U.S. officials issued an advisory warning that foreign-made solar-powered highway infrastructure may contain hidden radios embedded in inverters and batteries. Reuters reports: The advisory, disseminated late last month by the U.S. Department of Transportation's Federal Highway Administration, comes amid escalating government action over the presence of Chinese technology in America's transportation infrastructure. The four-page security note, a copy of which was reviewed by Reuters, said that undocumented cellular radios had been discovered "in certain foreign-manufactured power inverters and BMS," referring to battery management systems.

The note, which has not previously been reported, did not specify where the products containing undocumented equipment had been imported from, but many inverters are made in China. There is increasing concern from U.S. officials that the devices, along with the electronic systems that manage rechargeable batteries, could be seeded with rogue communications components that would allow them to be remotely tampered with on Beijing's orders. [...]

The August 20 advisory said the devices were used to power a range of U.S. highway infrastructure, including signs, traffic cameras, weather stations, solar-powered visitor areas and warehouses, and electric vehicle chargers. The risks it cited included simultaneous outages and surreptitious theft of data. The alert suggested that relevant authorities inventory inverters across the U.S. highway system, scan devices with spectrum analysis technology to detect any unexpected communications, disable or remove any undocumented radios, and make sure their networks were properly segmented.

Philips Hue is rolling out MotionAware, a new feature that turns its smart bulbs into motion sensors using radio-frequency (RF) Zigbee signals. The upgrade works with most Hue bulbs made since 2014, but requires the new $99 Bridge Pro hub to enable. The Verge reports: To create a MotionAware motion-sensing zone, you need Hue's new Bridge Pro and at least three Hue devices in a room. It works with all new and most existing mains-powered Hue products via a firmware update. That includes smart bulbs, light strips, and fixtures. Portable devices, such as the Hue Go or Table Lamp, and battery-powered accessories, such as Hue switches, aren't compatible. Neither is Hue's current smart plug. [...] "All of the functionality you get with our physical motion sensors -- including turning on when motion is detected or off when there's been no movement for a certain amount of time -- can be configured on motion-aware motion events," says George Yianni, Hue CTO and founder, in an interview with The Verge. "We've done something that's quite a lot better than what else is out there."

MotionAware is occupancy sensing, not presence sensing; it requires movement. Yianni says it's comparable to the passive infrared sensing (PIR) Hue's physical sensors use. This means it can be triggered by pets or other motion. A sensitivity slider in the app helps fine-tune detection. According to Yianni, a key benefit over PIR is that a MotionAware zone can cover a larger area than a single PIR sensor, and it's also not limited to line of sight. MotionAware can't sense light levels, which Hue Motion Sensors can, but you can pair a light sensor to a motion zone to feed it that data. The positioning of the lights will also play a role in determining the effectiveness of the motion sensing. "We recommend that the lights surround an area which will roughly define the detection area in which motion will be detected," says Yianni. "It will sense around the lights and in the broader room thanks to reflections, but detection reliability will depend on lots of factors."

Beyond lighting automation, MotionAware can also integrate with Hue Secure, Hue's DIY security platform that includes cameras, contact sensors, and a new video doorbell. Motion detection can trigger lights to flash red, activate Hue's new plug-in chime/siren, and send an alert to your phone with a button to call emergency services. [...] MotionAware is built on RF sensing -- a technology that uses wireless signals to "see" a space and detect disruptions within it. The data is then sent to the Bridge Pro, where AI algorithms are applied to figure out what is causing those disruptions, so the system can act accordingly. This is why it's limited to the Bridge Pro, the V2 bridge isn't powerful enough to run those algorithms, says Yianni.

An anonymous reader quotes a report from Wired: Two years ago, researchers in the Netherlands discovered an intentional backdoor in an encryption algorithm baked into radios used by critical infrastructure -- as well as police, intelligence agencies, and military forces around the world -- that made any communication secured with the algorithm vulnerable to eavesdropping. When the researchers publicly disclosed the issue in 2023, the European Telecommunications Standards Institute (ETSI), which developed the algorithm, advised anyone using it for sensitive communication to deploy an end-to-end encryption solution on top of the flawed algorithm to bolster the security of their communications. But now the same researchers have found that at least one implementation of the end-to-end encryption solution endorsed by ETSI has a similar issue that makes it equally vulnerable to eavesdropping. The encryption algorithm used for the device they examined starts with a 128-bit key, but this gets compressed to 56 bits before it encrypts traffic, making it easier to crack. It's not clear who is using this implementation of the end-to-end encryption algorithm, nor if anyone using devices with the end-to-end encryption is aware of the security vulnerability in them. Wired notes that the end-to-end encryption the researchers examined is most commonly used by law enforcement and national security teams. "But ETSI's endorsement of the algorithm two years ago to mitigate flaws found in its lower-level encryption algorithm suggests it may be used more widely now than at the time."

