An anonymous reader quotes a report from Engadget: Under Acting Chairwoman Jessica Rosenworcel, the Federal Communications Commission is seeking to create new rules targeting spam text messages. Like another recent proposed rulemaking from the agency, the policy would push wireless carriers and telephone companies to block the spam before it ever gets to your phone.

"We've seen a rise in scammers trying to take advantage of our trust of text messages by sending bogus robotexts that try to trick consumers to share sensitive information or click on malicious links," Rosenworcel said. "It's time we take steps to confront this latest wave of fraud and identify how mobile carriers can block these automated messages before they have the opportunity to cause any harm."

At its Fall Mac event today, Apple announced the new third-generation AirPods, featuring a slightly revamped design with shorter stems and touch-based "force sensor" and support for spatial audio. Ars Technica reports: The new AirPods retain their usual hard plastic finish and do not have in-ear tips like the AirPods Pro, though Apple says they are now officially IPX4-rated for sweat and water resistance. Apple says the earbuds have six hours of battery life and up to 30 hours when including the charging case. (That's compared to five and 24 hours, respectively, on the second-gen model.) The included case supports MagSafe and wireless charging, though the earbuds do not feature active noise cancellation or a transparency mode like their pricier siblings.

Though the second-gen AirPods were renowned more for their ease of use than their audio quality, Apple says it has updated them with a redesigned driver and an adaptive EQ feature that automatically tunes your music based on the AirPods' fit in your ear. The earbuds will also use Apple's spatial audio tech, which makes audio sound like it is coming from around the user's head. To help with that, the new AirPods support dynamic head tracking like the AirPods Pro and the over-ear AirPods Max. The third-gen AirPods cost $179 and are available to order online today, with in-store availability starting October 26. Notably, Apple will continue to sell the existing second-gen AirPods for $129 alongside the new pair.

Slashdot reader dkatana shares IoT Times interview with Dr. Johannes Springer, Director General for the 5G Automotive Association, an EU lobbying group pushing for the inclusion of short-range 5G wireless technology in autonomous vehicles for vehicle-to-vehicle communications. Springer describes some of the services already being tested (like in Hamburg, Germany, where even traffic lights can communicate with vehicles for "optimal speed advisories" for avoiding red lights): We have, for instance, an initiative in Europe called a European Data Task Force, or data task force for world safety. And in this activity, millions of vehicles are already sharing safety-related data between the different car manufacturers. Of course, this data sharing exists via cellular networks. One vehicle that detects, for instance, a black ice warning, or produces a black ice warning, sends this warning via the cellular networks to other vehicles. And this consensus, the data sharing via the cellular networks, creates a lot of benefits for other traffic participants, not, by the way, just the vehicles, but also to other vulnerable road users, cyclists, pedestrians, and so on...
But they also discuss the prospects for automous vehicles beyond highway/intercity driving — and the idea of restricting them in cities to dedicated "safe corridors": Of course, the whole thing starts on a broad scale with restricted areas... And also, the private car industry is going heavily in this direction. If you take, for instance, the example of valet parking, automated parking. So, the automated driving task is restricted to a parking spot, to a parking garage: you can leave your car in front of the parking garage, and the car finds the free parking space by itself. And the same upon returning the vehicle. So this is something which takes place in the city but within a restricted area.

Suppose it goes, for instance, to buses or something like that. In that case, you can also see two examples during the ITS World Congress, two different, let's say, technical setups, where automated driving buses happen in the city. One is in a, let's say, non-controlled environment, and the vehicle drives entirely on its own, yeah? So this is shown by Easy Drive, part of Continental, a company that produces these types of systems. Of course, there is still the need to have a backup driver in the bus, which directly destroys the business case for the bus operator. And secondly, the driving speed is relatively low; I think 30 kilometers per hour or something like that.

