An anonymous reader quotes a report from Ars Technica: Coming on the heels of the Neuralink announcement earlier this month -- complete with video showing a monkey playing Pong with its mind, thanks to a wireless brain implant -- researchers with the BrainGate Consortium have successfully demonstrated a high-bandwidth wireless brain-computer interface (BCI) in two tetraplegic human subjects. The researchers described their work in a recent paper published in the journal IEEE Transactions in Biomedical Engineering. As for the latest Neuralink breakthrough, Ars Science Editor John Timmer wrote last week that most of the individual pieces of Neuralink's feat have been done before -- in some cases, a decade before (BrainGate is among those earlier pioneers). But the company has taken two important steps toward its realization of a commercial BCI: miniaturizing the device and getting it to communicate wirelessly, which is harder than it sounds.

According to [John Simeral of Brown University, a member of the BrainGate consortium and lead author of the new paper], the BrainGate wireless system makes the opposite tradeoff -- higher bandwidth and fidelity -- because it wants all the finer details of the data for its ongoing research. In that regard, it complements the Utrecht and Neuralink systems in the BCI space. The new BrainGate system is based on the so-called Brown Wireless Device (BWD) designed by Arto Nurmikko, and it replaces the cables with a small transmitter that weighs about 1.5 ounces. The transmitter sits atop the user's head and connects wirelessly to an implant electrode array inside the motor cortex.

There were two participants in the clinical trial -- a 35-year-old man and a 65-year-old man -- both of whom were paralyzed by spinal cord injuries. They were able to continuously use the BCI for a full 24 hours, even as they slept, yielding continuous data over that time period. (The medical-grade battery lasts for 36 hours.) "We can learn more about the neural signals that way because we can record over long periods of time," said Simeral. "And we can also begin to learn a little bit about how people actually will use the system, given the freedom to do so." His team was encouraged by the fact that one of its study participants often asked if they could leave the wireless transmitters on a little longer. He has a head tracker he can use as a fallback, but several nights a week, he would choose to use the wireless BrainGate system because he liked it. "Right now, we typically decode or interpret the spiking activity from networks of neurons," said Simeral. "There are other encoding mechanisms that have been studied in the brain that have to do with how the oscillations in the brain are related to these spiking signals. There's information in the different oscillation frequencies that might relate to, for example, sleep state, attention state, other phenomenon that we care about. Without a continuous recording, you've surrendered the ability to learn about any of those. Learning how this all happens in the human brain in the home as people are behaving and having different thoughts requires having a broadband system recording from the human brain."

"The ability to potentially have individuals with disability using these systems at home on demand, I think is a great step forward," said Simeral. "More broadly, going forward, having more players in the field, having more funding, is important. I see nothing but great things from all of these interactions. For our own work, we see things on the horizon that were impossible five years ago, when there was essentially nobody in the corporate world interested in this space. So I think it's a very promising time."

An anonymous reader quotes a report from Gizmodo: Today, with the expansion of its Galaxy Upcycling at Home service (which is still in beta), users in the U.S., U.K., and South Korea will get access to an experimental feature in the SmartThings app designed to give an old Galaxy handset new life as a useful smart home accessory. By using the app to reconfigure the device's battery usage and optimization, Samsung says even older devices will still be able to deliver good longevity, while the phone's usual assortment of wireless connectivity features makes it easy to pair the phone with other devices in your home.

In the SmartThings app, Samsung provides a range of functions that an old smartphone can perform, including serving as a light sensor that can automatically turn on your smart lights or even your TV when it gets dark. Alternatively, you can also convert an old Galaxy phone into a sound sensor, with the phone using AI to detect common household noises like a barking dog, crying baby, or a knock on the door. In this way, you can also repurpose an old Samsung phone as a baby monitor of sorts [...]. And of course, even without much fiddling, upcycled Samsung phones can also be used as universal remotes, providing an easy way to control your streaming video box, play music on your smart speakers, control your lights, and more.

