A new mobile data network -- accompanied by the quinfecta of a website, Medium post, white paper, dedicated subreddit and Discord channel -- quietly launched late Tuesday evening in San Francisco, promising a new way to exchange data anonymously and at high speeds without relying on legacy carriers, and at a cheaper price. From a report: The peer-to-peer open source wireless network called Pollen Mobile will incentivize its users with cryptocurrency to run their own mini cell towers and build out the network's coverage in the Bay Area where the service is initially launching. Anthony Levandowski's autonomous vehicle technology startup Pronto AI is launching the project. Levandowski, a polarizing, early pioneer in the autonomous vehicle industry, was pardoned last year by former President Donald Trump after being sentenced to 18 months in prison on one count of stealing trade secrets. Why is an autonomous vehicle startup creating a decentralized telecom incentivized by cryptocurrency? The catalyst of Pollen Mobile stemmed from Pronto's need for reliable, affordable mobile connectivity for its autonomous vehicles, Levandowski, who is still CEO of Pronto, told TechCrunch in a text message conversation. Pronto has been using Pollen internally for its AVs for months. "The reason why is simple, we needed reliable, affordable mobile connectivity for our AVs and we couldn't find it," he wrote. "So we built our own and realized it could be something others want." He added later: "Necessity is the mother of invention." Further reading: Anthony Levandowski Closes His Church of AI.

The nation's first stretch of road to wirelessly charge electric vehicles while they're in motion will begin testing next year in Detroit. Axios reports: "Electrified" roadways, which have wireless charging infrastructure under the asphalt, could keep EVs operating around the clock, with unlimited range -- a big deal for transit buses, delivery vans, long-haul trucks and even future robotaxis. In-road charging could also help pave the way for more widespread EV adoption by relieving consumers of the need to stop and plug in their cars. Electreon Wireless, an Israeli company whose plug-free charging infrastructure is already being tested in Europe, will deploy its first U.S. pilot in Detroit's Michigan Central district, a new mobility innovation hub near downtown. The electrified road, up to a mile long, would allow EVs to charge whether they're stopped or moving, and should be ready for testing in 2023. The state will contribute $1.9 million toward the project, which will also be supported by Ford Motor, DTE Energy and the city of Detroit.

Wireless EV charging systems use magnetic frequency to transfer power from coils buried underground to a receiver pad attached to the car's underbelly. An EV can pull into a designated parking place with an underground charging pad and add electricity the same way a smartphone charges wirelessly. Along an electrified road, vehicles with wireless charging capability can suck up energy as they drive, but for all other cars, it's an ordinary road. Wireless charging can add $3,000 to $4,000 to an already pricey EV, notes Meticulous Research. Electreon, which is working with carmakers to add receivers to their vehicles, aims to get the cost down to $1,000 or $1,500, Stefan Tongur, Electreon's vice president of business development, tells Axios. Users would likely access the feature through a monthly subscription, he noted.

After Alphabet shelved plans to build its own city and wound down the company in charge of the project, a group of former employees is carrying on its legacy. Bloomberg reports: Their startup, Sidewalk Infrastructure Partners LLC, is pursuing ambitious infrastructure projects, including the construction of specialized roads for self-driving cars, a sprawling smart grid project and the implementation of technology to help cities build 5G wireless networks. On Wednesday, the company plans to announce it raised $400 million from StepStone Group Inc., a private-market investment firm whose focuses include infrastructure. The deal values the business, known as SIP, at $1.25 billion, said a person familiar with the terms who asked not to be identified because they're private.

The idea for SIP came from Sidewalk Labs, the smart-city company that Google created in 2015. Sidewalk's flagship project was Quayside, a plan to develop a 12-acre site in Toronto to showcase various high-tech urban ideas. Building a city from scratch made sense as a way for Google's parent company to experiment with urban innovation, said Jonathan Winer, SIP's co-founder and co-chief executive officer. However, "There were a number of infrastructure systems that needed innovation now, not in 10 years," he said. In 2019, he and several other Sidewalk employees left to form SIP with a plan to build large, technically sophisticated projects. Alphabet and the Ontario Teachers Pension Plan funded the effort as its only investors.

