Sprint Corp sued AT&T late on Thursday, saying it is misleading consumers into believing that they are using fifth generation wireless network, known as 5G, a technology that has not yet been widely deployed. From a report: AT&T customers are seeing "5G E" logo on their mobile devices in over 400 markets. Although users are still using 4G network, AT&T is calling it 5G Evolution, a faster version of its existing network and a first step on the road to 5G. 5G can offer data speeds up to 50 or 100 times faster than 4G networks.

A comprehensive multi-year study by the non-profit Epicenter.works, comparing the 30 member countries of the European Union (EU) on net neutrality enforcement, has found that zero rating business practices by wireless carriers have increased the cost of wireless data compared to countries without zero rating. From a report: This directly contradicts all of the assertions by major wireless carriers that their zero rating practices are "free data" for consumers. Based on the evidence, zero rating not only serves as a means to enhance ISPs' power over the Internet, but it's also how they charge consumers more money for wireless service. Zero rating was originally going to be banned by the FCC under the General Conduct Rule, but when the FCC changed leadership the agency promptly green lighted and encouraged the industry to engage in zero rating practices before it began its repeal of net neutrality.

An anonymous reader quotes a report from The Guardian: Scientists at Massachusetts Institute of Technology (MIT) have created super-thin, bendy materials that absorb wireless internet and other electromagnetic waves in the air and turn them into electricity. The lead researcher, Tomas Palacios, said the breakthrough paved the way for energy-harvesting covers ranging from tablecloths to giant wrappers for buildings that extract energy from the environment to power sensors and other electronics. Details have been published in the journal Nature. Palacios and his colleagues connected a bendy antenna to a flexible semiconductor layer only three atoms thick. The antenna picks up wifi and other radio-frequency signals and turns them into an alternating current. This flows into the molybdenum disulphide semiconductor, where it is converted into a direct electrical current. [M]olybdenum disulphide film can be produced in sheets on industrial roll-to-roll machines, meaning they can be made large enough to capture useful amounts of energy.

Ambient wifi signals can fill an office with more than 100 microwatts of power that is ripe to be scavenged by energy-harvesting devices. The MIT system has an efficiency of between 30% and 40%, producing about 40 microwatts when exposed to signals bearing 150 microwatts of power in laboratory tests. "It doesn't sound like much compared with the 60 watts that a computer needs, but you can still do a lot with it," Palacios said. "You can design a wide range of sensors, for environmental monitoring or chemical and biological sensing, which operate at the single microwatt level. Or you could store the electricity in a battery to use later."

An update of the Bluetooth specification released today enables location services accurate to within 10 centimeters thanks to a new direction-finding capability. From a report: It arrives as a separate draft standard is nearly ready for an even faster and more accurate capability using ultra-wideband (UWB) radio, geared for use in smartphones. Bluetooth 5.1 describes ways to determine location using multiple antennas at either the transmitter or receiver. It uses measures of signal phase and amplitude to measure location, though profiles for application developers are still being finished.

In mid-March, the IEEE 802.15.4z standard for UWB should be in a stable draft form, opening the door for silicon designs. It enables location measures within a single centimeter and resolves in a nanosecond, a rate faster than Bluetooth. Smartphone giants Apple and Samsung have been active in the .4z meetings also attended by Huawei, leading some to suggest that the capability could be integrated in handsets within two years. NXP has also been active since the group started a year ago, giving rise to speculation that UWB could come into phones though an integrated NFC chip.

An anonymous reader shares an excerpt from a report via The Register: U.S. telecoms regulator the FCC has been accused of colluding with companies it is supposed to oversee in order to protect a controversial decision over new 5G networks. Chair of the House Commerce chair, Frank Pallone, has sent a letter to FCC chair Ajit Pai asking for copies of communications between the FCC and the big telcos regarding legal challenges to the regulator's 5G order, which forces local governments to charge a flat fee for installing new base stations. In the letter [PDF], Pallone strongly implies that the committee has heard from a whistleblower.

"It has come to our attention that certain individuals at the FCC may have urged companies to challenge the order the Commission adopted in order to game the judicial lottery procedure and intimated the agency would look unfavorably towards entities that were not helpful," it reads. In effect, the letter alleges that FCC staff -- almost certainly from Pai's office -- put pressure on the big telcos to challenge an order that is designed to benefit them as a way of gaming the judicial system so the case didn't end up in a court likely to overturn it.