The second example is, which is shown by Siemens, called the Heat Project, where the whole environment is completely controlled by roadside infrastructure. You have cameras and all these things equipped at the road to assess the situation and things around the bus. Personally, I don't believe that it can happen in cities or other open urban areas. Maybe, of course, if you have an airport, it might be different. But we cannot afford the necessary infrastructure, let's say, for monitoring the situation around the vehicle in real-time, whether it's a bus or another vehicle. No city is willing to pay for such an infrastructure just for the benefit of autonomous driving. So I'm pretty sure that this will not happen.
In the comments on the original submission, long-time Slashdot reader Gravis Zero discounts this as the opinion of a lobbying group advocating for specific 5G technologies (rather than using WiFi for direct vehicle-to-vehicle and vehicle-to-infrastructure communication).

But for what it's worth, the IoT Times interviewer also says "I've been talking to some experts in smart cities and some vehicle manufacturers... They say that certain types of autonomous driving have been going around for some time... But they are mainly focusing on motorways and intercity driving. We still have many problems allowing full autonomous driving in cities because of the number of different things that can happen."

Elon Musk touted SpaceX's plan to use Starlink for in-flight Wi-Fi, saying in a tweet on Thursday that the service could add "low latency ~half gigabit connectivity in the air!" CNBC reports: Starlink is the company's plan to build an interconnected internet network with thousands of satellites, known in the space industry as a constellation, designed to deliver high-speed internet to consumers anywhere on the planet. SpaceX has launched 1,740 Starlink satellites to date, and the network has more than 100,000 users in 14 countries who are participating in a public beta, with service priced at $99 a month.

Airlines work with satellite broadband providers for inflight Wi-Fi, with Viasat and Intelsat -- the latter of which purchased Gogo's commercial aviation business -- two such companies that add connectivity on flights by airlines including Delta, JetBlue, American Airlines and United. But, while existing services use satellites in distant orbits, Starlink satellites orbit closer to the Earth and could boost the speeds that passengers see inflight. SpaceX Vice President Jonathan Hofeller earlier this year said that the company is "in talks with several" airlines about adding Starlink in-flight Wi-Fi, noting that it has an "aviation product in development." Hofeller also emphasized that Starlink "provides a global mesh," so that "airlines are flying underneath that global mesh have connectivity anywhere they go."

Palm probably wasn't a name you were expecting to hear from again, but to the surprise of many, the company recently posted some teasers on Twitter foreshadowing a new gadget coming out later this month. From a report: While Palm hasn't officially revealed detailed info about its upcoming release, the teaser pics in its tweets make it quite clear that Palm is prepping to release a new pair of wireless earbuds. And judging by the silhouette of the device in the background, it seems Palm has taken some inspiration from Apple's ubiquitous AirPods. For a company that's most well known for making phones and PDAs, the decision to move into the audio market might seem like a strange pivot, especially since the last time we saw something from Palm was in 2018 with the tiny Palm Phone. Unlike other smartphones, Palm basically bucked every modern phone trend when it made the Palm Phone, which was designed so that you would spend less time looking at your phone in order to focus more on the world around you, while still providing the essential smartphone functionality.

Apple is likely to slash its projected iPhone 13 production targets for 2021 by as many as 10 million units as prolonged chip shortages hit its flagship product. Bloomberg reports: The company had expected to produce 90 million new iPhone models in the last three months of the year, but it's now telling manufacturing partners that the total will be lower because Broadcom and Texas Instruments are struggling to deliver enough components [...]. The technology giant is one of the world's largest chip buyers and sets the annual rhythm for the electronics supply chain. But even with strong buying power, Apple is grappling with the same supply disruptions that have wreaked havoc on industries around the world. Major chipmakers have warned that demand will continue to outpace supply throughout next year and potentially beyond. Apple gets display parts from Texas Instruments, while Broadcom is its longtime supplier of wireless components. One TI chip in short supply for the latest iPhones is related to powering the OLED display. Apple also is facing component shortages from other suppliers.