[...] SIP is set up in an unusual way for a startup, operating sometimes as a sort of venture capital firm and other times as an operator building projects itself. This allows it to pursue a wider range of projects, Winer said. Among them is a 40-mile highway between Detroit and Ann Arbor, Michigan, designed for autonomous and connected vehicles. Michigan's state government unveiled the plan in 2020, and Winer said the first stretch of road will open this year. He's in talks with other states about similar developments, he said. SIP has also invested $100 million a project in California that uses smart thermostats and plugs to compensate customers for reducing their energy use at times of high demand. Much of SIP's business involves working with governments. [...] In addition to being an investor, Alphabet is an active participant in several SIP projects. Waymo, Alphabet's self-driving car unit, is on the advisory board of the Michigan highway project. Google's Nest thermostats work with the California program. "We benefit tremendously from Alphabet's technology and insight," said Winer. "And sometimes that insight translates into some kind of business transaction."

An anonymous reader quotes a report from Ars Technica: BlackBerry is adding another sad chapter to the downfall of its smartphone business. Today the company announced a sale of its prized patent portfolio for $600 million. The buyer is "Catapult IP Innovations Inc.," a new company BlackBerry describes as "a special purpose vehicle formed to acquire the BlackBerry patent assets." BlackBerry says the patents are for "mobile devices, messaging and wireless networking." These are going to be the patents surrounding BlackBerry's phones, QWERTY keyboards, and BlackBerry Messenger (BBM). BlackBerry most recently weaponized these patents against Facebook Messenger in 2018, which covered ideas like muting a message thread and displaying notifications as a numeric icon badge. BlackBerry -- back when it was called RIM -- was a veteran of the original smartphone patent wars, though, and went after companies like Handspring and Good Technology in the early 2000s.

If the name "Catapult IP Innovations" didn't give it away, weaponizing BlackBerry's patents is the most obvious outcome of this deal. According to the press release, Catapult's funding for the $600 million deal is just a $450 million loan, which will immediately be given to BlackBerry in cash. The remaining $150 million is a promissory note with the first payment due in three years. That means Catapult is now a new company with a huge amount of debt, no products, and no cash flow. Assuming the plan isn't to instantly go bankrupt, Catapult needs to start monetizing BlackBerry's patents somehow, which presumably means suing everyone it believes is in violation of its newly acquired assets.

Attackers have commandeered thousands of TracFone customers' phone numbers in recent weeks, forcing new owner Verizon Communications to improve safeguards less than two months after it took over the prepaid wireless provider. From a report: TracFone offers prepaid wireless service under several brands, including Straight Talk, Total Wireless and its namesake brand. Some customers of Straight Talk said they found their phone lines suddenly disconnected around the December holidays. "We were recently made aware of bad actors gaining access to a limited number of customer accounts and, in some cases, fraudulently transferring, or porting out, mobile telephone numbers to other carriers," TracFone said in a notice posted on its website this month. In some cases, customers said they discovered their lines had been moved without their permission to Metro, a unit of T-Mobile US. A T-Mobile spokeswoman said the company investigated and found "no fraud or data breach of any sort" on its side. The company added that such unauthorized transfers "are unfortunately an industrywide issue."

Verizon, which acquired TracFone in late November in a $6.25 billion deal, said it had added security protections to the recently acquired services to prevent such fraudulent transfers. For instance, the prepaid operators will now send customers a text message notification when a transfer request is made. A Verizon spokeswoman said the attack appeared to affect about 6,000 TracFone customers, a fraction of Verizon's roughly 24 million prepaid lines. "We have no reason to think that this was caused by anybody on the inside," the spokeswoman said. "You've got the bad actors out there constantly trying to find points of weakness," Matt Ellis, Verizon's finance chief, said Tuesday in an interview. "We've addressed that weakness."

