"Deep in a pine forest in Wilcox County, Alabama, three workers dangled from the top of a 350-foot cellular tower," reports the New York Times. "They were there to rip out and replace Chinese equipment from the local wireless network..." As the United States and China battle for geopolitical and technological primacy, the fallout has reached rural Alabama and small wireless carriers in dozens of states. They are on the receiving end of the Biden administration's sweeping policies to suppress China's rise, which include trade restrictions, a $52 billion package to bolster domestic semiconductor manufacturing against China and the divestiture of the video app TikTok from its Chinese owner. What the wireless carriers must do, under a program known as "rip and replace," has become the starkest physical manifestation of the tech Cold War between the two superpowers. The program, which took effect in 2020, mandates that American companies tear out telecom equipment made by the Chinese companies Huawei and ZTE. U.S. officials have warned that gear from those companies could be used by Beijing for espionage and to steal commercial secrets.

Instead, U.S. carriers have to use equipment from non-Chinese companies. The Federal Communications Commission, which oversees the program, would then reimburse the carriers from a pot of $1.9 billion intended to cover their costs. Similar rip-and-replace efforts are taking place elsewhere. In Europe, where Huawei products have been a key part of telecom networks, carriers in Belgium, Britain, Denmark, the Netherlands and Sweden have also been swapping out the Chinese equipment because of security concerns, according to Strand Consult, a research firm that tracks the telecom industry. "Rip-and-replace was the first front in a bigger story about the U.S. and China's decoupling, and that story will continue into the next decade with a global race for A.I. and other technologies," said Blair Levin, a former F.C.C. chief of staff and a fellow at the Brookings Institution.

But cleansing U.S. networks of Chinese tech has not been easy. The costs have already ballooned above $5 billion, according to the F.C.C., more than double what Congress appropriated for reimbursements. Many carriers also face long supply chain delays for new equipment. The program's burden has fallen disproportionately on smaller carriers, which relied more on the cheaper gear from the Chinese firms than large companies like AT&T and Verizon. Given rip-and-replace's difficulties, some smaller wireless companies now say they may not be able to upgrade their networks and continue serving their communities, where they are often the only internet providers. "For many rural communities, they are faced with the disastrous choice of having to continue to use insecure networks that are ripe for surveillance or having to cut off their services," said Geoffrey Starks, a Democratic commissioner at the F.C.C.

Last month, Senator Deb Fischer, a Republican of Nebraska, introduced a bill to close the gap in rip-and-replace funding for carriers... In January, the F.C.C. said it had received 126 applications seeking funding beyond what it could reimburse. Lawmakers had underestimated the costs of shredding Huawei and ZTE equipment, and new equipment and labor costs have risen. The F.C.C. said it could cover only about 40 percent of the expenses. Some wireless carriers immediately paused their replacement efforts. "Until we have assurance of total project funding, this project will continue to be delayed as we await the necessary funding required to build and pay for the new network equipment," United Wireless of Dodge City, Kansas, wrote in a regulatory filing to the F.C.C. in January.

An anonymous reader quotes a report from Ars Technica: After the release of Apple's AirTags, Google suddenly has interest in the Bluetooth tracker market. The company has already quietly rolled out what must be the world's largest Bluetooth tracking network via Android's 3 billion active devices, and now trackers are starting to plug in to that network. Google is taking the ecosystem approach and letting various companies plug in to the Android Bluetooth tracking network, which has the very derivative name of "Find My Device." While these Bluetooth trackers are great for finding your lost car keys on a messy desk, they can also work as worldwide GPS trackers and locate items much farther away, even though they don't have GPS. The IDs of Bluetooth devices are public, so Tile started this whole idea of crowdsourced Bluetooth tracker location, called the "Tile Network." Every phone with the Tile app installed scans Bluetooth devices in the background and, using the phone GPS, uploads their last seen location to the cloud. This location data is only available to the person who owns the Tile, but every Tile user works to scan the environment and upload any Tiles the app can see. [...]