The world's largest beer maker is using low-cost sensors and machine learning to predict when motors at a Fort Collins, Colo. brewery might malfunction. From a report: The Anheuser-Busch InBev SA plant was the first among the company's 350 beverage-making facilities to test whether wireless sensors that can detect ultrasonic sounds -- beyond the grasp of the human ear -- can be analyzed to predict when machines need maintenance. "You can start hearing days in advance that something will go wrong, and you'll know within hours when it'll fail. It's really, for us, very practical," said Tassilo Festetics, vice president of global solutions for the company.

The project began about six months ago when Mr. Festetics's team installed 20 wireless sensors across three packaging lines motors to measure vibrations. The sounds picked up are transmitted in real time and then compared to a normal, functioning engine's sounds, which serve as a baseline and allow the program to identify anomalies. A key advantage is that the sensors are non-invasive and don't need to be placed inside a machine. Sensors have been used for predictive maintenance in the past, but they were unable to transmit information in real time. Advances in processing data at the edge of the network, referred to as edge computing, enables companies to collect and analyze real-time sensor data from machines.

Applehu Akbar shares an old report raising a very good question for today's Congress: why not use today's videoconferencing tech to allow representatives to perform most Congressional activity from their home districts?" The ability to "work from home" would be especially beneficial during a government shutdown, like the one we're currently in, where money is tight and Congressional members are "sick and tired of Washington and don't want to show up anymore to vote." Slashdot reader Applehu Akbar writes: Because Congress people serve short terms and campaign largely on constituent service, they have to spend a large percentage of their time shuttling between home and Washington. Virtualizing most of their Washington presence would save fuel and energy while giving them more time with their constituents. In addition, there could be a long-term societal benefit in making Congress less vulnerable to lobbyist influence by keeping them out of the Beltway. Pearce told The Hill in a statement back in 2013: "Thanks to modern technology, members of Congress can debate, vote, and carry out their constitutional duties without having to leave the accountability and personal contact of their congressional districts. Keeping legislators closer to the people we represent would pull back Washington's curtain and allow constituents to see and feel, first-hand, their government at work. Corporations and government agencies use remote work technology; it's time that Congress does the same."

Phone maker Meizu has announced a new phone called "Zero," which doesn't have a headphone jack, or a charging port, or a physical SIM card slot, or any buttons, or a speaker grill. From a report: It doesn't even come with a SIM card slot and buttons you'd usually see on a phone -- the only elements that disturb the surface of its all-display, 7.8mm-thick ceramic unibody are its 12MP and 20MP rear cameras and two pinholes. One is a microphone, while the other is for hard resets. To make up for the lack of ports, Meizu Zero will support Bluetooth 5.0 and a wireless USB connectivity that will reportedly be able to transfer files as fast as the USB 3.0 standard can.

Zero's 5.99-inch QHD OLED screen will act as some sort of a giant speaker and earpiece replacement. It does have a big enough bezel for a 20MP front camera, but its fingerprint reader is completely on-screen. The device, which is powered by a Snapdragon 845 processor, relies on 18W wireless charging due to the lack of a charger port. And it may not have the usual physical buttons, but it does have pressure-sensing ones with haptic feedback on its borders.

Embedi security researcher Denis Selianin has discovered a vulnerability affecting the firmware of a popular Wi-Fi chipset deployed in a wide range of devices, such as laptops, smartphones, gaming rigs, routers, and Internet of Things (IoT) devices. According to Selianin, the vulnerability impacts ThreadX, a real-time operating system that is used as firmware for billions of devices. ZDNet reports: In a report published today, Selianin described how someone could exploit the ThreadX firmware installed on a Marvell Avastar 88W8897 wireless chipset to execute malicious code without any user interaction. The researcher chose this WiFi SoC (system-on-a-chip) because this is one of the most popular WiFi chipsets on the market, being deployed with devices such as Sony PlayStation 4, Xbox One, Microsoft Surface laptops, Samsung Chromebooks, Samsung Galaxy J1 smartphones, and Valve SteamLink cast devices, just to name a few.