alternative_right shares a report from Phys.Org: A cosmic particle detector in Antarctica has emitted a series of bizarre signals that defy the current understanding of particle physics, according to an international research group that includes scientists from Penn State. The unusual radio pulses were detected by the Antarctic Impulsive Transient Antenna (ANITA) experiment, a range of instruments flown on balloons high above Antarctica that are designed to detect radio waves from cosmic rays hitting the atmosphere.

The goal of the experiment is to gain insight into distant cosmic events by analyzing signals that reach the Earth. Rather than reflecting off the ice, the signals -- a form of radio waves -- appeared to be coming from below the horizon, an orientation that cannot be explained by the current understanding of particle physics and may hint at new types of particles or interactions previously unknown to science, the team said. The researchers published their results in the journal Physical Review Letters.

"The radio waves that we detected were at really steep angles, like 30 degrees below the surface of the ice," said Stephanie Wissel, associate professor of physics, astronomy and astrophysics who worked on the ANITA team searching for signals from elusive particles called neutrinos. She explained that by their calculations, the anomalous signal had to pass through and interact with thousands of kilometers of rock before reaching the detector, which should have left the radio signal undetectable because it would have been absorbed into the rock. "It's an interesting problem because we still don't actually have an explanation for what those anomalies are, but what we do know is that they're most likely not representing neutrinos," Wissel said.

alternative_right shares a report: New York state lawmakers voted to stop the NYPD's attempt to block its radio communications from the public Thursday, with the bill expected to head to Gov. Kathy Hochul's desk. The "Keep Police Radio Public Act" passed both the state Senate and state Assembly, with a sponsor of the legislation arguing the proposal strikes the "proper balance" in the battle between transparency and sensitive information.

"Preserving access to police radio is critical for a free press and to preserve the freedoms and protections afforded by the public availability of this information," state Sen. Michael Gianaris (D-Queens) said in a statement. "As encrypted radio usage grows, my proposal strikes the proper balance between legitimate law enforcement needs and the rights and interests of New Yorkers."

The bill, which was sponsored in the Assembly by lawmaker Karines Reyes (D-Bronx), is meant to make real-time police radio communications accessible to emergency services organizations and reporters. "Sensitive information" would still be kept private, according to the legislation. In late 2023, the NYPD began encrypting its radio communications to increase officer safety and "protect the privacy interests of victims and witnesses." However, it led to outcry from press advocates and local officials concerned about reduced transparency and limited access to real-time information.

A bill to address the issue has passed both chambers of New York's legislature, but Governor Hochul has not yet indicated whether she will sign it.

An anonymous reader quotes a report from Ars Technica: Federal Communications Commission Chairman Brendan Carr has threatened to revoke EchoStar licenses for radio frequency bands coveted by rival firms including SpaceX, which alleges that EchoStar is underutilizing the spectrum. "I have directed agency staff to begin a review of EchoStar's compliance with its federal obligations to provide 5G service throughout the United States per the terms of its federal spectrum licenses," Carr wrote in a May 9 letter to EchoStar Chairman Charles Ergen. EchoStar and its affiliates "hold a large number of FCC spectrum licenses that cover a significant amount of spectrum," the letter said.

Ergen defended his company's wireless deployment but informed investors that EchoStar "cannot predict with any degree of certainty the outcome" of the FCC proceedings. The letter from Carr and Ergen's statement is included in a Securities and Exchange Commission filing submitted by EchoStar today. EchoStar's stock price was down about 8 percent in trading today. EchoStar bought Dish Network in December 2023 and offers wireless service under the Boost Mobile brand. As The Wall Street Journal notes, the firm "has spent years wiring thousands of cellphone towers to help Boost become a wireless operator that could rival AT&T, Verizon and T-Mobile, but the project has been slow-going. Boost's subscriber base has shrunk in the five years since Ergen bought the brand from Sprint." [...]