Now, third-party Bluetooth trackers for Android's network are starting to arrive. The two companies that have announced products are Chipolo and Pebblebee, both of which seem to be cloning the Tile line of products. Both offer normal keychain tracker tags and slim credit card format trackers. The worst habits of Tile include making completely disposable products because the batteries can't be changed, but it looks like our clones have mostly avoided that. All of Pebblebee's Find My Device products are rechargeable, which is great, while the Chipolo keychain tracker has a replaceable CR2032 battery. Only the Chipolo wallet tracker is disposable (boo!). All these tags will show up in the Find My Device app, right alongside your Android phones, headphones, and whatever else you have that plugs in to the network. They also have a speaker, like normal, so you can make them ring when you're near them. Both sets of products are up for preorder now.

An anonymous reader quotes a report from Ars Technica: Today, Fairphone, a company known for making smartphones that are meant to last, revealed its take on a user repair-friendly set of wireless, over-the-ear headphones. Like its smartphones, Fairphone's Fairbuds XL have a modular design with Fairphone promising easy spare parts access. However, Fairphone's currently unsure how long it will have parts for the cans in stock. And Fairphone is pulling back from its typical five-year warranty for phones, opting for two years, due to uncertainty around real-world longevity. Modular parts for the Fairbuds XL, which in true Fairphone fashion won't be sold in the US, include a headband cover that pops off to reveal the actual band, a cable connecting the speakers, and left and right speaker modules that allow users to replace a failed driver or wonky buttons.

As of this writing, the 11 modular parts aren't listed for sale, but The Verge reported a replacement battery will cost 19.95 euro, while ear cushions will cost 14.95 euro, and the three headband parts will be 19.95 euro for each. Most of the headset's electronics components, like the Bluetooth 5.1 module, reside in the left and right speaker parts, but Fairphone may start selling spare printed circuit boards, buttons, and microphones if demand warrants, The Verge said. Other headsets have offered replacement ear cushions and head straps before. However, the Fairbuds XL go further by enabling the entire frame of the headband to be swapped easily and encouraging battery replacements. There are wireless headsets with batteries you could manage to replace yourself, but doing so with the Fairbuds XL won't void the warranty.

Further, Fairbuds XL batteries are supposed to be easy to get through Fairphone, which will also sell Fairbuds XL modules through the Fairbuds App available on Play Store and App Store. A big sticking point for user repairability advocates is making spare parts accessible and affordable. Fairphone will also work with customers to provide support or contact with a repair partner if they don't want to perform repairs themselves and accept customers' unwanted components for reuse or recycling, according to The Verge.

Google has launched the Pixel 7a for $499, featuring a 6.1-inch OLED display at 90Hz, Tensor G2 chip with 8GB RAM, and 64MP main camera. The Pixel 7a nearly matches the flagship Pixel 7 on specs but starts at a lower price. GSMArena.com reports: Yes, the 7a marks several firsts for the Pixel a series. For starters, its 6.1" OLED display now runs at 90Hz, the same refresh rate as the Pixel 7 (though that one has a slightly larger 6.3" display). The resolution is FHD+ and you get Gorilla Glass 3 protection. Speaking of protection, the phone is rated IP67 for dust and water resistance. It has a metal frame and a plastic back -- Google notes that it used recycled aluminum, glass and plastic to build the phone. For example, the visor is 100% recycled aluminum. Available colors are Charcoal, Sea and Snow.

Another major upgrade is the switch to the Tensor G2 chipset, which is now paired with 8GB of LPDDR RAM (up from 6GB on the 6a) and 128GB UFS 3.1 storage. This is the same configuration as the Pixel 7, so the a-phone will be just as fast at the various computational tasks. Also, note that Google is promising 5 years of security updates. Among them is the Super Res Zoom (up to 8x), which is enabled by the new 64MP camera (up from 12MP). The ultra wide camera has a 13MP sensor and a f/2.2 lens that is blessed with Dual Pixel autofocus. The front-facing camera was also bumped up to 13MP with a fixed-focus lens (f/2.2). The rear camera can record 5K video at up to 60fps, the front one tops out at 4K at 30fps.