An anonymous reader quotes a report from Ars Technica: Charter Communications employees who have been on strike since 2017 are building an Internet service provider in New York City called "People's Choice." "People's Choice Communications is an employee-owned social enterprise launched by members of IBEW Local #3 to bridge the digital divide and help our neighbors get connected to the Internet during the COVID-19 pandemic," the ISP's website says. "We are the workers who built a large part of New York City's Internet infrastructure in the first place. We built out [Charter] Spectrum's cable system, until in 2017, the company pushed us out on strike by taking away our healthcare, retirement, and other benefits. It's now the longest strike in US history."

So far, People's Choice says it has completed rooftop antenna installations at two schools in the Bronx and installed "hardline connections to wireless access points connecting 121 units" at housing for survivors of domestic violence who have disabilities. A Gizmodo article said the system is equipped to offer minimum speeds of 25Mbps downstream and 3Mbps upstream, meeting a broadband standard that has been used by the Federal Communications Commission since 2015. "We have a big portion of most of the Bronx covered with our antenna," IBEW Local #3 steward Troy Walcott told Gizmodo. "Now we have to go building by building to let people know we're out there and start turning them on." "A few dozen Spectrum strikers have been actively involved in the installations, but Walcott expects that at least one hundred workers are waiting in the wings for the project to scale up," the Gizmodo article said. "We work in affordable housing, supportive housing, co-op housing, NYCHA [NYC Housing Authority], homeless shelters, and regular old apartment complexes," the webpage notes. You can fill out this form if you're interested in bringing broadband to your building.

"After we build out a network in your building, it transfers to cooperative ownership, so profits are returned to users," the People's Choice website says. "We are able to provide high-speed service in most cases for $10-$20/month. No more cable company ripping you off, and as an owner, you have a vote in policies like data privacy."

A federal judge tossed a $506.2 million damages award against Apple after ruling the iPhone maker should have been able to argue that patent owner Optis Wireless Technology was making unfair royalty demands, though he refused to throw out the liability finding. From a report: Optis and its partners in the case, PanOptis Patent Management and Unwired Planet, claimed that Apple's smartphones, watches, and tablets that operate over the LTE cellular standard were using its patented technology. U.S. District Court Judge Rodney Gilstrap said the jury should have been allowed to consider whether the royalty demand was consistent with a requirement that standard-essential patents be licensed on "fair, reasonable and non-discriminatory," or FRAND, terms. The patent trial in August, one of the few held during the pandemic, was part of an unusual sweep of verdicts in Texas that collectively resulted in $3.7 billion in damages against tech companies like Apple and Intel Corp. Apple was also hit with damages awards of $502.8 million in a decade-long battle over security communications technology, and $308.5 million in a case over digital rights management.

"Scientists have demonstrated the first human use of a wireless brain-computer interface, a potential breakthrough for people with paralysis," reports The Next Web (in a story shared by Slashdot reader Hmmmmmm): While traditional BCIs are tethered to users via cables, the new system — called BrainGate — replaces the cords with a small transmitter affixed atop a users' head. The unit then connects to an electrode array implanted in the brain's motor cortex. In a clinical trial, two participants with paralysis used the system to point, click, and type on a standard tablet computer. They both achieved similar typing speeds and point-and-click accuracy as those attained with wired systems.

The researchers say it's the first time a device has transmitted the full spectrum of signals recorded by a sensor in the brain's motor cortex.

In Myanmar, the junta's intensifying crackdowns on protesters in the street are mirrored by its rising restrictions online. Reuters: In the early hours of Feb. 1, Myanmar's military seized power in a coup that has ignited months of mass protests. The military junta's security forces have since killed more than 550 civilians in crackdowns on the pro-democracy protesters, including children. To try to suppress protests, the junta has imposed increasing restrictions on internet access, culminating in a near total shutdown as of April 2. That has made it extremely difficult for people to access information, upload videos of protests, or organize. These tactics have also crippled businesses and limited access to medical information during the coronavirus pandemic. A Myanmar junta spokesperson did not respond to calls seeking comment. At a March 23 press conference, spokesperson Zaw Min Tun said the junta had no immediate plans to ease internet restrictions because violence was being provoked online.

