconciliation bill, which is moving quickly toward a final vote, removed the 6 GHz band's protection from spectrum auctions. The Cruz bill is also controversial because it would penalize states that regulate artificial intelligence.

Instead of excluding the 6 GHz band from auctions, Cruz's bill would instead exclude the 7.4-8.4 GHz band used by the military. Under conditions set by the bill, it could be hard for the Commerce Department and Federal Communications Commission to fulfill the Congressional mandate without taking some spectrum away from Wi-Fi.

Comcast's New Plans Dump the Data Caps (pcmag.com) 80

Comcast is introducing new simplified, contract-free broadband plans that eliminate its unpopular 1.2TB data cap for residential customers. "The company began enforcing a data cap in 2008, when it set that limit at 250GB," notes PCMag. "Four years later, it raised that to 300GB, then lifted it to 1TB in 2016 and inched it up again to 1.25TB in 2020 after suspending it entirely during the early months of the pandemic." The report notes that existing customers will need to switch to these updated plans to benefit from the cap removal. PCMag reports: Steve Croney, Comcast's COO for connectivity and platforms, describes these new "everyday price plans" as "built on simplicity and transparency -- no hidden fees, no confusion." Comcast began showing the new plans on its sign-up pages Thursday morning. The monthly rates largely match those announced when Comcast advertised a rate-lock offer in April:

- 300Mbps downloads for $40 with a one-year lock or $55 with a five-year lock, then $70 a month
- 500Mbps for $55 with a one-year lock or $70 with a five-year lock, then $85
- 1Gbps for $70 with a one-year lock or $85 a month with a five-year lock, then $100
- 2Gbps for $100 with a one-year lock or $115 with a five-year lock, then $130

Upload speeds on those plans will vary by location but should start at 40Mbps. These plans also include one year of Xfinity Mobile wireless service, which combines Verizon's coverage with Comcast's Wi-Fi network.

Canadian Telecom Hacked By Suspected China State Group (arstechnica.com) 10

Hackers suspected of working on behalf of the Chinese government exploited a maximum-severity vulnerability, which had received a patch 16 months earlier, to compromise a telecommunications provider in Canada, officials from that country and the US said Monday. ArsTechnica: "The Cyber Centre is aware of malicious cyber activities currently targeting Canadian telecommunications companies," officials for the center, the Canadian government's primary cyber security agency, said in a statement. "The responsible actors are almost certainly PRC state-sponsored actors, specifically Salt Typhoon." The FBI issued its own nearly identical statement.

Salt Typhoon is the name researchers and government officials use to track one of several discreet groups known to hack nations all over the world on behalf of the People's Republic of China. In October 2023, researchers disclosed that hackers had backdoored more than 10,000 Cisco devices by exploiting CVE-2023-20198, a vulnerability with a maximum severity rating of 10. Any switch, router, or wireless LAN controller running Cisco's iOS XE that had the HTTP or HTTPS server feature enabled and exposed to the Internet was vulnerable. Cisco released a security patch about a week after security firm VulnCheck published its report.

NFC Release 15 Extends Tap-to-Pay Range From 0.5cm To 2cm (nfc-forum.org) 29

The NFC Forum has released NFC Release 15 (that's what it's calling it), extending the operating range of Near Field Communication connections from 0.5 centimeters to 2 centimeters -- a fourfold increase that reduces the precision required for device alignment.

The global standards body, whose board includes representatives from Apple, Google, Huawei, Infineon, NXP, Sony, and ST Microelectronics, designed the enhancement to accelerate transaction speeds and improve reliability across NFC-enabled devices. The expanded range addresses technical challenges in smaller form-factor devices like wearables and smartphones while maintaining compatibility with existing ISO/IEC 14443 standards.

The standard also incorporates support for NFC Digital Product Passport specifications, allowing single NFC tags embedded in products to store and transmit sustainability data throughout their lifecycle.