EchoStar will have to prove its case in the two FCC proceedings. The FCC set a May 27 deadline for the first round of comments in both proceedings and a June 6 deadline for reply comments. The proceedings could result in the FCC letting other companies use the spectrum and other remedies. "In particular, we seek information on whether EchoStar is utilizing the 2 GHz band for MSS consistent with the terms of its authorizations and the Commission's rules and policies governing the expectation of robust MSS," the FCC Space Bureau's call for comments said. "We also seek comment on steps the Commission might take to make more intensive use of the 2 GHz band, including but not limited to allowing new MSS entrants in the band." Last month, SpaceX urged the FCC to reallocate the spectrum, saying "the 2 GHz band remains ripe for sharing among next-generation satellite systems that seek to finally make productive use of the spectrum for consumers and first responders."

EchoStar countered that SpaceX's filing is "intended to cloak another land grab for even more free spectrum," and that its "methodology is completely nonsensical, given that EchoStar's terrestrial deployment is subject to population-based milestones that EchoStar has repeatedly demonstrated in status reports."

The Sydney-based CADA station secretly used an AI-generated host named "Thy" for its weekday shows over six months without disclosure. The Sydney Morning Herald reports: After initial questioning from Stephanie Coombes in The Carpet newsletter, it was revealed that the station used ElevenLabs -- a generative AI audio platform that transforms text into speech -- to create Thy, whose likeness and voice were cloned from a real employee in the ARN finance team. The Australian Communications and Media Authority said there were currently no specific restrictions on the use of AI in broadcast content, and no obligation to disclose its use.

An ARN spokesperson said the company was exploring how new technology could enhance the listener experience. "We've been trialling AI audio tools on CADA, using the voice of Thy, an ARN team member. This is a space being explored by broadcasters globally, and the trial has offered valuable insights." However, it has also "reinforced the power of real personalities in driving compelling content," the spokesperson added.

The Australian Financial Review reported that Workdays with Thy has been broadcast on CADA since November, and was reported to have reached at least 72,000 people in last month's ratings. Vice president of the Australian Association of Voice Actors, Teresa Lim, said CADA's failure to disclose its use of AI reinforces how necessary legislation around AI labelling has become. "AI can be such a powerful and positive tool in broadcasting if there are correct safeguards in place," she said. "Authenticity and truth are so important for broadcast media. The public deserves to know what the source is of what's being broadcast ... We need to have these discussions now before AI becomes so advanced that it's too difficult to regulate."

New submitter grandrollerz writes: Despite streaming online since the RealAudio days of the late 1990s, the BBC has announced that most of its radio stations will become unavailable to international users later this year. Starting in Spring 2025, only talk news stations BBC World Service and BBC Radio 4 will remain accessible outside the UK. This change is due to rights issues and the launch of a new BBC audio website and app that will replace BBC Sounds for international users. The BBC Sounds app will be available exclusively to UK audiences, although UK users traveling abroad for short periods will still be able to use it. This move has disappointed many long-time international listeners who will lose access to their favorite BBC radio stations. It follows a similar move to further commercialize its services where in 2024 the BBC and Amazon Music struck a global deal to make BBC podcasts available on Amazon Music outside the UK, but only for subscribers to Amazon's Prime and Amazon Music Unlimited services.

A bipartisan group of legislators has reintroduced the AM Radio for Every Vehicle Act of 2025, aiming to mandate AM radio in all new vehicles at no additional cost. Adweek reports: The AM Radio for Every Vehicle Act was first introduced in May 2023. It continued to take on new co-sponsors through the fall of 2024. It was reintroduced as the AM Radio for Every Vehicle Act of 2025 with 62 cosponsors. Upper Midwest senators showing support for the bill include Sens. John Hoeven and Kevin Cramer R-North Dakota, and Sens. Amy Klobuchar and Tina Smith, DFL- Minnesota.

If enacted, the bill would require the Department of Transportation to issue a rule requiring new vehicles to maintain access to broadcast AM radio at no additional cost to the consumer and provide small vehicle manufacturers at least four years after the date DOT issues the rule to comply. The act also requires automakers to inform consumers, during the period before the rule takes effect, that the vehicles do not maintain access to broadcast AM radio. "With 82 million Americans tuning in each month, AM radio delivers more than just emergency alerts," says the National Association of Broadcasters in a news release. "It connects communities through hyper-local content, including news, weather and diverse cultural programming," according to a news release from the National Association of Broadcasters."