Protesters in Myanmar, who asked to stay anonymous, told Reuters they were terrified about being shut off from the world, with no way to broadcast news of the protests or of the army's killings to those outside of Myanmar. "We Myanmar people are in the dark now," said one young protester. "News from Myanmar is going to disappear," another added. Governments around the world are increasingly using internet restrictions during political crises as a tool to limit free expression and hide human rights abuses, according to data from the digital rights organization Access Now. The U.N. Human Rights Council has condemned such intentional disruptions as a human rights violation. "Whenever the internet is shut down during such critical moments we would hear or document or see reports of human rights abuses, and that is what is happening in Myanmar," said Felicia Anthonio, a campaigner with Access Now. "The government is cracking down on protesters to ensure they do not let the rest of the world know what is happening." Since the coup, the junta has ordered telecom companies to carry out dozens of shutdowns. These shutdowns targeted mobile and wireless internet, which is the only available internet for most in the country.

Verizon is recalling 2.5 million hotspot devices after discovering that the lithium ion battery can overheat, creating a fire and burning hazard. CNBC reports: The recall impacts Ellipsis Jetpack mobile hotspots imported by Franklin Wireless Corp and sold between April 2017 and March 2021. The affected models are labeled: MHS900L, MHS900LS and MHS900LPP. Verizon disclosed the recall Thursday alongside a notice from the U.S. Consumer Product Safety Commission (CPSC). A Verizon spokesperson said just over 1 million of the recalled devices are currently in use, meaning currently or recently used by customers.

According to the recall notice posted by the CPSC, Verizon had received 15 reports of the hotspots overheating. Six of those reports included incidents of fire damage to bedding or flooring and two involved minor burn injuries. Some of the hotspots were supplied to students by their schools to continue remote learning, according to the recall notice. Parents who received hotspots from their children's schools are advised to contact the schools about receiving a replacement. Other customers can request a replacement by going to ellipsisjetpackrecall.expertinquiry.com or calling 855-205-2627.

T-Mobile made a series of announcements Wednesday as part of its latest 'Un-carrier' initiative, including the official launch of its new home internet service, 5G phone offerings, and new investment in rural areas. From a report: T-Mobile Home Internet: After piloting a home internet service powered by its wireless network, T-Mobile Home Internet is now available to more than 30 million U.S. households. It costs $60 per month -- $10 more per month than the pilot program -- with average expected speeds of 100 Mbps for most customers and an included 4G/5G gateway device.

T-Mobile Hometown: The Bellevue, Wash.-based company will build hundreds of new retail stores and create 5,000 jobs in small U.S. towns. It is also adding "Hometown Experts" to towns where it can't build a store, and committing $25 million over five years to fund community development projects in rural areas.

5G phones: T-Mobile said it will let postpaid customers trade in any old phone in working condition for a new Samsung Galaxy A32 5G smartphone for free after 24 monthly bill credits.

Myanmar's military rulers have ordered internet service providers to shut down wireless broadband services until further notice, Reuters reported Thursday, citing sources. From the report: The instruction to halt wireless broadband services was relayed to employees of one provider in an email seen by Reuters, which did not state a reason for the order. It also said the current mobile internet shutdown would continue and by law it had to comply with the directive.