"I've managed to identify ~4 total memory corruption issues in some parts of the firmware," said Selianin. "One of the discovered vulnerabilities was a special case of ThreadX block pool overflow. This vulnerability can be triggered without user interaction during the scanning for available networks." The researcher says the firmware function to scan for new WiFi networks launches automatically every five minutes, making exploitation trivial. All an attacker has to do is send malformed WiFi packets to any device with a Marvell Avastar WiFi chipset and wait until the function launches, to execute malicious code and take over the device. Selianin says he also "identified two methods of exploiting this technique, one that is specific to Marvell's own implementation of the ThreadX firmware, and one that is generic and can be applied to any ThreadX-based firmware, which, according to the ThreatX homepage, could impact as much as 6.2 billion devices," the report says. Patches are reportedly being worked on.

Digital license plates are now allowed in Michigan thanks to a new state law. It will join California and Arizona as one of the few states in the US that allow digital license plates, allowing drivers to register their cars electronically and eschew old-school metal plates. From a report: To be clear, digital license plates consist of displays covered in glass that are mounted onto a frame. They come with their own computer chips and wireless communication systems. Some of the benefits of using digital licenses versus old metal ones are the ability to display Amber alerts or stolen vehicle messages when needed, but they could also make it easier to digitally renew license plates over the years. That comes at a price, though. Currently, they cost $499 for a basic version, and $799 for a premium version that features a GPS navigation add-on.

Federal Communications Commission Chairman Ajit Pai refused to brief a Congressional committee Monday about mobile carriers' ability to share their subscribers' location data with third parties. From a report: House Commerce Committee Chairman Frank Pallone, Jr. (D-N.J.) asked Pai for an "emergency briefing" to explain why the FCC "has yet to end wireless carriers' unauthorized disclosure of consumers' real-time location data," and for an update on "what actions the FCC has taken to address this issue to date." Pai's FCC could take action, despite the 2017 repeal of the commission's broadband privacy rules. Phone carriers are legally required to protect "Customer Proprietary Network Information [CPNI]," and the FCC's definition of CPNI includes location data.

[...] Pai did not agree with Pallone, it turns out. "Today, FCC Chairman Ajit Pai refused to brief Energy and Commerce Committee staff on the real-time tracking of cell phone location[s]," Pallone said in a statement yesterday. "In a phone conversation today, his staff asserted that these egregious actions are not a threat to the safety of human life or property that the FCC will address during the Trump shutdown."

An anonymous reader quotes a report from Ars Technica: A free texting service used by teachers, students, and parents may stop working on the Verizon Wireless network because of a dispute over texting fees that Verizon demanded from the company that operates the service. As a result, teachers that use the service have been expressing their displeasure with Verizon. Remind -- the company that offers the classroom communication service -- criticized Verizon for charging the new fee. Remind said its service's text message notifications will stop working on the Verizon network on January 28 unless Verizon changes course. (Notifications sent via email or via Remind's mobile apps will continue to work.) The controversy cropped up shortly after a Federal Communications Commission decision that allowed U.S. carriers' text-messaging services to remain largely unregulated. Verizon says the fee must be charged to fund spam-blocking services. Remind said in a statement: "To offer our text-messaging service free of charge, Remind has always paid for each text that users receive or send. Now, Verizon is charging Remind an additional fee intended for companies that send spam over its network. Your Remind messages aren't spam, but that hasn't helped resolve the issue with Verizon. The fee will increase our cost of supporting text messaging to at least 11 times our current cost -- forcing us to end free Remind text messaging for the more than 7 million students, parents, and educators who have Verizon Wireless as their carrier."

Apple's operating chief said on Monday that Qualcomm refused to sell its 4G LTE processors to the company due to the companies' licensing dispute. According to CNET, that decision "had a ripple effect on how quickly Apple can make the shift to 5G." From the report: Qualcomm continues to provide Apple with chips for its older iPhones, including the iPhone 7 and 7 Plus, Apple COO Jeff Williams testified Monday during the US Federal Trade Commission's trial against Qualcomm. But it won't provide Apple with processors for the newest iPhones, designed since the two began fighting over patents, he said. And Williams believes the royalty rate Apple paid for using Qualcomm patents -- $7.50 per iPhone -- is too high.

