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."

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.

An anonymous reader quotes a report from InterestingEngineering: The U.S. Air Force's Global Strike Command awarded a new $75.5 million contract to New York-based firm Persistent Systems. The aim is to build a unified security system for 400 operational Minuteman III intercontinental-range nuclear missile silos secured in remote areas throughout the U.S. It will be the world's largest wireless ad-hoc network, helping secure the U.S.'s nuclear arsenal amid growing concerns over global nuclear security.

Persistent Systems will roll out its Infrastructure-based Regional Operation Network (IRON) offering across three Air Force bases as part of the Regional Operating Picture (ROP) program. According to the company, the new security network will cover an area of 25,000 square miles (64,750 sq km), making it the world's largest wireless ad-hoc network. The IRON offering is an easy-to-deploy Integrated MANET Antenna System on fixed towers and poles. It will allow the U.S. Air Force to connect 75 operation centers and more than 1,000 Security Force vehicles. The ROP program will allow constant communication to an Operations Center via the towers. Meanwhile, the personnel at that Operations Center will know the exact location of any Security Forces on a digital map. Both will be able to share critical data seamlessly.

There may be a new ringtone in your life -- the urgent chime of a company-issued cell phone. From a report: In a throwback to the Blackberry era, telecom-service providers are seeing strong growth from companies handing out phones to employees. The phenomenon, which started during the pandemic, picked up recently thanks to new compliance policies around the use of WhatsApp and TikTok. It's provided a "tailwind" for subscriber gains at AT&T, Chief Financial Officer Pascal Desroches said at a conference this week. At the same event, T-Mobile US Inc. Chief Financial Officer Peter Osvaldik said his company's corporate customer count "grew every quarter in 2022."

The phones are more than just a corporate perk, said Gartner analyst Lisa Pierce. "It's also about control" -- a means of restricting or blocking applications and keeping corporate data secure, she said. Businesses, especially those in finance, have grown concerned about the security of their data, and the Securities and Exchange Commission and the Commodity Futures Trading Commission have stepped up their scrutiny over unauthorized private communication on applications such as WhatsApp and through personal email. Late last year, Congress, along with several states, banned China-owned TikTok from government employees' devices over national security concerns. This puts organizations in the position of either requiring their workers to remove apps from personal phones, or offering a secure second device. That second device helps explain how wireless carriers keep racking up millions of new subscribers long after the time when the mobile market passed saturation, with nearly every adult in the US owning at least one phone.

Apple is moving to in-house 5G modem chips for its 2024 iPhones, as far as the chief executive of Qualcomm -- which currently produces them for the tech giant -- is aware. From a report: "We're making no plans for 2024, my planning assumption is we're not providing [Apple] a modem in '24, but it's their decision to make," Cristiano Amon told CNBC at the Mobile World Congress in Barcelona. Apple's most recent iPhone 14 models use Qualcomm modems, but the company has been looking to go solo in the wireless connectivity market for some years.

It bought Intel's modem business in 2019 and there had been speculation it would begin using in-house parts this year. In an interview with CNBC's Karen Tso and Arjun Kharpal, Amon said Qualcomm had told investors back in 2021 that it did not expect to provide modems for the iPhone in 2023, but Apple then decided to continue for another year. Amon did not confirm whether Apple would pay Qualcomm QTL licenses if it moves to its own modems, but said royalty was "independent from providing a chip."

After widely rolling out an Energy Saver mode, Google has made four optimizations to Chrome for Mac that allows the browser to match the battery life you get when using Safari. 9to5Google reports: Google conducted testing on a MacBook Pro (13", M2, 2022 with 8 GB RAM running macOS Ventura 13.2.1) with Chrome 110.0.5481.100 in February of 2023. It showed that you can "browse for 17 hours or watch YouTube for 18 hours." For comparison, Apple touts up to 17 hours of wireless web browsing, and up to 20 hours Apple TV app movie playback. Meanwhile, Google uses this open-source benchmarking suite to run tests, and says that users will also "see performance gains on older models." Four changes from waking the CPU less often to tuning memory compression are specifically credited:

- Eliminating unnecessary redraws: "We navigated on real-world sites with a bot and identified Document Object Model (DOM) change patterns that don't affect pixels on the screen. We modified Chrome to detect those early and bypass the unnecessary style, layout, paint, raster and gpu steps. We implemented similar optimizations for changes to the Chrome UI."
- Fine tuning iframes: "...we fine-tuned the garbage collection and memory compression heuristics for recently created iframes. This results in less energy consumed to reduce short-term memory usage (without impact on long-term memory usage)."
- Tweaking timers: "...Javascript timers still drive a large proportion of a Web page's power consumption. As a result, we tweaked the way they fire in Chrome to let the CPU wake up less often. Similarly, we identified opportunities to cancel internal timers when they're no longer needed, reducing the number of times that the CPU is woken up."
- Streamlining data structures: "We identified data structures in which there were frequent accesses with the same key and optimized their access pattern."