The Pixel 7a supports sub-6GHz and mmWave flavors of 5G, though only models for select regions will have mmWave enabled. This is a dual-SIM device with one physical nano-SIM and one eSIM. The 7a is powered by a 4,385mAh battery that supports up to 18W wired charging and for the first time on an a-phone wireless charging is available too -- also at 18W. Note that the port on the bottom is USB-C 3.2 Gen 2, but the retail box comes only with a USB C-to-C cable with USB 2.0 wiring (and you have to supply your own charger). You can order the Pixel 7a via the Google Store.

A Norwegian company named ENRX "wants to inductively charge electric vehicles with 200 kW while driving on a section of highway in Florida," according to the "electric mobility industry" news site electrive.com.

"A one-mile section of a four-lane highway near Orlando is to be electrified." ENRX has teamed up with the Central Florida Expressway Authority and the Aspire Engineering Research Center for an initiative to build a one-mile (1.6-kilometre) section on a four-lane highway near Orlando that will inductively charge the batteries of moving electric vehicles at 200 kW.

The principle is clear: the electric vehicle batteries are fitted with a special receiver pad and charged as they drive over the coils embedded in the road. In the process, the energy is transferred from these coils to the receiver pad mounted on the vehicle floor, which according to ENRX should provide "a safe, wireless power supply" even at motorway speeds. Advantages of the 'Next Generation Electric Roadway system' mentioned include interoperability, different output power levels for different vehicle and battery types, or user-defined distance between the ground and the vehicle. In addition, the system (on the infrastructure side) is supposed to be maintenance-free after installation...

"When you can charge while driving, range anxiety and frequent charging stops will be a thing of the past," says ENRX CEO Bjørn Eldar Petersen... "Dynamic charging can reduce the need for large battery capacities, allowing cars to be equipped with lighter and more affordable battery packs."

Sonos and Alphabet's Google will face off in a San Francisco federal trial on Monday over claims that Google copied Sonos' patented smart-speaker technology in wireless audio devices like Google Home and Chromecast Audio. From a report: The case is part of a sprawling intellectual property dispute between the former business partners that includes other lawsuits in the U.S., Canada, France, Germany and the Netherlands. Sonos has asked the court for $90 million in damages from Google in the San Francisco case, down from $3 billion after U.S. District Judge William Alsup narrowed the case, according to a Google court filing. Sonos alleges Google infringed two of its patents related to multi-room wireless audio. Google spokesperson Jose Castaneda said the case relates to "some very specific features that are not commonly used," and that Sonos "mischaracterized our partnership and technology."

The Washington Post's "Tech Friend" newsletter suggests some "tech fears you can stop worrying about." And it starts by reasuring readers, "You're fine using the WiFi in a coffee shop, hotel or airport. "Yes, it is safe," said Chester Wisniewski, a digital security specialist with the firm Sophos. Five or 10 years ago, it wasn't secure to use the shared WiFi in a coffee shop or another place outside your home. But now, most websites and apps scramble whatever you do online. That makes it tough for crooks to snoop on you when you're connected to public WiFi. It's not impossible, but criminals have easier targets.

Even Wisniewski, whose job involves sensitive information, said he connected to the WiFi at the airport and hotel on a recent business trip. He plans to use the WiFi at a conference in Las Vegas attended by the world's best computer hackers. Wisniewski generally does not use an extra layer of security called a VPN, although your company might require it. He avoids using WiFi in China.

You should be wary of public WiFi if you know you're a target of government surveillance or other snooping. But you are probably not Edward Snowden or Brad Pitt... For nearly all of us and nearly all of the time, you can use public WiFi without stress.
The newsletter also suggests we stop worrying about public phone chargers. ("Security experts told me that 'juice jacking' is extremely unlikely... Don't worry about the phone chargers unless you know you're being targeted by criminals or spies.")

Beyond that, "Focus your energy on digital security measures that really matter" — things like using strong and unique passwords for online accounts. ("This is a pain. Do it anyway.") And it calls two-factor authentication possibly the single best thing you can do to protect yourself online.