About 90% of the U.S. commercial aircraft fleet is at least somewhat shielded from interference caused by new 5G wireless networks, the Federal Aviation Administration said Tuesday. From a report: The FAA expanded the roster of aircraft that it says can perform "most" low-visibility landings in the presence of the 5G radio waves to include several models of regional jets, according to a notice on the agency's website. The FAA approvals don't cover every plane at every airport, and are subject to revisions each month as the agency reviews the addition of new 5G cell towers, the agency said. They could also be limited if wireless companies increase power levels. New wireless phone service that began on Jan. 19 broadcasting on frequencies near those used by aircraft has prompted the FAA to raise concerns about radio interference. The latest action by the agency combined with an agreement by wireless companies to temporarily limit power levels and the placement of cell towers near airports has meant that the most severe impacts have been avoided for now.

An undersea fibre-optic cable which connects Tonga to the rest of the world was severed during the eruption of a volcano. From a report: New Zealand's ministry of foreign affairs says it could take more than a month to repair breaks in the 49,889km (31,000miles) of cable that serves the South Pacific. The undersea eruption - followed by a tsunami - led to Tonga's 110,000 people being cut off. A 2G wireless connection has been established on the main island, using a satellite dish from the University of the South Pacific. But the service is patchy, and internet services run slowly. The cable, which is operated by Tonga Cable, is believed to have broken about 37km (23 miles) offshore. According to Reuters, fault-finding conducted by the company in the aftermath of the volcano seemed to confirm a cable break.

he process of mending it is actually quite simple, according to principal engineer at Virgin Media, Peter Jamieson, who is also vice-chairman of the European Subsea Cable Association. "They will send a pulse of light from the island and a machine will measure how long it takes to travel and this will establish where the break is," he explained. Then a cable-repair boat will be sent to the location of the first break. It will use either an ROV (remotely-operated underwater vehicle) or a tool known as a grapnel (basically a hook on a chain) to retrieve the broken end. That will be re-joined to fresh cable on board the boat and then the same process will happen at the other end of the break. If all goes well, the whole process will take between five and seven days. It will take time to get a cable repair boat to the archipelago and the closest one is currently stationed in Port Moresby, Papua New Guinea - about 4,700km (2,900 miles) away. The specialised ship, The Reliance, serves more than 50,000km (31,000 miles) of cable in the South Pacific.

The FAA has announced that an "estimated 78 percent of the U.S. commercial fleet" have been cleared to land at airports with 5G C-band, even under low-visibility conditions. The Verge reports: The agency's statement comes after a week of controversy surrounding the rollout of AT&T and Verizon's upgraded cellular tech, which saw US airlines warning of "catastrophic disruption" to travel and shipping and some international airlines announcing they'd halt flights to some US airports. At issue are concerns that some radio altimeters won't properly ignore signals from the new 5G transmitters. While there are precautions that should keep this from happening, including creating buffer zones around airports, an incorrect altimeter reading could cause real problems during a low-visibility landing.

Given the high stakes, the FAA has said that only planes with altimeters that it has tested and cleared will be allowed to land in sub-optimal conditions at airports where the new 5G tech has rolled out. [...] On January 16th, the agency announced that it had cleared two altimeters, which it bumped up to five on Wednesday. It said the cleared altimeters were installed in "some" versions of planes like the Boeing 737, 747, and 777. The FAA changed that language on Thursday, saying that the 13 cleared altimeters should cover "all" Boeing 717, 737, 747, 757, 767, 777, 787, MD-10/-11, and Airbus A300, A310, A319, A320, A330, A340, A350, and A380 models. It also notes that "some" Embraer 170 and 190 regional jets are covered.

The FAA is still predicting that some altimeters won't pass the test and will be "too susceptible to 5G interference." Planes equipped with those models won't be allowed to land at airports with the new 5G tech in low-visibility conditions -- which could prevent airlines from scheduling any flights using those planes to airports of concern, given the unpredictability of weather and the disruption such a diversion would cause.

gollum123 shares a report from CNN: Major international airlines are canceling flights to the United States over aviation industry fears that 5G technology could interfere with crucial onboard instruments. But it's business as usual in Europe, where the latest generation of high speed mobile networks is being rolled out without a hitch. Why is there a potential problem in the United States, but not Europe? It comes down to technical details.