An anonymous reader quotes a report from Motherboard: [O]rganizers and programmers with the Mycelium Mesh Project are [...] designing a decentralized, off-grid mesh network for text communications that could be deployed quickly during government-induced blackouts or natural disasters. Mesh networks, a form of intranet distributed across various nodes rather than a central internet provider, have the potential to decrease our collective reliance on telecommunication conglomerates like Spectrum and Verizon. During a civil unrest situation, government operatives could theoretically disconnect established commercial mesh networks by raiding activists' homes and destroying their nodes or super nodes. The Mycelium Mesh Project is addressing this potential weak link by developing a system that could be deployed at a moment's notice in non-locations, such as on abandoned buildings, tree tops, electric boxes and utility poles.

Nodes would be cheap, run independently of the power grid, and could be produced with materials that can be obtained locally. So far, the collective has successfully sent and received text messages across thirteen miles during field testing around Atlanta, Georgia with nodes powered by rechargeable batteries harvested from disposable vapes. [...] The Mycelium Mesh Project is still in its relatively early stages of development. Messages aren't encrypted -- a necessary feature for activists -- and the model isn't ready for long-range use. But developers are hopeful that their open-source model will promote cooperation amongst like-minded coders. "The network that we all use will work pretty much fine in 99.9% of the cases. But then when it doesn't, it's a real big problem," Marlon Kautz, an organizer and developer with the project, told Motherboard. "The authorities' control over our communications infrastructure can just completely determine what is politically possible in a situation where the future is really up for grabs, where people are making a move to change things in a serious and radical way."

"This is anti-capitalist work, which is non-commercial. We are not trying to start a business," Kautz explained. "We're explicitly trying to take advantage of open source type concepts. So not not only do we want the code that we're developing to be open source, but our entire production model will be."

Rivian held a three-day press event in Colorado last week where a number of journalists, including TechCrunch's Kirsten Korosec, were able to take the R1T electric truck for a spin. Today, the embargo lifted and we're able to hear about their experience." An anonymous reader shares an excerpt from Korosec's report: On its first try, Rivian produced the Goldilocks of pickup trucks. The Rivian R1T electric truck is neither too big nor small. It handles rock crawling and off-camber trails with ease, can zip from zero to 60 miles per hour on a dirt road in just a few seconds without the typical back-end slippage -- although there is an option to provide that drifting effect -- and it can crank through winding mountain roads, pushing the edge of each corner without body roll. It's loaded with the kind of interior and exterior touches that put it firmly in the premium zone -- and yet the Rivian R1T is no delicate flower.

The company's designers and engineers helped the truck steer clear of pretension by combining form and function from tip to tail. Some of the added surprises -- the location of functional details like tie-downs, an air compressor and outlets -- suggest that numerous Rivian employees tested the truck in real-world conditions, including camping, mountain biking and even more mundane tasks like grocery-fetching. The result is a vehicle that feels right for all seasons and ready for anything. And, importantly, it's a joy to drive.

On a press drive over three days, a near-production-spec R1T proved to be the electric truck none of us knew we needed. That's not to say every choice landed perfectly. There are a few hardware details and elements on the software user interface side of things that could use a nip here and a tuck there. I'm looking at you, odd notch that is maybe a pen holder, but certainly the soon-to-be dust collector by the wireless charging pad. To be clear, far more time and miles are required to provide a full review. Still, as a total package, the Rivian R1T impresses. [Continue reading to hear about Korosec's thoughts on the nuts and bolts, circuit, handling and performance, user interface(s), and hardware accessories.] For a technical in-depth review of the Rivian R1T, Quinn Nelson from Snazzy Labs has produced an excellent video explaining his thoughts on the driving dynamics, vehicle functions, user interface design, and more. Fair warning: it's nearly 30 minutes long.