Cornell Tech researchers have developed a portable device called SoilScanner that uses radio frequency signals and machine learning to detect lead contamination in soil. It offers a cost-effective alternative to traditional methods of testing that "generally involves either sending samples to a lab for analysis, which relies upon harsh chemicals and can be expensive, or using a portable X-ray fluorescence device," notes Phys.org. From the report: "In recent years, especially during COVID, a lot of us got excited about having our own backyard garden, or spending more time at home," said [Rajalakshmi Nandakumar, assistant professor at the Jacobs Technion-Cornell Institute at Cornell Tech] who's also a member of the Department of Information Science in the Cornell Ann S. Bowers College of Computing and Information Science. "But if you look at instructions for how to grow tomatoes, no one actually tells you that you have to check your soil for lead," she said. "It's all about pH levels. A lot of us, even though we interact very often with soils, are totally unaware of possible lead contamination."

[Yixuan Gao, a doctoral candidate in computer science] said the group was motivated by a map of lead contamination in New York City that Cheng's Urban Soils Lab (USL) had produced over the course of several years of testing for hundreds of soil samples throughout the five boroughs. The testing revealed dangerously high levels of lead in many locations, most notably in northern Brooklyn. About 45% of the soil samples tested by USL had lead levels above 400 parts per million (ppm), the previous EPA recommended screening level (revised a year ago to 200 ppm for residential soils). "This means there is a significant risk when gardening in these urban soils," Gao said. You can learn more about the device here (PDF).

Starlink has launched home Internet service to 99.5% of residents in the National Radio Quiet Zone (NRQZ) after a multi-year collaboration with the National Radio Astronomy Observatory to minimize interference with radio telescopes. "The vast majority of people within the areas of Virginia and West Virginia collectively known as the National Radio Quiet Zone (NRQZ) can now receive high speed satellite Internet service," the National Radio Astronomy Observatory and Green Bank Observatory announced said. "The newly available service is the result of a nearly three-year collaborative engineering effort between the US National Science Foundation (NSF), SpaceX, and the NSF National Radio Astronomy Observatory (NSF NRAO), which operates the NSF Green Bank Observatory (NSF GBO) in West Virginia within the NRQZ." Ars Technica reports: There's a controversy over the 0.5 percent of residents who aren't included and are said to be newly blocked from using the Starlink Roam service. Starlink markets Roam as a service for people to use while traveling, not as a fixed home Internet service. The Pendleton County Office of Emergency Management last week issued a press release (PDF) saying that "customers with the RV/Roam packages had been using Starlink for approximately two years throughout 100% of the NRQZ. Now, the 0.5% have lost coverage after having it for two years. This means that a large section of southeastern Pendleton County and an even larger section of northern Pocahontas will NOT be able to utilize Starlink."

PCMag wrote that "Starlink is now live in 42 of the 46 cell areas around the Green Bank Observatory's telescopes." Pendleton County Emergency Services Coordinator Rick Gillespie told Ars today that Roam coverage was cut off in the remaining four cell areas. "After the agreement, we all lost effective use within the four cells," Gillespie told Ars in an email. Gillespie's press release said that, "in many cases, Starlink was the only Internet provider option residents and emergency responders had. This is unacceptable."

OFF Radio Krakow sparked controversy by replacing its journalists with AI-generated presenters in an experiment to attract younger audiences. CNN Business reports: Weeks after letting its journalists go, OFF Radio Krakow relaunched this week, with what it said was âoethe first experiment in Poland in which journalists ... are virtual characters created by AI." The station in the southern city of Krakow said its three avatars are designed to reach younger listeners by speaking about cultural, art and social issues including the concerns of LGBTQ+ people. "Is artificial intelligence more of an opportunity or a threat to media, radio and journalism? We will seek answers to this question," the station head, Marcin Pulit, wrote in a statement.

