An anonymous reader quotes a report from Quartz: Hong Kong's protesters are using AirDrop, a file-sharing feature that allows Apple devices to send photos and videos over Bluetooth and Wi-Fi, to breach China's Great Firewall in order to spread information to mainland Chinese visitors in the city. Leaving AirDrop settings open allows anyone in the vicinity to send files to your device. A protest held yesterday (July 7) in Tsim Sha Tsui, one of Hong Kong's most popular tourist districts, had a clear aim: to tell people from mainland China about the city's opposition to a hated extradition bill, which has mobilized millions of people over the past several weeks to multiple protests and presented the most critical challenge to the local government in decades.

But news of the protest has been heavily censored in mainland China, with any mention of the mass movement wiped off the Chinese internet. Even songs alluding to the city have been scrubbed. As such, many Chinese tourists were visibly confused by the large march, which organizers say drew an estimated 230,000 people. Hong Kong's protesters have therefore turned to Apple's AirDrop feature to get their message across to their mainland Chinese compatriots. That the messages are written in simplified Chinese -- Hong Kongers use traditional Chinese -- confirm that the intended audience is Chinese tourists.

A security researcher has publicly disclosed new vulnerabilities in the USB dongles (receivers) used by Logitech wireless keyboards, mice, and presentation clickers. New submitter raikoseagle shares a report: The vulnerabilities allow attackers to sniff on keyboard traffic, but also inject keystrokes (even into dongles not connected to a wireless keyboard) and take over the computer to which a dongle has been connected. When encryption is used to protect the connection between the dongle and its paired device, the vulnerabilities also allow attackers to recover the encryption key. Furthermore, if the USB dongle uses a "key blacklist" to prevent the paired device from injecting keystrokes, the vulnerabilities allow the bypassing of this security protection system. Marcus Mengs, the researcher who discovered these vulnerabilities, said he notified Logitech about his findings, and the vendor plans to patch some of the reported issues, but not all.

Some think automated radio emails are mucking up the spectrum reserved for amateur radio, while others say these new offerings provide a useful service. Wave723 writes: Like many amateur radio fans his age, Ron Kolarik, 71, still recalls the "pure magic" of his first ham experience nearly 60 years ago. Lately, though, encrypted messages have begun to infiltrate the amateur bands in ways that he says are antithetical to the spirit of this beloved hobby. So Kolarik filed a petition, RM-11831 [PDF], to the U.S. Federal Communications Commission (FCC) proposing a rule change to "Reduce Interference and Add Transparency to Digital Data Communications." And as the proposal makes its way through the FCC's process, it has stirred up heated debate that goes straight to the heart of what ham radio is, and ought to be. The core questions: Should amateur radio -- and its precious spectrum -- be protected purely as a hobby, or is it a utility that delivers data traffic? Or is it both? And who gets to decide?

Since Kolarik filed his petition in late 2018, this debate has engulfed the ham world. Fierce defenders of both sides have filed passionate letters and comments to the FCC arguing their cases. On one side is Kolarik in Nebraska. In his view, it's all rather simple: "Transparency is a core part of ham radio," he says. "And yet, you can find tons of traffic from automatic[ally controlled digital] stations that are extremely difficult to identify, if you can identify them at all, and they cause interference." The automatically controlled digital stations (ACDS) Kolarik refers to can serve to power services like Winlink, a "global radio email" system. Overseen and operated by licensed volunteers around the globe, Winlink is funded and guided by the Amateur Radio Safety Foundation, Inc. (ARSFI). The service uses amateur and government radio frequencies around the globe to send email messages by radio. Users initiate the transmission through an Internet connection, or go Internet-free and use smart-network radio relays.

On Winlink's website, the service says it provides its licensed users the ability to send email with attachments, plus messages about their positions, and weather and information bulletins. Representatives of the service say it also allows users to participate in emergency and disaster relief communications. But Kolarik's petition argues two points: First, because such messages "are not readily and freely able to be decoded," the FCC should require all digital codes to use protocols that "can be monitored in entirety by third parties with freely available, open-source software." Secondly, he wants the rule change to reduce the interference that he says services like Winlink can create between amateur-to-amateur stations -- by relegating the often-unattended automatic stations to operate solely on narrower sub-bands. Loring Kutchins, the president of ARSFI, says he believes Kolarik's petition is "well intentioned in its basis. But the fundamental conflict is between people who believe amateur radio is about hobby, not about utility. But nowhere do the FCC rules use the word 'hobby.'"