Mobile phone companies in the United States are rolling out 5G service in a spectrum of radio waves with frequencies between 3.7 and 3.98 GHz. The companies paid the US government $81 billion in 2021 for the right to use those frequencies, known as the C-Band. But in Europe, 5G services use the slower 3.4 to 3.8 GHz range of spectrum. The aviation industry is worried that US 5G service is too close to the spectrum used by radar altimeters, which is between 4.2 and 4.4 GHz. Europe does not face the same risk, according to the industry, because there is a much larger buffer between the spectrum used by radar altimeters and 5G.

There are other differences in how 5G is being rolled out, according to the US Federal Aviation Administration (FAA). Other countries are using lower power levels, restricting the placement of 5G antennas near airfields and requiring them to be tilted downward to limit potential interference with aircraft. In France -- cited by telecom carriers such as AT&T and Verizon as an example of 5G and aviation working seamlessly together -- the height of a 5G antenna and the power of its signal determine how close it is allowed to a runway and the flight path of an aircraft, according to a technical note from France's National Frequency Agency (ANFR). Antennas around 17 major French airports are also required to be tilted away from flight paths to minimize the risk of interference, the agency's director of spectrum planning and international affairs, Eric Fournier, told CNN.

Sweden's Ericsson has filed another set of patent infringement lawsuits against Apple in the latest salvo between the two companies over royalty payment for use of 5G wireless patents in iPhones. From a report: Both companies have already sued each other in the United States as negotiations failed over the renewal of a seven-year licensing contract for telecoms patents first struck in 2015. Ericsson sued first in October, claiming that Apple was trying to improperly cut down the royalty rates. The iPhone maker then filed a lawsuit in December accusing the Swedish company of using "strong-arm tactics" to renew patents. "Ericsson has refused to negotiate fair terms for renewing our patent licensing agreement, and instead has been suing Apple around the world to extort excessive royalties ... we are asking the court to help determine a fair price," an Apple spokesman said on Tuesday. Patent lawsuits are quite common among technology companies because every dollar saved could amount to significant amounts over the duration of the agreement, with companies such as Ericsson charging $2.50 to $5 for every 5G handset.

"Linux fans rejoice!" writes Hot Hardware. " Pine64's newest smartphone is officially available for pre-order." PinePhone Pro Explorer Edition pre-orders opened up Tuesday. Devices that are pre-ordered before January 18th will be shipped from Pine64's Hong Kong warehouse by January 24th and should arrive by early February.... According to Pine64, the PinePhone Pro Explorer Edition is the "fastest mainline Linux smartphone on the market." It uses a Rockchip RK3399S SoC that is composed of two ARM A72 cores (1.5GHz) and four A53 efficiency cores (1.5GHz)....

Consumers will also likely be pleased with the price of the device. The PinePhone Pro Explorer Edition currently rings in at $399 USD. The production run is purportedly "large" and interested consumers should therefore be able to easily purchase the device at this price.
Liliputing adds: While the PinePhone Pro has better hardware than the original PinePhone, Pine64 plans to continue selling both phones indefinitely. The first-gen phone will continue to sell for $150 to $200, offering an entry-level option for folks that want to experiment with mobile Linux, while the higher-priced PinePhone Pro should offer a hardware experience closer to what folks would expect from a modern mid-range phone....

In addition to the PinePhone Keyboard, the recently launched PinePhone wireless charging case, fingerprint reader case, and LoRa cases should all work with either phone.

But the new phone has a faster processor, more memory and storage, higher-resolution cameras, a higher-speed USB-C port and support for WiFi 5 and Bluetooth 4.1. And those features should make it a little more viable as a replacement for an iPhone or Android device... if you're comfortable running work-in-progress software.
They also add that "Thanks to the recent launch of the $50 PinePhone Keyboard, you can also think of the PinePhone Pro as a $400 phone that can be used as a $449 mini-laptop...."