What's in the future for VR headsets made by Valve, which launched the pricey, bulky, and impressive Valve Index in August 2019? The best information in the wild right now seems to be coming from Valve itself: data-mining discoveries and patent applications are adding up to something that looks like a brand-new Valve VR system with some form of built-in wireless functionality. From a report: Sources familiar with matters at Valve have confirmed to Ars that information in the wild is legitimate -- at least in terms of products being made within Valve's headquarters, even if those products don't ultimately see retail launches. A new, unclear "ism" This week's information roundup comes courtesy of VR industry reporter and YouTube channel host Brad Lynch, who received a tip after tracking months of Valve patent applications. The tip came in the form of a device code-named "Deckard," which is mentioned in SteamVR's publicly available branches from as far back as January. Ars can confirm the legitimacy of "Deckard" as a code-named device worked on inside of Valve's headquarters. The information gleaned by Lynch points to multiple iterations of this new code-named headset, including an updated "proof of concept" version referenced this June, along with the ability to activate a "Valve internal menu" that brings up two new SteamVR menu options. These options, dubbed "prism" and "standalone system layer," have yet to be activated in meaningful ways, so their names and meaning remain a matter of speculation. The latter term, "standalone," implies that the hardware might work all by itself -- as opposed to, say, being plugged into a computer or tracked by Valve's unwieldy SteamVR Tracking Boxes.

An anonymous reader shares a report from Daring Fireball, written by John Gruber: Chaim Gartenberg, writing for The Verge, "The Lightning Port Isn't About Convenience; It's About Control": "Notably absent from Apple's argument, though, is the fact that cutting out a Lightning port on an iPhone wouldn't just create more e-waste (if you buy Apple's logic) or inconvenience its customers. It also means that Apple would lose out on the revenue it makes from every Lightning cable and accessory that works with the iPhone, Apple-made or not -- along with the control it has over what kinds of hardware does (or doesn't) get to exist for the iPhone and which companies get to make them. Apple's MFi program means that if you want to plug anything into an iPhone, be it charger or adapter or accessory, you have to go through Apple. And Apple takes a cut of every one of those devices, too." Gartenberg summarizes a commonly-held theory here: that Apple is sticking with its proprietary Lightning port on iPhones because they profit from MFi peripherals. That it's a money grab.

I don't think this is the case at all. Apple is happy to keep the money it earns from MFi, of course. And they're glad to have control over all iPhone peripherals. But I don't think there's serious money in that. It's loose-change-under-the-couch-cushion revenue by Apple's astonishingly high standards. How many normal people do you know who ever buy anything that plugs into a Lightning port other than a USB cable? And Apple doesn't make more money selling their own (admittedly overpriced) Lightning cables to iPhone owners than they do selling their own (also overpriced) USB-C cables to iPad Pro and MacBook owners. My theory is that Apple carefully weighs the pros and cons for each port on each device it makes, and chooses the technologies for those ports that it thinks makes for the best product for the most people. "What makes sense for the goals of this product that we will ship in three years? And then the subsequent models for the years after that?" Those are the questions Apple product designers ask.

The sub-head on Gartenberg's piece is "The iPhone doesn't have USB-C for a reason". Putting that in the singular does not do justice to the complexity of such decisions. There are numerous reasons that the iPhones 13 still use Lightning -- and there are numerous reasons why switching to USB-C would make sense. The pro-USB-C crowd, to me, often comes across as ideological. I'm not accusing Gartenberg of this -- though it is his piece with the sub-head claiming there's "a" singular reason -- but many iPhones-should-definitely-use-USB-C proponents argue as though there are no good reasons for the iPhone to continue using Lightning. That's nonsense. To be clear, I'm neither pro-Lightning nor pro-USB-C. I see the trade-offs. If the iPhones 13 had switched to USB-C, I wouldn't have complained. But I didn't complain about them not switching, either. You'll note that in none of my reviews of iPad models that have switched from Lightning to USB-C in recent years have I complained about the switch. Apple, to my eyes, has been managing this well. But, if the iPhones 13 had switched to USB-C, you know who would have complained? Hundreds of millions of existing iPhone users who have no interest in replacing the Lightning cables and docks they already own. "In 15 generations of iPhones, Apple has changed the connector once. And that one time was a clear win in every single regard," adds Gruber. "Changing from Lightning to USB-C is not so clearly an upgrade at all. It's a sidestep."