Google's bet on balloons to deliver cell service soon faces a crucial test amid doubts about the viability of the technology by some potential customers. From a report: The company behind the effort, Loon says its balloons will reach Kenya in the coming weeks for its first commercial trial. The test with Telkom Kenya, the nation's No. 3 carrier, will let mountain villagers buy 4G service at market-rate prices for an undefined period. Kenya's aviation authority said its final approval would be signed this month. Hatched in 2011, Loon aims to bring connectivity to remote parts of the world by floating solar-powered networking gear over areas where cell towers would be too expensive to build.

Its tennis-court-sized helium balloons have demonstrated utility. Over the last three years, Loon successfully let wireless carriers in Peru and Puerto Rico use balloons for free to supplant cell phone towers downed by natural disasters. Kenyan officials are enthusiastic as they try to bring more citizens online. But executives at five other wireless carriers courted by Loon across four continents told Reuters that Loon is not a fit currently, and may never be. Those companies, including Telkom Indonesia, Vodafone New Zealand and French giant Orange, say Loon must demonstrate its technology is reliable, safe and profitable for carriers.

Ever since Frontier bought Verizon's Texas network in 2016, the company has been charging some customers a $10-per-month router rental fee even if they're using their own router. Rich Son of Texas purchased Verizon's FiOS Quantum Gateway router for $200 in order to avoid monthly rental fees. He said: "[the router] worked well for me until the takeover happened with Frontier and I began getting charged for using my own equipment. I have continued to call Frontier and was repeatedly assured that the fees will be taken off my bill." But that didn't happen. Ars Technica reports: Son filed a complaint with the Federal Communications Commission; Frontier responded to the complaint but stuck to its position that he has to pay the fee. A voicemail that Frontier left with Son and his wife said the company informed the FCC that "the router monthly charge is an applicable fee, and it will continue to be billed." Another voicemail from Frontier told them they can avoid the monthly rental fees if they purchase a Frontier router.

"We can reimburse you if you purchase a Frontier router. We cannot reimburse you if you have a Verizon router -- we are not Verizon," the voicemail said. "You can choose to use your own router, however you will be still charged the monthly fee... the difference is we do not service the router that you choose to use." "It's $10 today -- but how much will it cost us tomorrow?" Son said. "I'd consider letting it go if their customer service blew me out of the water, but they've been terrible ever since Verizon forced Frontier on us." When contacted by Ars Technica, Frontier said that it refuses to stop charging the Wi-Fi router rental fee even when customers use their own router and claimed it does so in order to cover higher support costs for customers like Son."

In what looks set to become one of the highest profile patent sales in years, Intel has put its IP relating to cellular wireless connectivity on the auction block. The company is seeking to divest around 8,500 assets from its massive portfolio. From a report: The news comes as the chip giant searches for a buyer for its 5G smartphone modem business having announced in April that it was pulling out of the market. That was after as it had become increasingly clear that the company, which has been the supplier of 4G modem chips to Apple for the last few years, was struggling to release a 5G product even though the rollout of the next generation of mobile technology is well underway. The auction offering is comprised of two parts: the cellular portfolio and a connected device portfolio. The former includes approximately 6,000 patent assets related to 3G, 4G and 5G cellular standards and an additional 1,700 assets that read on wireless implementation technologies. The latter is made up of 500 patents with broad applicability across the semiconductor and electronics industries. Although that represents a large portion of Intel's cellular IP it is understood that it will retain significant wireless assets.

An anonymous reader quotes a report from Motherboard: A community-run operation named NYC Mesh is on a mission: to deliver better, cheaper broadband service to New York City. The locally-run nonprofit project says it's engaging in a dramatic expansion that should soon deliver a new, more open broadband alternative to big ISPs to a wider swath of the boroughs of Manhattan and Brooklyn. With the installation of a new "supernode," NYC Mesh has greatly expanded its coverage area to much of western Brooklyn, as well as much of lower Manhattan.