The FTC has accused Qualcomm of operating a monopoly in wireless chips, forcing customers like Apple to work with it exclusively and charging excessive licensing fees for its technology. The FTC has said that Qualcomm forced Apple to pay licensing fees for its technology in exchange for using its chips in iPhones. The trial kicked off Jan. 4 in US District Court in San Jose, California. Testimony covers negotiations and events that occurred before March 2018 and can't encompass anything after that date. Apple is expected to only use Intel chips in its next iPhones, something that will make Apple late to the market for 5G phones. "By the 2019 holiday season, every major Android vendor in the U.S. will have a 5G phone available," reports CNET. "But Intel's 5G modem isn't expected to hit phones until 2020."

In a sea of 3D audio products and true-wireless earbuds, USB Type-C headphones were nowhere in sight at CES 2019. From a report: This absence isn't an accident, however. Rather, it's the deafening silence of an abandoned product category. While many looked to USB-C audio as the successor to the famed physical port, the available models aren't catching on, and they don't seem to be going anywhere. Their absence at CES 2019 doesn't paint a rosy picture of their future, either.

In general, it takes new standards quite a while to catch on, however, USB-C was thrust into the limelight far before its time. When Apple and Google ditched their headphone jacks, it limited the pool of audio peripherals to Bluetooth, or the very young USB-C category. Perhaps with a little more time and backing from a few more serious partners this could have matured alongside its older brother the TRRS plug, but it just wasn't to be. [...] One of the biggest issues that companies need to navigate pertains to source and peripheral device compatibility. USB Type-C headphone cables can either be active or passive -- or manifest as a dongle adapter. This inconsistency, paired with the fact that Audio Accessory Mode has yet to be universally supported, results in a barrage of compatibility issues. Hence why many users are unable to operate playback controls or use a headset's integrated microphone.

Apple's long-delayed AirPower wireless charging mat might finally be in production. According to a tweet from ChargerLAB, a "credible source" says that Apple has begun manufacturing the long-delayed wireless charging mat. The Verge reports: If true, it could mean that the long-overdue product could finally reach the hands of consumers before too much longer. Apple announced in September 2017, that it was introducing wireless charging capabilities in with the iPhone 8 and iPhone X, and gave a preview for its own wireless charging mat that would not only charge the iPhone, but its Apple Watch and AirPods. At the time, Apple didn't announce a price -- only that it was expected to be released sometime in 2018. That obviously didn't happen...

If what ChargerLAB says is accurate, that could mean that we'll see more about them in the near future. The site's tweet says that the devices are being manufactured at Luxshare Precision, which already manufactures Apple's AirPods and some cords. MacRumors translated a screenshot of ChargerLAB's WeChat conversation, in which the site's source expects the device be released soon. But given the charger's history of delays and technical challenges, it's probably best not to get one's hopes up just yet.

Global Energy Transmission (GET) co-founder William Kallamn says his wireless tech company has found a way to create a "power cloud" that can charge a drone while it's in flight. "The system comprises a ground-based power station with a frame of wires positioned in a roughly circular shape," reports Futurism. "When turned on, this creates an electromagnetic field in the air near the station. A drone equipped with a special antennae charges by flying into the range of the power cloud." From the report: Eight minutes of charge time translates to 30 minutes of flight. One of GET's power stations and two customized drones, each capable of carrying 7 kilograms (15.4 pounds), currently costs $120,000. It's hard to overstate the potential for drones to change our world, but for seemingly every positive use for the machines (package delivery, search and rescue operations), there's a negative one to consider (military weaponry, citizen surveillance). So, sure, a drone that never needs to land would be amazingly beneficial for moviemaking and sports coverage -- two uses Kallman notes in [an interview with entertainment vlogger David Fordham] -- but it's hard to imagine military or government officials wouldn't be highly interested in GET's drone charging tech as well.

During a small press gathering at CES in Las Vegas today, Nvidia CEO Jensen Huang said the company doesn't have any plans to resurrect the Shield Tablet, which launched in 2014, was last refreshed in 2015 and officially discontinued last year. "Shield TV is still unquestionably the best Android TV in the world," he said. "We have updated the software now over 30 times. People are blown away by how much we continue to enhance it." And more (unspecified) enhancements are coming, he said. TechCrunch reports: On the mobile side, though, the days of the Shield Tablet are very much over, especially now that the Nintendo Switch, which uses Nvidia's Tegra chips, has really captured that market. "We are really committed to [Shield TV], but on mobile devices, we don't think it's necessary," Huang said. "We would only build things not to gain market share. Nvidia is not a "take somebody else's market share company.' I think that's really angry. It's an angry way to run a business. Creating new markets, expanding the horizon, creating things that the world doesn't have, that's a loving way to build a business."