Regardless of which side you take on this debate, it's inevitable that Apple iPhones will adopt USB-C. Last week, the executive arm of the European Union, the European Commission, announced plans to force smartphone and other electronics manufacturers to fit a common USB-C charging port on their devices. The rules are intended to cut down on electronic waste by allowing people to re-use existing chargers and cables when they buy new electronics. Unless Apple plans to skip out on the European market or pay a potentially steep fine for refusing to adopt the port, they'll likely give into the pressure and release a USB-C-equipped iPhone by the time this law goes into effect in late 2023 or 2024.

The FCC has sent out the first checks from its Emergency Connectivity Fund, an effort to help close the "homework gap" at schools by covering the cost of computers and internet services. From a report: Thousands of school districts, in every state plus D.C., Guam and Puerto Rico, will split this first $1.2 billion distribution, and there's still lots more to come. The problem they are looking to mitigate is the large number of students who, in an age when studying, homework and now even classes are all done online, lack a device or adequate internet connection to participate. This exacerbates an existing inequality, for these students often lack access to other resources and end up falling behind through no fault of their own. The ECF was conceived to combat this, and funded earlier this year as part of the big pandemic recovery bill. It's a $7 billion program in total, but the money is being distributed over time as schools and libraries make their formal requests, saying they need to cover the cost of this many tablets, or wireless hotspots, or broadband connections. The FCC seems to be picking up the bill as long as the request is reasonable and the paperwork is in order.

An anonymous reader quotes a report from NPR: It's neither a bird nor a plane, but a winged microchip as small as a grain of sand that can be carried by the wind as it monitors such things as pollution levels or the spread of airborne diseases. The tiny microfliers, whose development by engineers at Northwestern University was detailed in an article published by Nature this week, are being billed as the smallest-ever human-made flying structures.

The devices don't have a motor; engineers were instead inspired by the maple tree's free-falling propeller seeds -- technically known as samara fruit. The engineers optimized the aerodynamics of the microfliers so that "as these structures fall through the air, the interaction between the air and those wings cause a rotational motion that creates a very stable, slow falling velocity," said John A. Rogers, who led the development of the devices. "That allows these structures to interact for extended periods with ambient wind that really enhances the dispersal process," said the Northwestern professor of materials science and engineering, biomedical engineering and neurological surgery.

The wind would scatter the tiny microchips, which could sense their surrounding environments and collect information. The scientists say they could potentially be used to monitor for contamination, surveil populations or even track diseases. Their creators foresee microfliers becoming part of "large, distributed collections of miniaturized, wireless electronic devices." In other words, they could look like a swarm. "We think that we beat nature," Rogers said. "At least in the narrow sense that we have been able to build structures that fall with more stable trajectories and at slower terminal velocities than equivalent seeds that you would see from plants or trees."

The European Commission, the executive arm of the European Union, has announced plans to force smartphone and other electronics manufacturers to fit a common USB-C charging port on their devices. From a report: The proposal is likely to have the biggest impact on Apple, which continues to use its proprietary Lightning connector rather than the USB-C connector adopted by most of its competitors. The rules are intended to cut down on electronic waste by allowing people to re-use existing chargers and cables when they buy new electronics. In addition to phones, the rules will apply to other devices like tablets, headphones, portable speakers, videogame consoles, and cameras. Manufacturers will also be forced to make their fast-charging standards interoperable, and to provide information to customers about what charging standards their device supports. Under the proposal, customers will be able to buy new devices without an included charger. The proposals only cover devices using wired, not wireless, chargers, EU commissioner Thierry Breton said in a press conference, adding that "there is plenty of room for innovation on wireless." A spokesperson for the Commission subsequently confirmed to The Verge that a USB-C port is only mandatory for devices that charge using a cable. But, if a device charges exclusively via wireless, like Apple's rumored portless iPhone, there'd be no requirement for a USB-C charging port.

An anonymous reader shares a report: In January, Google's parent company, Alphabet, shut down Project Loon, an initiative exploring using stratospheric helium balloons to distribute wireless internet (an attempt to use solar-powered drones folded in 2017). However, some technology developed as a part of the Loon project remained in development, specifically the Free Space Optical Communications (FSOC) links that were originally meant to connect the high flying balloons -- and now that technology is actively in use providing a high-speed broadband link for people in Africa.