Born out of frustration in 2013, NYC Mesh isn't a traditional business. It's built on the backs of volunteers and donors who dedicate their time, money, bandwidth, hardware, and resources to building an alternative to the abysmal logjam that is shoddy US broadband. Initially, the mesh network was powered by a single "Supernode" antenna and hardware array located at 375 Pearl Street in Manhattan. This gigabit fiber-fed antenna connects 300 buildings, where members have mounted routers on a rooftop or near a window. These local "nodes" in turn connect to an internet exchange point -- without the need for a traditional ISP. Unlike a traditional ISP, users don't pay a fixed monthly rate, and there are no costly monthly usage caps or overage fees. A NYC Mesh rate sheet notes the project is funded by optional monthly member donations of $20 or $50 for a residential users, or $100 for a business. Users also pay $110.00 for a WiFi router and rooftop antenna, and a $50 installation fee. The organization announced that it will install a new Supernode 3 antenna and hardware array at Industry City in the Sunset Park neighborhood of Brooklyn. "According to NYC Mesh, this new supernode will have 50 times the capacity of the original node, allowing the project to extend availability to Sunset Park, South Slope, Park Slope, Gowanus, Red Hook, and beyond," reports Motherboard.

Ericsson announced its plans to build a 5G factory in the U.S. sometime early next year. "The factory will be the Swedish telco equipment maker's first fully-automated factory, the company said, and will be used to produce 5G radios designed for urban areas," reports ZDNet. "It will also make Advanced Antenna System radios that it said are components for large-scale deployments of 4G and 5G networks for both rural and urban coverage." From the report: Ericsson did not provide details about where the factory will be located, but the company has plans to initially employ around 100 people at the factory, which will have "highly automated operations." Ericsson is currently signed on by T-Mobile, Verizon, Sprint, AT&T, US Cellular, and GCI to help build out their respective 5G mobile networks. According to the Ericsson's latest mobility report, North America is expected to lead in the adoption of 5G, with the company predicting that 63% of North American mobile subscriptions will be 5G-based in 2024. Fierce Wireless says the company has made a direct investment of about $100 million, "which will kick in during the third quarter of this year."

After an emergency alert was accidentally sent to Hawaii residents last year, warning of an impending nuclear ballistic missile attack, researchers at the University of Colorado Boulder were prompted to ask the question: How easy would it be to exploit the nation's emergency alert systems, wreaking havoc on the American public via fake or misleading alerts? In short, they found that it wasn't very difficult at all. Motherboard reports: Their full study was recently unveiled at the 2019 International Conference on Mobile Systems, Applications and Services (MobiSys) in Seoul, South Korea. It documents how spoofing the Wireless Emergency Alert (WEA) program to trick cellular users wasn't all that difficult. To prove it, researchers built a mini "pirate" cell tower using easily-available hardware and open source software. Using isolated RF shield boxes to mitigate any real-world harm, they then simulated attacks in the 50,000 seat Folsom Field at the University. 90 percent of the time, the researchers say they were able to pass bogus alerts on to cell phones within range. The transmission of these messages from the government to the cellular tower is secure. It's the transmission from the cellular tower to the end user that's open to manipulation and interference, the researchers found. The vulnerability potentially impacts not just US LTE networks, but LTE networks from Europe to South Korea.

The Trump administration is examining whether to require that next-generation 5G cellular equipment used in the U.S. be designed and manufactured outside China [Editor's note: the link may be paywalled; alternative source], WSJ reports, citing people familiar with the matter. The move could reshape global manufacturing and further fan tensions between the countries. From the report: A White House executive order last month to restrict some foreign-made networking gear and services due to cybersecurity concerns started a 150-day review of the U.S. telecommunications supply chain. As part of that review, U.S. officials are asking telecom-equipment manufacturers whether they can make and develop U.S.-bound hardware, which includes cellular-tower electronics as well as routers and switches, and software outside of China, the people said. The conversations are in early and informal stages, they said. The executive order calls for a list of proposed rules and regulations by the 150-day deadline, in October; so, any proposals may take months or years to adopt.

The proposals could force the biggest companies that sell equipment to U.S. wireless carriers, Finland's Nokia and Sweden's Ericsson, to move major operations out of China to service the U.S., which is the biggest market in the $250 billion-a-year global industry for telecom equipment and related services and infrastructure. There is no major U.S. manufacturer of cellular equipment. U.S. officials have long worried that Beijing could order Chinese engineers to insert security holes into technology made in China. They worry those security holes could be exploited for spying, or to remotely control or disable devices.