An anonymous reader quotes a report from The Register: Tokyo has five million Wi-Fi access points -- and that's 20 times what the city needs, because they're reserved for private use, according to NTT. The Japanese tech giant proposes sharing the fleet to cope with increased demand for wireless comms without adding more hardware. NTT says it's successfully tested network sharing with a scheme that starts by asking operators of Wi-Fi access points or other connections if they're open to sharing their bandwidth and allowing random netizens to connect. In return they get a share of revenue from those connections.

Under the scheme, netizens search for available networks and, as they connect, a contract would be executed allowing a link to be made. That contract would use Ethereum Proof of Authority to verify identities and initiate the back-end billing arrangements before allowing signed-up users and devices to join private networks. The operator of the Wi-Fi access point gets paid, the punter gets a connection, and everything's on a blockchain so the results can be read for eternity. [...] If this all scales, NTT estimates Tokyo won't need to add any more Wi-Fi access points or private 5G cells, even as demand for connectivity increases. The company also suggests it can enable networks to scale without requiring commensurate increases in energy consumption, and that spectrum will also be freed for other uses.

SpaceX and Rogers Communications struck a deal for satellite phone service in Canada -- a bid to bring emergency service to remote areas of the vast country that can't be reached through conventional wireless networks. From a report: The companies will use SpaceX's Starlink low-earth orbit satellites and begin with text service before adding voice and data coverage later, Rogers said in a statement. It didn't give a launch date for the new service. "In the future, these investments will deliver wireless connectivity, including access to 911, to even the most remote areas," Rogers Chief Executive Officer Tony Staffieri said in a statement. Staffieri was due to speak about the arrangement during his speech at the company's annual meeting on Wednesday.

An anonymous reader quotes a report from ZDNet, written by Steven Vaughan-Nichols: The latest Linux kernel is out with a slew of new features -- and, for once, this release has been nice and easy. [...] Speaking of Rust, everyone's favorite memory-safe language, the new kernel comes with user-mode Linux support for Rust code. Miguel Ojeda, the Linux kernel developer, who's led the efforts to bring Rust to Linux, said the additions mean we're, "getting closer to a point where the first Rust modules can be upstreamed."

Other features in the Linux 6.3 kernel include support and enablement for upcoming and yet-to-be-released Intel and AMD CPUs and graphics hardware. While these updates will primarily benefit future hardware, several changes in this release directly impact today's users' day-to-day experience. The kernel now supports AMD's automatic Indirect Branch Restricted Speculation (IBRS) feature for Spectre mitigation, providing a less performance-intensive alternative to the retpoline speculative execution.

Linux 6.3 also includes new power management drivers for ARM and RISC-V architectures. RISC-V has gained support for accelerated string functions via the Zbb bit manipulation extension, while ARM received support for scalable matrix extension 2 instructions. For filesystems, Linux 6.3 brings AES-SHA2-based encryption support for NFS, optimizations for EXT4 direct I/O performance, low-latency decompression for EROFS, and a faster Brtfs file-system driver. Bottom line: many file operations will be a bit more secure and faster.

For gamers, the new kernel provides a native Steam Deck controller interface in HID. It also includes compatibility for the Logitech G923 Xbox edition racing wheel and improvements to the 8BitDo Pro 2 wired game controllers. Who says you can't game on Linux? Single-board computers, such as BannaPi R3, BPI-M2 Pro, and Orange Pi R1 Plus, also benefit from updated drivers in this release. There's also support for more Wi-Fi adapters and chipsets. These include: Realtek RTL8188EU Wi-Fi adapter support; Qualcomm Wi-Fi 7 wireless chipset support; and Ethernet support for NVIDIA BlueField 3 DPU. For users dealing with complex networks that have both old-school and modern networks, the new kernel can also handle multi-path TCP handling mixed flows with IPv4 and IPv6. Linux 6.3 is available from kernel.org. You can learn how to compile the Linux kernel yourself here.