Sort of like fiber optic cables without the cable, FSOC can create a 20Gbps+ broadband link from two points that have a clear line of sight, and Alphabet's moonshot lab X has built up Project Taara to give it a shot. They started by setting up links in India a few years ago as well as a few pilots in Kenya, and today X revealed what it has achieved by using its wireless optical link to connect service across the Congo River from Brazzaville in the Republic of Congo and Kinshasa in the Democratic Republic of Congo. In 20 days, Project Taara lead Baris Erkmen says the link transmitted nearly 700TB of data, augmenting fiber connections used by local telecom partner Econet and its subsidiaries.

CIStud writes: Sonos announces price hikes for Arc, Amp, Roam, Sub, Five, One and One SL speakers citing chip shortage and supply chain. Sonos Arc's price is leaping by $100 from $799 to $899. Not every product will be seeing a large jump in price, as some products like the Sonos Roam are seeing increases of just $10. Other products receiving only small price increases include the Sonos One and Sonos One SL ($20 increase), while others are not seeing pricing changes whatsoever like the Sonos Move and Sonos Port. Speaking of the far-reaching impact of the global chip shortage, Google and Indian telecom operator Jio announced this week they are delaying the launch of their affordable smartphone aimed at 300 million users.

Long-time Slashdot reader Nkwe shares an article about AT&T's "Flying COW" drones — their Cell (tower) On Wings drone technology that's helped restore cellphone service after Hurricane Ida and other natural disasters.

"The device is a cell site situated on a drone engineered to beam wireless LTE coverage across an area of up to 40 square miles." The weather-resistant drone can withstand extreme conditions, and its thermal imaging can help search and rescue teams find people in buildings, tree cover, and thick smoke... The drone has the potential to hover over 300 feet and is connected by a tether attached to the ground.

When someone texts, calls, or uses data, the signal is sent to the drone and transferred through the tether to a router. The router pushes information through a satellite, into the cloud, and finally into the AT&T network. The tether also provides constant power to the Flying COW via a fiber, giving the drone unlimited flight time.

Its flying capabilities allow it to soar 500% higher than a terrestrial Cell-on-Wheels mast, expanding how far the signal reaches, though more drones can be added to widen the coverage area. The drone is small and versatile, making it easy to set up, deploy, and move during rapidly changing conditions, like firefighters chasing a wildfire.

Qualcomm says it's figured out a way to deliver lossless audio over Bluetooth, yielding quality that should be indistinguishable from uncompressed sources. And it's calling it aptX Lossless, the next generation of Qualcomm's proprietary audio format. From a report: Taking a "systems level approach," was the key, the company says, as it's "optimized a number of core wireless connectivity and audio technologies, including aptX Adaptive, which work together to auto detect and scale-up and are designed to deliver CD lossless audio when a user is listening to a lossless music file and the RF conditions are suitable." So, yes, there are a few caveats, and you'll need new hardware to get the full aptX Lossless experience -- that goes for the device you're streaming from (a phone, for instance), as well as your listening device, typically a pair of headphones. Qualcomm says devices that support aptX Lossless are expected to be available in early 2022. Its key specs are: Supports 44.1kHz, 16-bit CD lossless audio quality
Designed to scale-up to CD lossless audio based on Bluetooth link quality
User can select between CD lossless audio 44.1kHz and 24-bit 96kHz lossy
Auto-detects to enable CD lossless audio when the source is lossless audio
Mathematically bit-for-bit exact
Bit-rate : ~1Mbps

What if your smartphone or laptop started charging as soon as you walked in the door? Researchers have developed a specially built room that can transmit energy to a variety of electronic devices within it, charging phones and powering home appliances without plugs or batteries. Scientific American: This system "enables safe and high-power wireless power transfer in large volumes," says Takuya Sasatani, a project assistant professor at the University of Tokyo's Graduate School of Engineering and lead author of the new study, which was published this week in Nature Electronics. The room relies on the same phenomenon as short-range wireless phone chargers: a metal coil, placed in a magnetic field, will produce an electric current. Existing commercial charging docks use electricity from a wall outlet to produce a magnetic field in a small area. Most recent smartphones are equipped with a metal coil, and when such a model) is placed on the dock, the interaction generates enough current to power the phone's battery. But today's commercial products have a very limited range. If you lift a phone off the dock or swathe it in a case that is too thick, the wireless power transfer ceases. But if a magnetic field filled a whole room, any phone within it would have access to wireless power.