Raspberry Pi today introduced a new version of its popular line of single-board computer. The Raspberry Pi 4 Model B is the fastest Raspberry Pi ever, with the company promising "desktop performance comparable to entry-level x86 PC systems." The specifications are: A 1.5GHz quad-core 64-bit ARM Cortex-A72 CPU (~3x performance); 1GB, 2GB, or 4GB of LPDDR4 SDRAM; full-throughput Gigabit; Ethernet; dual-band 802.11ac wireless networking; Bluetooth 5.0; two USB 3.0 and two USB 2.0 ports; dual monitor support, at resolutions up to 4K; VideoCore VI graphics, supporting OpenGL ES 3.x; 4Kp60 hardware decode of HEVC video; and complete compatibility with earlier Raspberry Pi products. It starts at $35.

Fake presidential alerts could be sent to tens of thousands of phones, according to a report out of the University of Colorado Boulder. From a report: Researchers say they found a backdoor that let them mimic alerts and blast fake messages to people confined to a small area, such as a city block or a sports stadium. The researchers developed software mimicking the presidential alert format and then used commercially available wireless transmitters to send the messages to phones within their radius. The team had a success rate of hitting 90% of all phones in the area it tested.

A new comprehensive study on Global Positioning System technology has examined what effect a 30-day outage would have on the U.S. economy -- whether it's due to a severe space weather event or "nefarious activity by a bad actor." If a widespread outage were to occur, the study estimates it would have a $1 billion per-day impact. "It would likely be higher during the planting season of April and May, when farmers are highly reliant on GPS technology for information about their fields," adds Ars Technica. From the report: To assess the effect of an outage, the study looked at several different variables. Among them was "precision timing" that enables a number of wireless services, including the synchronization of traffic between carrier networks, wireless handoff between base stations, and billing management. Moreover, higher levels of precision timing enable higher bandwidth and provide access to more devices. (For example, the implementation of 4G LTE technology would have been impossible without GPS technology). In the case of an outage, there would be relatively minimal impacts over the first two days, but after that time, the wireless network would begin to degrade significantly. After 30 days, the study estimates that functionality would lie somewhere between 0 percent and 60 percent of normal operating levels. Landline phones would be largely unaffected.

In an opinion piece for The New York Times, writer Michael Kwet sheds some lights on the secret bluetooth surveillance devices retailers use to track your every move and better serve ads to you. Anonymous reader shares an excerpt from the report: Imagine you are shopping in your favorite grocery store. As you approach the dairy aisle, you are sent a push notification in your phone: "10 percent off your favorite yogurt! Click here to redeem your coupon." You considered buying yogurt on your last trip to the store, but you decided against it. How did your phone know? Your smartphone was tracking you. The grocery store got your location data and paid a shadowy group of marketers to use that information to target you with ads. Recent reports have noted how companies use data gathered from cell towers, ambient Wi-Fi, and GPS. But the location data industry has a much more precise, and unobtrusive, tool: Bluetooth beacons. These beacons are small, inobtrusive electronic devices that are hidden throughout the grocery store; an app on your phone that communicates with them informed the company not only that you had entered the building, but that you had lingered for two minutes in front of the low-fat Chobanis.

Most location services use cell towers and GPS, but these technologies have limitations. Cell towers have wide coverage, but low location accuracy: An advertiser can think you are in Walgreens, but you're actually in McDonald's next door. GPS, by contrast, can be accurate to a radius of around five meters (16 feet), but it does not work well indoors. Bluetooth beacons, however, can track your location accurately from a range of inches to about 50 meters. They use little energy, and they work well indoors. That has made them popular among companies that want precise tracking inside a store. In order to track you or trigger an action like a coupon or message to your phone, companies need you to install an app on your phone that will recognize the beacon in the store. Retailers (like Target and Walmart) that use Bluetooth beacons typically build tracking into their own apps. But retailers want to make sure most of their customers can be tracked -- not just the ones that download their own particular app.

In retail stores, Bluetooth "beacons" are watching you, using hidden technology in your phone. From a report: Imagine you are shopping in your favorite grocery store.