The Biden administration is beginning to plan for 6G wireless telecommunications, seeking to expand internet access while reasserting U.S. leadership in a sector where China has notched gains. WSJ: The White House on Friday will meet with corporate, government and academic experts to begin developing goals and strategies for the new 6G communications technology, which would have the ability to take cloud computing and the mobile internet to true global ubiquity, among other improvements. The next generation of telecom is still years away from deployment, but it could pave the way for global internet access still unavailable with the current 5G standard, which makes smartphone downloads and wireless hot-spot connections faster. Expanding access to the internet has been a priority for the Biden administration as part of its infrastructure initiatives. The 6G planning initiative also aims to reassert the leadership of the U.S. and its allies in telecommunications, where China has made gains thanks in part to careful nurturing of homegrown equipment manufacturing and increased participation in international standard-setting.

Google Fi, Google's cellular service, is getting its third rebrand in eight years. Ars Technica reports: First it was Project Fi, then Google Fi, and now it's "Google Fi Wireless." It also has its third logo, and this one's kind of clever: It's an "F" styled to look like sideways signal bars and in Google's trademark rainbow colors. There is also now a free trial mode. Google is harnessing the power of remotely configurable eSIMs to give anyone with an eSIM-compatible phone a seven-day/10GB free trial of Google Fi. That makes it easy to run around and test coverage.

Google Fi is a mobile virtual network operator (MVNO) -- a cellular reseller -- of T-Mobile's network, so whatever your T-Mobile coverage is like, that's what Fi is like. Google says that during the trial, "We'll give you a new Fi number to try out on your phone, but your current number will still work. During the trial, you can choose between Fi or your current network whenever you're calling, texting, or using mobile data." You'll need to enter a credit card for the trial, and after seven days, you'll be automatically billed on a $50 "Simply Unlimited" plan. Google notes you can cancel immediately (this is just one or two taps inside the app) and will still get the seven-day trial.

Alphabet's Google received a mixed ruling on Thursday from a San Francisco federal judge in a patent lawsuit brought by Sonos over wireless audio technology, failing to invalidate all of the patents before a trial but narrowing Sonos' claims. Reuters reports: The case, set for trial May 8, is part of a contentious intellectual property dispute between the former business partners over their smart speakers that includes lawsuits in the United States, Canada, France, Germany and the Netherlands. Sonos won a limited import ban on some Google devices from the U.S. International Trade Commission (ITC) last year, while Google has sued Sonos for patent infringement at the ITC and in California. [...]

Sonos accused Google in the San Francisco case of infringing four patents related to multi-room wireless speaker technology. U.S. District Judge William Alsup previously invalidated one of the patents and determined Google infringed another. Alsup found Thursday that a second Sonos patent was also invalid, but rejected Google's request to cancel the remaining two patents before trial. The judge also said Google did not infringe one of the surviving patents willfully, reducing Sonos' potential damages. Alsup also said he would hold a separate bench trial after the jury trial to determine whether Google's redesigned speakers infringe Sonos' patents.

The Free Software Foundation certifies products that meet their standards in regard to users' freedom, control over the product, and privacy. And they put out a new "Respects Your Freedom" certification on Thursday for ThinkPenguin's free software gigabit mini VPN router, the TPE-R1400.

From the FSF's announcement: This is ThinkPenguin's first device to receive RYF certification in 2023, adding to their vast catalogue of certified devices from previous years. As with previous routers from ThinkPenguin, the Free Software Gigabit Mini VPN Router ships with an FSF-endorsed fully free embedded GNU/Linux distribution called libreCMC. It also comes with a custom flavor of the U-Boot boot loader, assembled by Robert Call, the maintainer of libreCMC and a former FSF intern.

The router enables users to run their network connection through a VPN service, helping to simplify the process of keeping their communications secure and private. While ThinkPenguin offers a VPN service, users are not required to purchase a subscription to their service in order to use the router, and the device comes with detailed instructions on how to use the router with a wide variety of VPN providers.

"We're pleased to see ThinkPenguin continue with their commitment to bringing out devices that put software freedom as their first priority under the RYF program. The release of this router shows that ThinkPenguin is committed to the privacy and freedom of their users," said the FSF's executive director, Zoë Kooyman....

"The latest version of ThinkPenguin's VPN router lets its users take advantage of gigabit per second Internet connections while protecting their rights and privacy," said FSF's copyright and licensing associate, Craig Topham.