An anonymous reader quotes a report from Interesting Engineering: In a world-first, a team of researchers at the Georgia Institute of Technology has developed a small, 3D-printed rectifying antenna that can harvest electromagnetic energy from 5G signals and use it to power devices, in a way turning 5G networks into "a wireless power grid," according to a press release by the university. As explained in the Jan.12 issue of the journal Scientific Reports, the flexible Rotman lens-based rectifying antenna, in other words, rectenna, system can perform millimeter-wave harvesting in the 28-GHz band. Commonly used in radar surveillance systems to see multiple directions without moving the antenna system, the Rotman lens is especially important for beamforming networks. However, larger antennas, which unfortunately have a narrowing field of view, are needed to harvest enough power to supply devices, and this limits the usage.

The researchers solved this problem by using a system that has a wide angle of coverage. The Rotman lens provides 6 levels of view at the same time in a pattern shaped like a spider. By enabling this structure to map a set of selected radiation directions to an associated set of beam-ports, the lens is used as an intermediate component between the antennas and the rectifiers. This way, the electromagnetic energy collected by the antenna arrays from one direction is combined and fed into a single rectifier. This maximizes efficiency, enabling a system with both high gain and large beamwidth. The system achieved a 21-fold increase in harvested power compared with a referenced counterpart in demonstrations. It was also able to maintain identical angular coverage.

AT&T is lobbying against proposals to subsidize fiber-to-the-home deployment across the U.S., arguing that rural people don't need fiber and should be satisfied with Internet service that provides only 10Mbps upload speeds. Ars Technica reports: AT&T Executive VP Joan Marsh detailed the company's stance Friday in a blog post titled "Defining Broadband For the 21st Century." AT&T's preferred definition of 21st-century broadband could be met with wireless technology or AT&T's VDSL, a 14-year-old system that brings fiber to neighborhoods but uses copper telephone wires for the final connections into each home.

"[T]here would be significant additional cost to deploy fiber to virtually every home and small business in the country, when at present there is no compelling evidence that those expenditures are justified over the service quality of a 50/10 or 100/20Mbps product," AT&T wrote. (That would be 50Mbps download speeds with 10Mbps upload speeds or 100Mbps downloads with 20Mbps uploads.) AT&T said that "overbuilding" areas that already have acceptable speeds "would needlessly devalue private investment and waste broadband-directed dollars." "Overbuilding" is what the broadband industry calls one ISP building in an area already served by another ISP, whereas Internet users desperate for cheaper, faster, and more reliable service call that "broadband competition."

An anonymous reader quotes a report from Motherboard: All of the major carriers made a significant change to how SMS messages are routed to prevent hackers being able to easily reroute a target's texts, according to an announcement from Aerialink, a communications company that helps route text messages. The move comes after a Motherboard investigation in which a hacker, with minimal effort, paid $16 to reroute our text messages and then used that ability to break into a number of online accounts, including Postmates, WhatsApp, and Bumble, exposing a gaping hole in the country's telecommunications infrastructure.

"The Number Registry has announced that wireless carriers will no longer be supporting SMS or MMS text enabling on their respective wireless numbers," the March 25 announcement from Aerialink, reads. The announcement adds that the change is "industry-wide" and "affects all SMS providers in the mobile ecosystem." "Be aware that Verizon, T-Mobile and AT&T have reclaimed overwritten text-enabled wireless numbers industry-wide. As a result, any Verizon, T-Mobile or AT&T wireless numbers which had been text-enabled as BYON no longer route messaging traffic through the Aerialink Gateway," the announcement adds, referring to Bring Your Own Number.

For 30 years David E. Sanger has been covering foreign policy and nuclear proliferation for The New York Times — twice working on Pulitzer Prize-winning teams. But now as American and Chinese officials meet in Alaska, Sanger argues that China's power doesn't come from weapons — nuclear or otherwise: Instead, it arises from their expanding economic might and how they use their government-subsidized technology to wire nations be it Latin America or the Middle East, Africa or Eastern Europe, with 5G wireless networks intended to tie them ever closer to Beijing. It comes from the undersea cables they are spooling around the world so that those networks run on Chinese-owned circuits. Ultimately, it will come from how they use those networks to make other nations dependent on Chinese technology. Once that happens, the Chinese could export some of their authoritarianism by, for example, selling other nations facial recognition software that has enabled them to clamp down on dissent at home.