And the Pine64 site's January update also points out that "Pico 8 Raspberry Pi port works on the PinePhone," adding "yes, it does run DOOM."

Vodafone Idea said on Tuesday it is giving the Indian government a 35.8% stake in the company after its board approved conversion of dues and spectrum auction instalments into equity to save the third-largest telecom operator in the country from collapsing. From a report: The operator, a joint venture between the British telecoms group Vodafone and local billionaire Kumar Mangalam Birla's conglomerate, has been attempting to avoid a collapse for several years after the arrival of Reliance Jio, which undercut the competitors with cheap data and free calls offering. Vodafone Idea, additionally, owed New Delhi dues of roughly $6.76 billion. Following the conversion into equity, Vodafone Group's shareholding will be diluted to 28.5% while Aditya Birla Group's will shrink to 17.8%. The Indian government will become the largest shareholder in the wireless telecom operator. [...] Tuesday's announcement comes months after the Indian government gave operators more time to pay dues on a two-decade dispute last year.

America's Federal Aviation Administration "has published the list of 50 airports around which it wants Verizon and AT&T to create '5G buffer' zones..." reports PC Magazine: The Department of Transportation previously asked Verizon and AT&T to delay the deployment of their C-Band networks from Dec. 5, 2021 to Jan. 5 due to concerns about interference affecting the altimeters used by commercial aircraft. Then on Jan. 2 the FAA asked the carriers to push back the debut of their C-Band networks again so it could investigate those safety risks.

The FAA said at the time that it would "identify priority airports where a buffer zone would permit aviation operations to continue safely while the FAA completes its assessments of the interference potential around those airports." Verizon and AT&T agreed to delay the launch of their C-Band networks for two weeks and respect the buffer zones designated by the FAA.

The administration says in its announcement that "the wireless companies agreed to turn off transmitters and make other adjustments near these airports for six months to minimize potential 5G interference with sensitive aircraft instruments used in low-visibility landings...." Reuters reports that the FAA's list was informed by Verizon and AT&T's coverage maps — in some cases "5G towers are far enough away that a natural buffer exists," the FAA says, according to the report — as well as a given airport's existing capabilities.
"Traffic volume, the number of low-visibility days and geographic location factored into the selection," acknowledges the FAA's statement.

An anonymous reader quotes a report from XDA Developers: In January of 2020, Sonos filed two lawsuits against Google, claiming that the latter stole its multiroom speaker technology and infringed on 100 patents. In September, Sonos then sued Google alleging that the company's entire line of Chromecast and Nest products violated five of Sonos' wireless audio patents. A judge (preliminarily) ruled in favor of Sonos. Now it's gone from bad to worse for Google, as the preliminary findings have been finalized by the U.S. International Trade Commission. As a result, Google is not allowed to import any products that violate patents owned by Sonos, which Sonos argues includes Google Pixel phones and computers, Chromecasts, and Google Home/Nest speakers.

These products produced by Google are often made outside of the United States and imported, hence why this is a big deal for Google. In the ruling (PDF) (via The New York Times), Google was also served a cease & desist in order to stop violating Sonos' patents. It has been theorized that as a result of the lawsuit, Google had removed Cast volume controls in Android 12, though it was recently added back with the January 2022 security patch. Sonos has previously said that it had proposed a licensing deal to Google for patents the company was making use of, but that neither company was able to reach an agreement. [...] There are still two more lawsuits pending against Google filed by Sonos, meaning that it's unlikely this is the last we've heard of this spat.

Snap is suing the US Patent and Trademark Office (USPTO) for rejecting its application to trademark the word "spectacles" for its digital eyewear camera device. But the USPTO has maintained that "spectacles" is a generic term for smart glasses and that Snap's version "has not acquired distinctiveness," as required for a trademark. The Verge reports: In its complaint filed Wednesday in US District Court in California, Snap claims that the Spectacles name "evokes an incongruity between an 18th century term for corrective eyewear and Snap's high-tech 21st century smart glasses. SPECTACLES also is suggestive of the camera's purpose, to capture and share unusual, notable, or entertaining scenes (i.e., "spectacles") and while also encouraging users to make 'spectacles' of themselves." Snap first introduced its camera-equipped Spectacles in 2016 ("a wearable digital video camera housed in a pair of fashionable sunglasses," according to its complaint), which can take photos and videos while the user wears them and connects with the Snap smartphone app. [...]

