An anonymous reader quotes a report from Fast Company: Motorola Solutions (not to be confused with Motorola Mobility, which makes the smartphones you know), the biggest global player in these LMR walkies, is releasing what appears to be the most advanced walkie-talkie ever. Called the APX Next, it's a chunky black brick with a thick antenna and a giant push-to-talk button on its side. Much like an iPhone, it also features a touchscreen on its front -- but don't be distracted by that. Its real innovation was born from 2,000 hours of interviews and testing with more than 50 emergency service agencies, including SWAT teams and detectives. It's a voice-recognition system that can operate in extremely loud environments, with artificial intelligence software that can look up 95 of the most common things a police officer or firefighter would call into dispatch -- like a driver's license, or license plate -- without any human operator on the other end of the line. But its ultimate promise is simply to free up the user's hands as much as possible, ensuring that someone is as safe and capable as possible during an emergency.

APX Next is a walkie-talkie and a cellphone combined. It has both the high-powered radio chip for land communications and a low-powered 4G/LTE chip for cell-tower data. These two chips can work at the same time, which is an engineering challenge, especially because the walkie-radio has 25 times the wattage of the 4G chip. The core buttons, including the large talk button, are all designed as you'd expect, to ensure they can be used without looking, and purely by muscle memory in stressful situations. Four separate microphones capture your voice, with programming designed specifically to cancel out exceptionally loud noises. But it isn't always listening for a wake word like the Echo or Google Home. You need to hit a button to cue the assistant. The company says it's using unnamed third parties to handle the natural language processing in the cloud. "What Motorola did was train the model specifically to handle things like ten-codes and even regionally specific dialects across the U.S," the report says.

"Once a question is sent to the cloud, the AI is able to scour a city or force's database for the same private information a dispatcher would be looking up." What's also neat is that the AI won't automatically read sensitive information out loud. Instead, the radio will beep when it has an answer, and the user can get to a private place, if they wish, before hitting a button to hear the results.

IEEE Spectrum describes how the U.S. Defense Advanced Research Projects Agency (DARPA) partnered with Pivot Technology Services to help them relocate their massive radio-frequency emulation testbed, called "Colosseum." The testbed was built for the agency's Spectrum Collaboration Challenge (SC2) -- a three-year competition to demonstrate the validity of using AI to work together in order to use wireless spectrum more efficiently than operating on pre-allocated bands. Slashdot reader Wave723 shares an excerpt from the report: Colosseum was originally built and housed at Johns Hopkins University Applied Physics Laboratory. That changed at the beginning of October, when the testbed was dismantled and later trucked to Los Angeles for the competition's finale, scheduled to begin at 3:30pm PDT today at MWC Los Angeles. [...] There may have been some molehills during the checks, but moving Colosseum definitely qualifies as a mountain. The testbed uses 3 Peta-Ops per second of computing power and 52 terabytes per second of data to emulate 65,000 channel operations between 256 wireless devices. It can draw up to 92 kilowatts of power and requires 200 gallons of water per minute to cycle through its cooling system to keep it from overheating.

Colosseum is housed within a space twice of the size of a cargo container -- in fact, its housing is literally built from two converted cargo containers put side by side. The halves arrived at the Los Angeles Convention Center during the set-up for MWC Los Angeles, and were hauled into the building and onto the convention floor by two 18-wheelers. We're going to move right past the crazy fact that DARPA and its hired logistics companies drove two semi-trucks into the Los Angeles Convention Center, because it gets better. To actually lower Colosseum's halves onto the ground, the next step involved something that both Tilghman and Gabel referred to as a "forklift ballet." As it turned out, the convention center didn't have a forklift strong enough to lift either half, so everyone improvised and used four smaller forklifts simultaneously by carefully arranging them around each half of Colosseum. It worked, but Gabel, in showing me a video of the forklift ballet, pointed out a moment where one of the forklift's rear wheels lifted off the ground as the machine and its operator grappled with Colosseum's weight...

Physicists at Stockholm University and the Max Planck Institute of Physics have proposed a novel design for an "axion radio" that employs cold plasmas (gases or liquids of charged particles) to "listen" for dark matter. Their paper has been published in the journal Physical Review Letters. Ars Technica reports: "Finding the axion is a bit like tuning a radio: you have to tune your antenna until you pick up the right frequency," said co-author Alexander Millar, a postdoc at Stockholm University. "Rather than music, experimentalists would be rewarded with 'hearing' the dark matter that the Earth is traveling through." [...] According to quantum mechanics, particles can exhibit wavelike behavior as well as particle characteristics. So an axion would behave more like a wave (or wave packet) than a particle, and the size of the wave packets is inversely proportional to their mass. That means these very light particles don't necessarily need to be tiny. The downside is that they interact even more weakly with regular matter than [weakly interacting massive particles], or WIMPS, so they cannot be produced in large colliders -- one current method for detecting WIMPs.