Which is why Jake Sullivan, Mr. Biden's national security adviser, who was with Secretary of State Antony J. Blinken for the meeting with their Chinese counterparts in Anchorage, warned in a series of writings in recent years that it could be a mistake to assume that China plans to prevail by directly taking on the United States military in the Pacific. "The central premises of this alternative approach would be that economic and technological power is fundamentally more important than traditional military power in establishing global leadership," he wrote, "and that a physical sphere of influence in East Asia is not a necessary precondition for sustaining such leadership...."

Part of the goal of the Alaska meeting was to convince the Chinese that the Biden administration is determined to compete with Beijing across the board to offer competitive technology, like semiconductor manufacturing and artificial intelligence, even if that means spending billions on government-led research and development projects, and new industrial partnerships with Europe, India, Japan and Australia... But it will take months, at best, to publish a broad new strategy, and it is unclear whether corporate America or major allies will get behind it.

An anonymous reader quotes a report from SlashGear: Nissan has found a second-life for old LEAF batteries inside mobile machines that help workers at Nissan factories worldwide. The old batteries are being used in automated guided vehicles or AGVs used for various tasks inside the manufacturing facilities, including delivering parts to workers on the assembly line.

AGVs are used as robotic mail carriers operating on magnetic tracks taking mail and parts exactly where they're needed on the assembly line. The idea is to use the AGV to deliver parts so the worker doesn't waste time searching for a component and can stay focused on installing parts. Nissan and other automotive manufacturers have found that AGVs are indispensable when it comes to saving time and increasing productivity on the assembly line. Nissan currently operates more than 4000 AGVs around the world at its various manufacturing facilities. The factories have a system that includes 30-second automatic quick charging to keep battery packs on the electric vehicles topped off and working correctly. AGVs also have sensors that keep them operating on a set route and allow them to stop when needed. They also have wireless communications capabilities that enable them to communicate with each other to avoid collisions.

Nissan says that it has been exploring ways to reuse old LEAF batteries since 2010. The first-generation LEAF used a 24-kilowatt hour battery pack made by combining 48 modules. Nissan said eight years ago, its engineers discovered a way to take three of those modules and repackage them to fit inside the AGV. Last year, the engineers began to repurpose used battery modules instead of using new ones to power the AGVs. The team also found the repurposed LEAF batteries last a lot longer thanks to their lithium-ion design compared to the lead-acid batteries used previously.

The FCC has slapped two Texas-based telemarketers for $225 million after making approximately 1 billion robocalls to people across the U.S. It marks the largest fine in its history. Engadget reports: They ran at least two businesses that illegally spoofed other companies to try and sell people on short-term insurance plans, claiming they were from well-known providers like Cigna. One of the people involved in the scheme admitted to making "millions" of robocalls per day, even going so far as to go out of his way to call numbers on the Do Not Call list because he believed it would be more profitable to do so. According to the FCC, "a large portion" of the more than 23.6 million health insurance robocalls that crossed US wireless networks in 2018 came from Rising Eagle, one of the companies the two telemarketers ran.

Regulators decided the next U.S. 5G airwaves auction will offer frequencies in portions covering millions of people, a plan backed by wireless giants thirsty for spectrum and opposed by cable providers leery of expensive bidding. From a report: The Federal Communications Commission with a 4-0 vote set rules for the sale that's to begin in October. It'll follow an airwaves auction that drew a record $81 billion in bids as companies race to establish next-generation ultrafast 5G wireless service. "We take action that will move us closer to 5G service that is fast, secure, reliable, and most importantly available everywhere in the country," FCC Acting Chairwoman Jessica Rosenworcel said as the agency voted at its monthly meeting in Washington.