Snap's new complaint posits that there's been enough media coverage of Spectacles, bolstered by some industry awards and its own marketing including social media, to support its claim that consumers associate the word "spectacles" with the Snap brand. Snap first filed a trademark application for Spectacles in September 2016, "for use in connection with wearable computer hardware" and other related uses "among consumer electronics devices and displays." During several rounds of back-and-forth with the company since then, the USPTO has maintained that the word "spectacles" appeared to be "generic in connection with the identified goods," i.e. the camera glasses. Snap continued to appeal the agency's decision. In a November 2021 opinion, the USPTO's Trademark Trial and Appeal Board (pdf) upheld the decision, reiterating that the word "spectacles" was a generic term that applied to all smart glasses, not just Snap's version. Despite the publicity Snap claimed its Spectacles had received from its marketing and social media, the board noted in its opinion that Spectacles' "social media accounts have an underwhelming number of followers, and the number of followers is surprisingly small," which didn't support the company's argument that there had been a high enough level of consumer exposure to Snap's Spectacles to claim that consumers associated the word with Snap's brand.

In its Tuesday complaint, Snap's attorneys argued that "spectacles is an old-fashioned term popular in the 18th century," and that it "is not often used today in the United States," especially by Snapchat's young audience. "This indicates that modern-day usage of "spectacles" in the United States -- especially among a younger demographic of consumers who are the relevant consumers of Snap's SPECTACLES camera product -- is not commonly understood to mean eyeglasses, and certainly not a wireless-enabled video camera product." But the USPTO appeal board said in November that the evidence didn't support that argument, and that the word "spectacles" still retains its generic meaning and therefore can't be trademarked. The board noted that in its own marketing, Snap had demonstrated that its Spectacles "eyeglasses form is a feature, function and characteristic of the camera, not only functionally but aesthetically." Snap's lawsuit, which names acting USPTO director Drew Hirshfeld, seeks to have the appeal board's November decision reversed.

An anonymous reader quotes a report from Ars Technica: The Federal Aviation Administration tentatively agreed not to seek any more 5G delays from AT&T and Verizon, potentially ending a battle over the aviation industry's unproven claim that 5G transmissions on C-Band frequencies will interfere with airplane altimeters. The commitment came Monday night, when AT&T and Verizon agreed to one more delay of two weeks, pushing their deployment off until January 19. They had previously agreed to a delay from December 5 until January 5. Terms of Monday's deal were described in an attachment to a letter (PDF) that Secretary of Transportation Pete Buttigieg sent to the carriers. "In light of the foregoing, and subject to any unforeseen aviation safety issues, DOT and FAA will not seek or demand any further delays of C-Band deployment," the deal terms say.

Buttigieg thanked the AT&T and Verizon CEOs, writing, "Your voluntary agreement both to delay initial deployment by two weeks, and to subsequently adopt some additional mitigations, will give us additional time and space to reduce the impacts to commercial flights... We are confident that your voluntary steps will support the safe coexistence of 5G C-Band deployment and aviation activities." The deal incorporates voluntary commitments that AT&T and Verizon previously made, including "C-Band radio exclusion zones" around airports for six months. The aviation industry will give carriers "a list of no more than 50 priority airports" where the exclusion zones will apply.

AT&T and Verizon will provide data on base stations, operating characteristics, and planned deployment locations. They will also "continue to work in good faith with aviation stakeholders to support the technical assessment of individual altimeters and airport environments," the deal says. The FAA previously said it "will safely expedite the approvals of Alternate Means of Compliance (AMOCs) for operators with high-performing radio altimeters to operate at those airports," signaling that airlines may already be using altimeters that can co-exist with C-Band transmissions. AT&T and Verizon's C-Band spectrum licenses are for the frequencies from 3.7 GHz to 3.98 GHz, but the companies don't plan to deploy between 3.8 GHZ and 3.98 GHz until 2023. The radio altimeters used to determine airplane altitudes rely on spectrum from 4.2 GHz to 4.4 GHz. "Assuming there are no further problems, AT&T and Verizon would be able to use their spectrum licenses without extra restrictions after July 5," the report says.