A Cornell University researcher has developed sonar glasses that "hear" you without speaking. Engadget reports: The eyeglass attachment uses tiny microphones and speakers to read the words you mouth as you silently command it to pause or skip a music track, enter a passcode without touching your phone or work on CAD models without a keyboard. Cornell Ph.D. student Ruidong Zhang developed the system, which builds off a similar project the team created using a wireless earbud -- and models before that which relied on cameras. The glasses form factor removes the need to face a camera or put something in your ear. "Most technology in silent-speech recognition is limited to a select set of predetermined commands and requires the user to face or wear a camera, which is neither practical nor feasible," said Cheng Zhang, Cornell assistant professor of information science. "We're moving sonar onto the body."

The researchers say the system only requires a few minutes of training data (for example, reading a series of numbers) to learn a user's speech patterns. Then, once it's ready to work, it sends and receives sound waves across your face, sensing mouth movements while using a deep learning algorithm to analyze echo profiles in real time "with about 95 percent accuracy." The system does this while offloading data processing (wirelessly) to your smartphone, allowing the accessory to remain small and unobtrusive. The current version offers around 10 hours of battery life for acoustic sensing. Additionally, no data leaves your phone, eliminating privacy concerns. "We're very excited about this system because it really pushes the field forward on performance and privacy," said Cheng Zhang. "It's small, low-power and privacy-sensitive, which are all important features for deploying new, wearable technologies in the real world." "The team at Cornell's Smart Computer Interfaces for Future Interactions (SciFi) Lab is exploring commercializing the tech using a Cornell funding program," adds Engadget. "They're also looking into smart-glasses applications to track facial, eye and upper body movements."

A video of the eyeglasses can be viewed here.

An anonymous reader shares a report: Back in 2019, Amazon announced Sidewalk, its low-bandwidth, long-range wireless network that uses the 900 MHz spectrum to connect Internet of Things (IoT) devices. It does this by creating a mesh network between Amazon's own Echo and Ring devices and sharing a small part of their owner's bandwidth. Ideally, this means Sidewalk will be able to connect devices that sit beyond the reach of a Bluetooth or Wi-Fi signal. Until now, though, only a select number of developers were able to build applications for the network. But that's changing today. The company is now shipping software and hardware development kits, as well as an easy-to-use test kit to test the available Sidewalk connectivity in your neighborhood.

Using the new test kit, developers will be able to check their local signal strength on a map to get a better sense of whether their devices will be able to connect to the network before they start working on a product. Amazon sent me one of these Ring-branded devices to try. Getting started with it involves little more than powering it up (it does have a battery for mobile usage) and logging into Amazon's web-based Sidewalk coverage service. From there, you can quickly see all of the raw data from the GPS-enabled test kit and get access to Amazon's U.S.-wide coverage map. To ensure user privacy, the coverage maps only show coverage within a 900m-by-900m square area. You will be able to see the exact location of your own device, but not other devices that report into the coverage map.

President Joe Biden made clear in his State of the Union address last month that as the US spends billions of dollars on new broadband connections, "we're going to buy American." But that aspiration is easier said than done. From a report: While there seems to be enough domestic fiber optic cable to connect communities, the electronic components such as routers that transform glass strands into data highways are made mainly in other countries. Cable providers, chip makers and wireless carriers are pleading for relief from the requirement to "buy American," saying they can't build new networks without foreign electronics. Otherwise the broadband buildup that Biden has set as a priority will be delayed by years as domestic sources are developed. "Everybody's sorting this out," said Michael Romano, executive vice president of NTCA-The Rural Broadband Association, a trade group. "It's not clear there's much, if any, American equipment that would satisfy Build America Buy America as it stands today." The Build America Buy America Act was enacted as part of the Infrastructure Investment and Jobs Act in 2021, and requires any infrastructure projects to use domestically sourced materials in order to receive federal assistance. That applies to the $42.5 billion Broadband Equity, Access and Deployment Program (BEAD), the flagship Biden initiative for building new networks to connect the 30 million Americans the administration estimates are without fast internet service.