An anonymous reader quotes a report from Reuters: Ten states led by New York and California filed a lawsuit on Tuesday to stop T-Mobile's $26 billion purchase of Sprint, warning that consumer prices will jump due to reduced competition. The complaint comes as the U.S. Justice Department is close to making a final decision on the merger, which would reduce the number of nationwide wireless carriers to three from four. The all-Democratic attorneys general from the 10 states, including Colorado, Connecticut, the District of Columbia, Maryland, Michigan, Mississippi, Virginia and Wisconsin, say the reduced competition would cost Sprint and T-Mobile subscribers more than $4.5 billion annually, according to the complaint. If the states' lawsuit goes forward, the courts would have the last say, not the Justice Department, Blair Levin, an analyst with New Street Research, said in a note on Tuesday. The next two big steps will be determining the position of Makan Delrahim, head of the Justice Department's antitrust division, and the identity of the judge assigned to the states' lawsuit, Levin wrote.

In a new essay Friday, technology pundit Robert Cringely remembers the day he got his first home fax machine in 1986, arguing that broadcast television is like a fax machine -- in that "they are both obsolete."

Then he offers a quick history of television, cable TV, and the rise of Netflix, concluding "I'll be surprised if broadcast TV in the U.S. survives another decade" -- also predicting the end of cable TV packages: 5G wireless networking, as I've written here before, has pretty much nothing to do with mobile phones. It has to do with replacing every other kind of data network with 5G wireless. No more land lines, no more cable systems, no more wires. Going all-wireless almost completely eliminates customer-facing labor. No more guy with a tool belt to keep you waiting for service. No more truck rolls. There will be 5G and there will be content, that's all.

Content can mean a phone call or a movie, a game, or anything else that involves electrons in motion. And given that we'll all have voracious and completely different demands for high-resolution content, 5G will suck-up all available bandwidth and then some. Legacy broadcast license holders like broadcast TV and radio stations will sell their airspace to 5G carriers and retire to Florida. They'll get offers they can't refuse....

Cable TV packages will fall apart with every network fighting for itself in an a la carte programming world.
"There's nothing sacrosanct about a broadcast network paradigm that we've been riding for a century," he concludes. "This too shall pass."

Bitcoin has a lingering problem that few people are talking about amid the renewed exuberance of the recent price surge. From a report: Hardly anyone is using the world's largest cryptocurrency for anything beyond speculation. Data from New York-based blockchain researcher Chainalysis show that only 1.3% of economic transactions came from merchants in the first four months of 2019, little changed over the boom and bust cycles of the prior two years. Even though marque companies such as AT&T now let customers pay with cryptocurrencies, the problem is that few speculators want to use the digital coins to pay for wireless services when the digital asset's price might surge another 50% in a matter of weeks. That's become the main dilemma with the cryptocurrency: Bitcoin needs the hype to attract mass appeal to be considered a viable electronic alternative to money but it has developed a culture of "hodlers" who advocate accumulation rather than spending.

samleecole writes: Apple's AirPods are a tragedy. Ecologically, socially, economically -- they're a capitalist disaster. The opposite of AirPods, then, is this extremely punk pair of DIY wireless earbuds that someone on Reddit hacked together using an old pair of wired Apple headphones and some hot glue. "I started this project roughly two months ago when my friend got a new pair of AirPods for his birthday and I thought to myself, 'that's quite a lot of money for something I can make at home,'" Sam Cashbook, who is 15, told Motherboard in a Reddit message.

Cashook started watching videos of people making their own AirPods, but mostly found people chopping the wires off of Apple headphones as a joke. He decided to take his own approach. He bought a hands-free bone conduction headset from eBay, and took apart the casing to reveal the electronics. Then, he desoldered the wires from the original speaker in the headset, and connected his old Apple earbud speaker to the headset's printed circuit board. Maybe a little uglier, but the headphones work well, he said. The set has buttons for power, pausing music, volume controls and skipping tracks, and the battery is rechargeable.

Amazon is reportedly interested in buying prepaid cellphone wireless service Boost Mobile from U.S. carriers T-Mobile and Sprint. "Amazon is considering buying Boost mainly for an attached wholesale deal that would allow the buyer to use T-Mobile's wireless network for at least six years," reports Reuters, citing two sources familiar with the matter. "Amazon would also be interested in any wireless spectrum that could be divested." From the report: It was not immediately clear why the U.S. online retail giant and cloud services provider would want the wireless network and spectrum. T-Mobile and Sprint have offered concessions, including selling Boost, to reduce their market share in the prepaid wireless business and gain regulatory approval for their planned $26 billion merger. The U.S. Justice Department would need to scrutinize the buyer of a divested asset to ensure it will stay viable and preserve competition. The carriers are also considering divesting wireless spectrum, or airwaves that carry data, in order to push the merger through.