"The prospect of having a room where a variety of devices could just receive power anywhere is really compelling and exciting," says Joshua Smith, a professor of computer science and electrical engineering at the University of Washington, who was not involved in the new study. "And this paper takes another step toward making that possible." In the study, the researchers describe a custom test room of about 18 cubic meters (roughly equivalent to a small freight container), which Sasatani built from conductive aluminum panels with a metal pole running down the middle. The team furnished the room with a wirelessly powered lamp and fan, as well as more prosaic items, including a chair, table and bookshelf. When the researchers ran an electric current through the walls and pole in a set pattern, it generated a three-dimensional magnetic field within the space. In fact, they designed the setup to generate two separate fields: one that fills the center of the room and another that covers the corners, thus allowing any devices within the space to charge without encountering dead spots.

By carrying out simulations and measurements, Sasatani and his co-authors found their method could deliver 50 watts of power throughout the room, firing up all of the devices equipped with a receiving coil that they tested: a smartphone, a light bulb and a fan. Some energy was lost in the transfer, however. Delivery efficiency varied from a low of 37.1 percent to a high of about 90 percent, depending on the strength of the magnetic field at specific points in the room, as well as the orientation of the device. Without precautions, running current through the room's metal walls would typically fill it with two types of waves: electric and magnetic. This presents a problem, because electric fields can produce heat in biological tissues and pose a danger to humans. So the team embedded capacitors, devices that store electric energy, in the walls. "It confines the safe magnetic fields within the room volume while confining hazardous parts inside all the components embedded inside the walls," Sasatani explains.

The biggest frustration among new car owners is that they can't get their car and smartphone to talk to one another, a new J.D. Power study finds. From a report: Consumers want their digital lives to follow them seamlessly in the car, which is why Apple CarPlay and Android Auto have become so popular. But if the wireless connection is glitchy, such features don't work, leaving car owners unhappy. "Owners are caught in the middle when vehicle and phone technologies don't properly connect," says Dave Sargent, vice president of automotive quality at J.D. Power.

1 in 4 problems cited by car buyers in the first 90 days of ownership involves infotainment, according to the J.D. Power 2021 Initial Quality Study (IQS), released Tuesday. For the first time in a decade, voice recognition is not the top problem; instead, it's Apple CarPlay/Android Auto connectivity, which worsened significantly, especially for those trying to connect wirelessly. About one-third of new cars now come with a built-in WiFi hub, which may or may not be compatible with a phone's operating system.

With Apple's latest iPhone just around the corner, reports suggest that it will include support for satellite communications, which consumers could use when terrestrial-based 4G and 5G are not available. The one getting most of the glory: Globalstar, the once-embattled satellite company. From a report: Globalstar shares shot up more than 40% at one point today. Shares in satellite companies Iridium and AST SpaceMobile also rose, more than 9% and 4%, respectively. One report tracks to TF International Securities analyst Ming-Chi Kuo, who, as MacRumors explained, discussed how the iPhone 13 lineup will feature hardware that is able to connect to low earth orbit (LEO) satellites, which could allow iPhone 13 users to make calls and send messages. The MacRumors report notes that the upcoming iPhone 13 supposedly features a customized Qualcomm X60 baseband chip that supports satellite communications; other smartphone brands reportedly are waiting until 2022 for the X65 baseband chip for turning on satellite communications functionality. While there are ample ways to support LEO connectivity in handsets, the bottom line is: The "simplest scenario" for providing LEO communications to users is if network operators work with Globalstar, according to the Kuo-based report. That raised some eyebrows, rightly so.