He added that this is the way to inspire employees, too. Just copying competitors and maybe selling a product cheaper, though, does nothing to motivate employees and is not what Nvidia is interested in. Of course, Huang left the door open to a future tablet if it made sense -- though he clearly doesn't think it does today. He'd only do so, "if the world needs it. But at the moment, I just don't see it. I think Nintendo did such a great job."

Verizon and T-Mobile are calling out AT&T for starting a shady marketing tactic that labeled its 4G network as a 5G network. "In an open letter, in which AT&T is not named directly, Verizon says in part 'the potential to over-hype and under-deliver on the 5G promise is a temptation that the wireless industry must resist,'" reports TechCrunch. Meanwhile, T-Mobile directly called out AT&T, tweeting a short video of someone putting a sticky note reading "9G" on top of their iPhone's LTE icon. The Verge reports: The promise comes right as AT&T has started to roll out updates doing exactly that: changing the "LTE" icon in the corner of select phones into an icon reading "5G E." One might assume that a "5G E" connection is the same thing as a "5G" connection, but it's not. AT&T is just pretending that the faster portions of its LTE network are 5G and is trying to get a head start on the 5G marketing race by branding it "5G Evolution." T-Mobile isn't happy about the marketing nonsense either. Its CTO, Neville Ray, wrote that AT&T was "duping customers."

Verizon says it's "calling on the broad wireless industry to commit to labeling something 5G only if new device hardware is connecting to the network using new radio technology to deliver new capabilities" (emphasis Verizon's). Kyle Malady, Verizon's chief technical officer, says Verizon will lead by example and that "a clear, consistent, and simple understanding of 5G" is needed so consumers don't have to "maneuver through marketing double-speak or technical specifications." Malady says Verizon will "not call our 4G network a 5G network if customers don't experience a performance or capability upgrade that only 5G can deliver." But that isn't the same thing as saying "we won't label our network 5G unless it's 5G." In fact, if you turn that sentence into a positive statement, it says "we will only call our 4G network a 5G network if it delivers a 5G-like experience." The Verge notes that Verizon "has also been misleading about its jump into 5G." Last year, Big Red bragged about launching the "world's first commercial 5G service," even though "it wasn't mobile; it was home internet service that just happened to be delivered wirelessly during the final stretch to a subscriber's home; and it didn't use the global 5G standard -- it used a rival 5G standard created by Verizon."

HP has just upped the refresh rate ante with its latest Omen 15. From a report: The company says it's the world's first gaming laptop with a 15.6-inch 1080p 240Hz IPS display, meaning it should stay ahead of even the quickest-shooting gamer. The laptop itself should also be able to keep up with the screen, as it's equipped with NVIDIA's latest mobile graphics, an 8th-generation Intel Core i7-8750H processor, 16GB of RAM and the latest 802.11ax wireless, aka "WiFi 6." The Omen 15 arrives in February at a starting price of $1,370.

Kenya runs on mobile phones. And yet, outside of major cities like Nairobi, the infrastructure for mobile telephony is lacking. That's why, in 2019, telecommunications provider Telkom Kenya will begin turning to high-altitude balloons built by the Alphabet subsidiary Loon to provide mobile phone service. From a report: "High-altitude balloons are actually a very reasonable way to approach this problem," says Sal Candido, Loon's head of engineering. "They're high, they cover a lot of ground, and there are no obstacles." It's simple "but for one thing," Candido adds -- each balloon needs to stay in place in the stratosphere, providing coverage for one area for hundreds of days before being replaced. Candido has been with Loon for five years, long before the effort -- then known as Project Loon -- graduated from X, the Alphabet research and development subsidiary, in July 2018. Candido initially worked on developing the balloons' navigation system, one of the key components needed to address the "one thing" keeping the idea from really lifting off.

The challenge of how to navigate the balloons properly has changed drastically during Candido's time at Loon, because over the years the understanding of how Loon would operate has changed drastically as well. [...] As Loon launched more balloons for its test flights -- the company has now logged over 30 million kilometers -- the engineering team realized that they could control where the balloons would travel. "Sometimes the most obvious answer comes to you much later on," Candido says. "Why don't the balloons just not leave the coverage area?" It turns out that this is possible, at least in most places, for reasonable durations.