Microsoft has once again reiterated that VR support for Xbox was not a focus for the company, following reports earlier today that hinted it was working on a VR headset compatible with the Xbox Series X/S. The Verge reports: The rumor first surfaced after IGN Italy reported that some Italian Xbox users received messages, which translated to "[a]n update for the VR headset is available" and "[u]pdate VR headset," when connecting the recently released Xbox Wireless Headset to their Xbox Series X or Series S consoles. A Microsoft representative told The Verge that "the copy in this error message is inaccurate due to a localization bug," while again reiterating that "VR for console is not a focus for us at this time."

Microsoft has yet to explore the VR space for its Xbox consoles. In 2018, the company pulled back on plans to support virtual reality headsets for Xbox in 2018, explaining that it wanted to focus "primarily on experiences you would play on your TV." In late 2019, Xbox boss Phil Spencer tweeted out that although he played "some great VR games" such as Half-Life: Alyx, console VR was not Xbox's focus ahead of the Xbox Series X / S release.

Huawei will begin charging mobile giants like Apple a "reasonable" fee for access to its trove of wireless 5G patents, potentially creating a lucrative revenue source by showcasing its global lead in next-generation networking. From a report: The owner of the world's largest portfolio of 5G patents will negotiate rates and potential cross-licensing with the iPhone maker and Samsung Electronics, Chief Legal Officer Song Liuping said. It aims to get paid despite U.S. efforts to block its network gear and shut it out of the supply chain, but promised to charge lower rates than rivals like Qualcomm, Ericsson AB and Nokia Oyj. Huawei should rake in about $1.2 billion to $1.3 billion in patent and licensing fees between 2019 and 2021, executives said without specifying which of those stemmed from 5G. It's capping per-phone royalties at $2.50, according to Jason Ding, head of Huawei's intellectual property department. China's largest technology company by revenue wants a seat at the table with tech giants vying to define the rapidly evolving field of connected cars, smart homes and robotic surgery. Battles are unfolding over who profits from 5G that may dwarf the size and scope of the tech industry's first worldwide patent war -- the one over smartphones. But having only just become a major player in 5G standards boards, Huawei is now grappling with U.S. sanctions that have all but crippled its smartphone business and threaten to hamstring its networking division abroad.

T-Mobile this week pledged that 200 million people in the U.S. will have access to a fast version of 5G wireless service by the end of the year, a far larger number than can be expected from AT&T or Verizon. From a report: Long the upstart challenger, T-Mobile has a strong network story when it comes to 5G, thanks to its possession of a key swath of mid-band spectrum -- which offers a good balance of faster speed and decent coverage compared to other chunks of airwaves. Each of the major carriers is making fresh 5G commitments this week, increasing the number of people they hope to reach with different flavors of the high-speed wireless technology.

Verizon detailed its 5G plans on Wednesday, including how it plans to use the $53 billion in spectrum it bought in a recent government auction as the airwaves become available. It plans to offer midband service in 46 markets this year, per CNET. AT&T holds its investor event Friday. It has been faster than Verizon at rolling out broad 5G coverage, but not as fast as T-Mobile. Also, like Verizon, it is relying on just-acquired midband spectrum to build out its network.

The global wireless industry is planning to allow tens of thousands of international visitors to congregate for its flagship event in Barcelona in June, more than a year after it was axed due to the pandemic. From a report: The GSMA trade body said everyone present will have to show a negative Covid-19 result to access the Fira Gran Via venue and repeat the test every 72 hours. Rapid testing centers will be made available on site and organizers are considering using hotels for more. Additional measures being put in place for one of Europe's most important business gatherings include a new contact tracing mobile app, real-time occupancy monitoring, improved air conditioning at the venue, and an increased number of on-site medical staff. "We believe that we can have around 45,000 to 50,000 attendees, as of today," Stephanie Lynch-Habib, the GSMA's chief marketing officer, said in an interview on Monday, adding that visitor interest is expected to be strong.