Wemo, Belkin's smart home company, has paused development of Matter smart home devices. The Verge reports: In an email exchange, Jen Wei, Vice President of Global Communications and Corporate Development at Belkin, confirmed that, while the company remains convinced that "Matter will have a significantly positive impact on the smart home industry," it has decided to "take a big step back, regroup, and rethink'' its approach to the smart home. Wei went on to write that Wemo will bring new Matter products to market when it can find a way to differentiate them. It seems like Wemo might be concerned its smart home gear is becoming commoditized.

During CES 2022, Wemo announced it would bring Thread-compatible, Matter-compliant products to market when that new standard officially arrived. At the time, it was expected that the new connectivity standard, which promised to once and for all tear down the walls that have sequestered ecosystems away from one another, would launch in the middle of 2022 after two years of frustrating delays -- but Matter was again pushed back. As the year wore on, Wemo indeed updated a product to use Thread, the primary wireless protocol beneath the Matter standard that enables Wi-Fi-free local control of smart devices, and released a new Thread-compatible smart dimmer. Curiously, none of the new products -- a light switch, dimmer switch, plug, and a stick-on-the-wall three-button scene controller -- are slated for future Matter support. With the news, Wemo is tapping the brakes on Matter. And we probably won't get those updated versions it announced last year, either.

While the existing Thread devices from Wemo come with many of the important benefits of Matter -- exclusively local control with no direct access to your home network, fast operation, and easy setup that cuts out your Wi-Fi router as the middleman -- they lack the most crucial feature, the central problem Matter is to solve: near-universal smart home platform compatibility. These Thread devices only work with Apple HomeKit. But it's pretty hard for companies like Wemo to stand out in a field full of cheap IoT junk that costs half the price to do the same thing, as far as most normal people are concerned. Sure, maybe they're less secure, but many people willingly put an internet-connected microphone in their home, too. They probably don't care about the possible security issues with their light switch.

T-Mobile is buying Mint Mobile, the budget-friendly mobile carrier that's partially owned by Ryan Reynolds. The Verge reports: In a post published on Wednesday, T-Mobile announced that the deal's valued at up to $1.35 billion and comes as T-Mobile looks to build out its prepaid phone offering. The acquisition should close later this year and involves a 39 percent cash and 61 percent stock purchase of Mint's parent company, Ka'ena Corporation. The price could change, however, as it depends on Mint's performance.

Once the deal closes, Mint founders David Glickman and Rizwan Kassim will join T-Mobile to continue managing the brand, which T-Mobile says "will generally operate as a separate business unit." Meanwhile, Reynolds will also remain a part of Mint's branding, as T-Mobile says he will "continue on in his creative role on behalf of Mint." "I never dreamt I'd own a wireless company and I certainly never dreamt I'd sell it to T-Mobile," Reynolds said in a tweet. "Life is strange and I'm incredibly proud and grateful."

As noted by T-Mobile CEO Mike Sievert in a YouTube video posted on Wednesday, T-Mobile will retain the price of Mint's cheapest phone plan at $15 per month. The deal also includes Ka'ena's other companies, including Ultra Mobile, a prepaid carrier that offers international calling, and Plum, a wholesale wireless solutions provider. [...] By purchasing Mint, T-Mobile may be looking to claw back the customers it lost when it sold Boost Mobile to Dish as part of its merger with Sprint.

Samsung Electronics said Wednesday it expects to invest 300 trillion won ($230 billion) over the next 20 years as part of an ambitious South Korean national project to build the world's largest semiconductor manufacturing base near the capital, Seoul. From a report: The chip-making "mega cluster," which will be established in Gyeonggi Province by 2042, will be anchored by five new semiconductor plants built by Samsung. It will aim to attract 150 other companies producing materials and components or designing high-tech chips, according to South Korea's Ministry of Trade, Industry and Energy.

Samsung's new plants will be located near its existing domestic factories and will produce both computer memory chips used for storing data and higher-margin logic chips designed to perform a broader range of functions, the company said. A giant in the global memory business, Samsung is trying to expand its presence in advanced chips, anticipating that demand will soar in coming years with the adoption of new technologies such as 5G wireless networks, artificial intelligence and self-driving cars.