"At the end of the commitment period specified in the Voluntary Commitments (i.e. through July 5, 2022), Licensees intend to deploy 5G base stations in any manner consistent with their C-Band Licenses, all customary rules and regulations, and any additional airport-specific mitigation measures Licensees have committed to take based on their continued engagement with the FAA and the aviation industry," the agreement said.

"AT&T and Verizon on Sunday rejected the U.S. Department of Transportation's request that they delay this week's scheduled launch of a new round of 5G wireless service," reports Politico, adding that the carriers "instead pledged to take enhanced measures to avoid warned disruptions of air travel..." U.S. Transportation Secretary Pete Buttigieg and FAA Administrator Steve Dickson had asked the companies on New Year's Eve to put off Wednesday's launch of the new wireless service for two additional weeks while their agencies address concerns that the new signals could interfere with some types of aircraft equipment. Unless those issues are resolved, air travelers will face "widespread and unacceptable disruption as airplanes divert to other cities or flights are canceled, causing ripple effects throughout the U.S. air transportation," Buttigieg and Dickson wrote in their letter, reported last week by POLITICO.

The wireless carriers' rebuff is the latest step in weeks of an escalating standoff between the aviation and telecommunication sectors — a year after the mobile phone companies spent more than $80 billion to buy licenses for the 5G-friendly C-band airwaves at a Federal Communications Commission auction. The fight over the Trump-era initiative has drawn in multiple agencies and the White House, with airlines pushing for an emergency stay even after the FCC insisted that the wireless companies can safely use the airwaves...

The FAA on Sunday said it's reviewing the carriers' letter but added, "U.S. aviation safety standards will guide our next actions." Verizon and AT&T told DOT on Sunday that they will embrace even more extensive mitigation measures through July 5. But they outright rejected the idea of postponing the launch of the new 5G service. "Agreeing to your proposal would not only be an unprecedented and unwarranted circumvention of the due process and checks and balances carefully crafted in the structure of our democracy, but an irresponsible abdication of the operating control required to deploy world-class and globally competitive communications networks that are every bit as essential to our country's economic vitality, public safety and national interests as the airline industry," the two companies' CEOs wrote.

They said they want to keep working with the federal government to avoid "escalating" grievances from the airline industry "in other venues."

Reuters reports: U.S. Transportation Secretary Pete Buttigieg and the head of the Federal Aviation Administration (FAA) on Friday asked AT&T and Verizon Communications to delay the planned January 5 introduction of new 5G wireless service over aviation safety concerns. In a letter Friday seen by Reuters, Buttigieg and FAA Administrator Steve Dickson asked AT&T Chief Executive John Stankey and Verizon Chief Executive Hans Vestberg for a delay of no more than two weeks as part of a "proposal as a near-term solution for advancing the co-existence of 5G deployment in the C-Band and safe flight operations."

The aviation industry and FAA have raised concerns about potential interference of 5G with sensitive aircraft electronics like radio altimeters that could disrupt flights.... Earlier Friday the two companies accused the aerospace industry of seeking to hold C-Band spectrum deployment "hostage until the wireless industry agrees to cover the costs of upgrading any obsolete altimeters." Buttigieg and Dickson said under the framework "commercial C-band service would begin as planned in January with certain exceptions around priority airports...." The carriers, which won the spectrum in an $80 billion government auction, previously agreed to precautionary measures for six months to limit interference...

Wireless industry group CTIA said 5G is safe and spectrum is being used in about 40 other countries.

