Researchers from the startup Overview Energy have successfully demonstrated beaming power from a moving airplane to the ground using near-infrared light. It marks the first step toward space-based solar power satellites that could someday transmit energy from orbit to existing solar farms on Earth. IEEE Spectrum reports: Overview's test transferred only a sprinkling of power, but it did it with the same components and techniques that the company plans to send to space. "Not only is it the first optical power beaming from a moving platform at any substantial range or power," says Overview CEO Marc Berte, "but also it's the first time anyone's really done a power beaming thing where it's all of the functional pieces all working together," he says. "It's the same methodology and function that we will take to space and scale up in the long term." [...] Many researchers have settled on microwaves as their beam of choice for wireless power. But, in addition to the safety concerns about shooting such intense waves at the Earth, [Paul Jaffe, head of systems engineering] says there's another problem: microwaves are part of what he calls the "beachfront property" of the electromagnetic spectrum -- a range from 2 to 20 gigahertz that is set aside for many other applications, such as 5G cellular networks. "The fact is," Jaffe says, "if you somehow magically had a fully operational solar power satellite that used microwave power transmission in orbit today -- and a multi-kilometer-scale microwave power satellite receiver on the ground magically in place today -- you could not turn it on because the spectrum is not allocated to do this kind of transmission." Instead, Overview plans to use less-dense, wide-field infrared waves. Existing utility-scale solar farms would be able to receive the beamed energy just like they receive the sun's energy during daylight hours. So "your receivers are already built," Berte says. The next major step is a prototype demonstrator for low Earth orbit, after which he hopes to have GEO satellites beaming megawatts of power by 2030 and gigawatts by later that decade. Plenty of doubts about the feasibility of space-based power abound. It is an exotic technology with much left to prove, including the ability to survive orbital debris and the exorbitant cost of launching the power stations. (Overview's satellite will be built on earth in a folded configuration and it will unfold after it's brought to orbit, according to the company). "Getting down the cost per unit mass for launch is a big deal," Jaffe says. "Then, it just becomes a question of increasing the specific power. A lot of the technologies we're working on at Overview are squarely focused on that."

An anonymous reader quotes a report from Ars Technica: The Federal Communications Commission plans to authorize a new category of wireless devices in the 6 GHz Wi-Fi band that will be permitted to operate at higher power levels than currently allowed. The FCC will also consider authorizing higher power levels for certain wireless devices that are only allowed to operate indoors. The FCC said it scheduled a vote for its January 29 meeting on an order "to create a new category of unlicensed devices... that can operate outdoors and at higher power than previously authorized devices." These so-called Geofenced variable power (GVP) devices operating on the 6 GHz band will "support high data rates suitable for AR/VR, short-range hotspots, automation, and indoor navigation," and "overcome limitations of previous device classes by allowing higher power and outdoor mobility," the FCC said. They will be required to work with geofencing systems to avoid interference with fixed microwave links and radio astronomy observatories. FCC Chairman Brendan Carr attributed the FCC's planned action to President Trump in a press release titled, "President Trump Unleashes American Innovation With 6 GHz Win." That's consistent with Carr's relatively new stance that the FCC takes orders from the president, despite his insisting during the Biden era that the FCC must operate independently from the White House. While many of Carr's regulatory decisions have been criticized by consumer advocates, the 6 GHz action is an exception. Michael Calabrese, of New America's Open Technology Institute, told Ars that "increasing the power levels for Wi-Fi connections to peripheral devices such as AR/VR is a big win for consumers" and a change that has been "long advocated by the Wi-Fi community." Carr said that the FCC "will vote on an order that expands unlicensed operations in the 6 GHz band so that consumers can benefit from better, faster Wi-Fi and an entirely new generation of wireless devices -- from AR/VR and IoT to a range of innovative smart devices. [It] will do so through a set of forward-looking regulations that allow devices to operate at higher power while protecting incumbent users, including through geofencing systems." [...] A draft of the order said the planned "additional power will enable composite standard-power/LPI access points to increase indoor coverage and provide more versatility to American consumers." The FCC will also seek comment on a proposal to authorize LPI access points on cruise ships.

After more than two decades of promises and false starts in the mesh networking space, the smart home standards that Apple, Amazon and Google have each championed are finally set to escape their respective brand silos and work together in a single unified network. Starting January 1, 2026, Thread 1.4 becomes the Thread Group's only certified standard, bringing a crucial new capability called credential sharing. Devices from different manufacturers can now securely join the same mesh network -- an Amazon Echo Show and an Apple HomePod mini in the same house will both be able to control the same Nanoleaf lightbulb. This marks a significant departure from Thread 1.3, released in 2022, where each brand's mesh network connected only to devices from that same brand. The Thread Group launched in 2014 as a coalition led by Arm, Google's Nest Labs, and Samsung, later welcoming Apple and Amazon into the fold. Thread 1.4 handles low-power smart home devices and sensors, but homes also need high-bandwidth connections for laptops and phones. Wi-Fi 7 mesh serves that purpose and the Matter protocol acts as a translation layer between the two different mesh networks. Both Wi-Fi 7 and Matter arrived in products on store shelves in 2025.

An anonymous reader quotes a report from the New York Times: A few years ago, Paul Wieland, a 44-year-old information technology professional living in New York's Adirondack Mountains, was wrapping up a home renovation when he ran into a hiccup. He wanted to be able to control his new garage door with his smartphone. But the options available, including a product called MyQ, required connecting to a company's internet servers. He believed a "smart" garage door should operate only over a local Wi-Fi network to protect a home's privacy, so he started building his own system to plug into his garage door. By 2022, he had developed a prototype, which he named RATGDO, for Rage Against the Garage Door Opener. He had hoped to sell 100 of his new gadgets just to recoup expenses, but he ended up selling tens of thousands. That's because MyQ's maker did what a number of other consumer device manufacturers have done over the last few years, much to the frustration of their customers: It changed the device, making it both less useful and more expensive to operate. Chamberlain Group, a company that makes garage door openers, had created the MyQ hubs so that virtually any garage door opener could be controlled with home automation software from Apple, Google, Nest and others. Chamberlain also offered a free MyQ smartphone app. Two years ago, Chamberlain started shutting down support for most third-party access to its MyQ servers. The company said it was trying to improve the reliability of its products. But this effectively broke connections that people had set up to work with Apple's Home app or Google's Home app, among others. Chamberlain also started working with partners that charge subscriptions for their services, though a basic app to control garage doors was still free. While Mr. Wieland said RATGDO sales spiked after Chamberlain made those changes, he believes the popularity of his device is about more than just opening and closing a garage. It stems from widespread frustration with companies that sell internet-connected hardware that they eventually change or use to nickel-and-dime customers with subscription fees. "You should own the hardware, and there is a line there that a lot of companies are experimenting with," Mr. Wieland said in a recent interview. "I'm really afraid for the future that consumers are going to swallow this and that's going to become the norm." [...] For Mr. Wieland, the fight isn't over. He started a company named RATCLOUD, for Rage Against the Cloud. He said he was developing similar products that were not yet for sale.