The House Energy and Commerce Committee has approved the AM for Every Vehicle Act, which mandates that automakers include AM radio in new vehicles without additional charges. The Verge reports: The bill passed the committee on a roll-call vote of 45-2 and now heads to the full House for final approval. The bill, titled the AM for Every Vehicle Act, would direct the National Highway Traffic Safety Administration (NHTSA) to issue a rule that "requires automakers to maintain AM broadcast radio in their vehicles without a separate or additional payment, fee, or surcharge." Supporters say they are pushing the bill out of a concern that the slow demise of AM radio could make it more difficult to broadcast emergency information during a natural disaster or other related events. Conservatives are also worried about losing a lucrative platform for right-wing news and media. [...]

Automakers generally see AM radio as an obsolete technology, arguing that there are other, better technologies, such as internet streaming, HD radio delivered on FM bands, or some apps that provide AM content that will make up for the absence of AM radio in vehicles. Critics say the bill could also add to the costs of producing EVs at a time when many manufacturers are struggling to rein in their costs. "With a new mandate, [EV companies] will have to go through a significant powertrain redesign, vehicle redesign," Albert Gore, executive director of the Zero Emission Transportation Association, said in an interview earlier this year, "because of the degree to which electric motor generates this [electromagnetic] interference."

Digital audio broadcasting (DAB+) and internet radio have largely replaced traditional FM radio in Switzerland, with digital radio holding an 81% share of use in spring 2023. Due to the high costs of maintaining FM transmitters and declining financial resources, Switzerland plans to fully transition to digital radio by the end of 2026, phasing out FM broadcasting completely. From a report: DAB+ and the internet offer better quality and a larger program selection, are more energy and cost efficient, and can provide additional information in text and images, it said. To receive DAB+ requires a corresponding device or adapter, and new cars have been equipped with digital technology as standard for several years. In addition, the Federal Roads Office (FEDRO) will upgrade all tunnels on the national road network for digital radio reception by the end of the year and switch off FM transmitters.

FM was originally expected to be switched off throughout Switzerland by the end of 2024. The government extended FM licenses for the radio industry for the last time in October 2023 to the end of 2026, after which radio stations in Switzerland will no longer be able to broadcast via FM, only digitally. OFCOM announced at the time that the final extension would give the radio industry the flexibility to complete the transition process from analogue to digital radio.

Apple has quietly added a Thread radio to nearly all of its newest iPads, MacBooks, and iMacs. The Verge reports: While the company doesn't list Thread on the specs of any of these products, FCC reports indicate that many of Apple's latest devices have had Thread radios tested for compliance. Generally, you don't test a radio that's not there. We found evidence of Thread testing in the following models: iPad Pro 13-inch (M4) (Wi-Fi + Cellular), iPad Pro 11-inch (M4) (Wi-Fi + Cellular), iPad Pro 11-inch (M4) (Wi-Fi), iPad Air 11-inch (M2) (Wi-Fi + Cellular), iPad Air 13-inch (M2) Wi-Fi, MacBook Air 15-inch (M3), MacBook Pro 14-inch (M3), MacBook Pro 14-inch (M3 Pro or M3 Max), MacBook Pro 16-inch (M3 Pro or M3 Max), iMac (M3, two ports), and iMac (M3, four ports).

The FCC requires manufacturers to list every radio contained in a device and to test them in every possible scenario to make sure they comply with its transmission regulations. Tom Sciorilli, director of certification for Thread Group, told The Verge that the FCC reports reference FCC 15.247, "which confirms the device will essentially 'stay in its lane' and not interfere with other radios when operating." The reports we found are tests of the IEEE 802.15.4 transmitter functionality -- 802.15.4 is the radio standard Thread runs on. While it supports a number of technologies, the reports mention Thread explicitly.

Thread is the primary wireless protocol for the new smart home standard Matter, which Apple helped develop and that is now the underlying architecture for its Apple Home smart home platform. A low-power, low-bandwidth, mesh networking protocol specifically designed for IoT devices, Thread is shown to be faster than Bluetooth and offers better range, making it ideal for connecting products like smart lights, locks, thermostats, and sensors. [...] So why is it there? The Apple Home app runs on Macs and iPads, and Thread radios could allow them to communicate directly with smart home devices and act as Thread border routers. It's possible Apple is planning to turn your Mac or iPad into a home hub, but iPads used to be home hubs, and the company discontinued that capability for its new Apple Home architecture. Those iPads didn't have Thread radios, though.