An anonymous reader quotes a report from Ars Technica: Velcro is an ingenious hook-and-loop fastener inspired by nature -- specifically, cockleburs. Now scientists at the Italian Institute of Technology are returning the favor. They have created the first biodegradable Velcro -- inspired by climbing plants -- and used it to build small devices to help monitor the health of crop plants and deliver pesticides and medicines as needed, according to a November paper published in the journal Communications Materials. [...] Co-author Isabella Fiorello and her colleagues were interested in developing innovative new technologies for monitoring plants in situ to detect disease, as well as delivering various substances to plants. However, few such devices can be attached directly to plant leaves without damaging them. The best current options are sensors attached with chemical glues, or with clips. There are also micro-needle-based patches under development able to penetrate leaves for disease detection. Fiorello et al. found inspiration in the common catchweed plant (Galium aparine). It can form dense, tangled mats on the ground, and while the plants can grow up to six feet, they can't stand on their own and instead must use other plants for support. For this purpose, catchweed plants rely on a "unique parasitic ratchet-like anchoring mechanism to climb over host plants, using microscopic hooks for mechanical interlocking to leaves," the authors wrote.

The Italian team closely studied that micro-hook structure and then used a high-resolution 3D printer to create artificial versions, using various materials -- including photosensitive and biodegradable materials made from a sugar-like substance known as isomalt. Their artificial reproductions proved quite capable of attaching to many different plant species, just like their natural counterparts. As an initial application, the team designed a device that could penetrate a plant cuticle with minimal invasiveness, thereby enabling the plant to be monitored and treated, if necessary. The isomalt microhooks attach to the vascular system of leaves and then dissolve inside, because isomalt is soluble. Fiorello et al.'s experiments demonstrated that their artificial micro hooks can be used as a plaster for targeted, controlled release of pesticides, bactericides, or pharmaceuticals onto the leaves. This would greatly reduce the need for broad application of pesticides. And since the plaster dissolves once it's applied, there is no additional waste.

The team also printed hooks made out of a photosensitive resin and assembled them together with sensors for light, temperature, and humidity to make intelligent clips to enable wireless monitoring of the plant's heath. The clips attach to individual leaves, transmitting data wirelessly thanks to customized computer software. The prototype proved resistant to windy conditions and was capable of making real-time measurements for up to 50 days. The devices could be used for small-scale botanical applications, or they could be scaled up. For instance, farmers could distribute many such devices to better map and monitor wide cultivation areas, according to the authors. Finally, Fiorello et al. developed a micro-robotic system capable of moving over the surface of leaves using micro steps, copying the ratchet-like motion of the catchweed plant. Similar actuation mechanisms have previously been demonstrated in Stanford University's SpinyBot -- capable of scaling hard, flat surfaces thanks to arrays of miniature spines on its feet -- and the University of California, Berkeley's CLASH robots, which are capable of climbing up loose suspended cloth surfaces, like curtains.

In the moments before a 6.2-magnitude earthquake struck the northern California coast on Monday, roughly half a million phones began to buzz. From a report: An early-alert system managed by the US Geological Survey sent warnings out before the ground started to shake, giving residents in the sparsely populated area vital time to take cover. The earthquake brought significant shaking but minimal damage in Humboldt county, about 210 miles north-west of San Francisco, and officials said it was an excellent test of the alert-system. It was the largest magnitude quake that's occurred since the system, known as ShakeAlert, was officially rolled out across the west coast. "We got some reports from folks that they got up to 10 seconds' warning before they felt shaking. That's pretty darn good," said Robert de Groot, a ShakeAlert coordinator with the USGS.

ShakeAlert issues warnings through a series of agencies and apps including the MyShakeApp, public wireless emergency alert systems, and the Android operating system, powered by Google. A data package is created from information provided by USGS sensors and -- within seconds -- shows up on phones. Some apps that provide alerts are available to download but even some who didn't have an app on their phone were notified. Affected individuals are instructed to drop, cover, and hold on. Having extra seconds to do so can save lives. This event provided an opportunity for the scientists and system operators to test and improve ShakeAlert so it will be even better when the next big earthquake strikes. "We can run as many simulations and tests as possible but we are really going to learn the most from real earthquakes," de Groot said. "It's giving us the chance to use the system and learn how to do a better job of alerting people."