Physicists don't know what the axion's mass might be, so there's a broad parameter space in which to search, and no single instrument can cover all of it, according to co-author Matthew Lawson, also a postdoc at Stockholm University. That's why physicists have been developing all kinds of smaller experiments for detecting axions, from atomic clocks and resonating bars, to shining lasers at walls on the off-chance a bit of dark matter seeps through the other side. Yet most instruments to date are capable of detecting axions only within a very limited mass range. [...] Lawson et al. have come up with an innovative design for a tunable plasma-based haloscope. Their proposed instrument exploits the fact that axions inside a strong magnetic field will generate their own small electric field. This in turn drives oscillations in the plasma, amplifying the signal. [...] At the moment, Lawson et al.'s design is theoretical, but several experimental groups are actively working on building prototypes. "The fact that the experimental community has latched onto this idea so quickly is very exciting and promising for building a full-scale experiment," said Millar.

Japan's sole pager provider, Tokyo Telemessage Inc, will shut down radio signals for its services Tuesday, ending support for the device first introduced in the country half a century ago. Japan Today reports: In recent years, the device had been favored mainly by those working in hospitals, where cellphone use was once discouraged because of concerns over the effect of electromagnetic waves on medical devices and where cellphone reception can sometimes be poor. Beeper services in Japan began in 1968 with the predecessor of Nippon Telegraph and Telephone Corp. Users would call a specific number via a landline, causing the device to emit a beeping sound. But from the late 1980s onward, the popularity of pagers grew as they could be used to send messages combining numbers and text characters.

The number of pager users exceeded 10 million in 1996, with the device becoming one of the defining symbols of a subculture among female high school students along with "loose socks" and taking photos in puri-kura photo booths. However, beeper services declined with the introduction of mobile phones. The number of pager users further decreased as e-mailing, texting as well as taking and sending pictures by phone became standard.

An anonymous reader quotes a report from Motherboard: Meet AdBlock Radio, an adblocker for live radio streams and podcasts. Its creator, Alexandre Storelli, told Motherboard he hopes to help companies "develop alternative business models for radio and podcast lovers that do not want ads." "Ads exploit the weaknesses of many defenseless souls," Storelli told Motherboard. "Ads dishonestly tempt people, steal their time and promise them a higher social status. Blocking them will be a relieving experience for many."

Most audio ads exploit "auditory artifacts" to produce an ad that can't be ignored or tuned out because it feels louder than it actually is -- this has gotten so bad that there has actually been a "sonic arms race" where ads have been made increasingly louder over the years. "Adblock Radio detects audio ads with machine-learning and Shazam-like techniques," Storelli wrote about the project. He said he's been working on it for more than three years and that it uses techniques such as speech recognition, acoustic fingerprinting, and machine learning to detect known ad formats. It uses a crowdsourced database of ads and "acoustic fingerprinting," which converts audio features into a series of numbers that can be combed by an algorithm. Storelli has made Adblock Radio open-source and given detailed instructions on how to build on it, integrate it into user devices, and deploy it in a way that pressures radio stations (and podcasts) to self-regulate the quality of their ads.

Newer Guy writes: Entercom Communications, one of the USA's largest radio broadcasting companies, has been hit with a ransomware-like incident. It apparently came in from a computer in the programming department and has taken out the company's email system and servers. All their radio stations across the country have been affected. The ransomware people demanded half a million dollars to restore things; Entercom refused to pay.

WFMU's Free Music Archive -- a digital library of high-quality and legal downloads that users could listen to, remix, and share -- is shutting down due to funding shortages. The Verge reports: "The future is uncertain, has been my mantra lately," says Cheyenne Hohman, who's been the director of the Free Music Archive since 2014. The shutdown date was initially the 9th, but has since been pushed back to November 16th because the FMA is in early talks with four different organizations that are interested in taking the project over. "The site may stay up a little bit longer to ensure, at the very least, that our collections are backed up on archive.org and the Wayback Machine." Even so, it's not a perfect solution. "If it just goes into archive.org, it's going to be there in perpetuity, but it's not going to be changing at all," Hohman says. "It's not going to be the same thing, that sort of community and project that it was for ... almost 10 years."

Sirius XM has agreed to buy online-music service Pandora for $3.5 billion, as the satellite-radio company looks to add streaming services in the increasingly competitive fight for listeners. From a report: According to the announcement, the deal will create "the world's largest audio-entertainment company," with more than $7 billion in projected revenue in 2018 and more than 100 million monthly listeners, combining SiriusXM's 36 million subscribers and Pandora's 70 million-plus monthly active users. It also moves SiriusXM and its parent company, Liberty Media, aggressively into the streaming market. The transaction is expected to close in the first quarter of 2019 and is subject to approval by Pandora stockholders; expiration or termination of any applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act and certain competition laws of foreign jurisdictions; and other customary closing conditions. On a call with analysts, Jim Meyer, Sirius XM's chief executive, said that the acquisition would enable Sirius to try to keep listeners who did not want to pay for music by diverting them toward Pandora's free ads-based model.

T-Mobile and Ericsson have signed a multi-year $3.5 billion agreement to build out T-Mobile's 5G infrastructure. The telecommunications company "will deploy Ericsson's Radio System portfolio, including 5G New Radio and NR hardware and software compliant with 3GPP standards," reports ZDNet. From the report: According to the companies, the contract also encompasses Ericsson's digital services solutions, including dynamic orchestration, business support systems or BSS, and Ericsson Cloud Core. Meanwhile, T-Mobile's already installed base of Ericsson Radio System radios will be able to run 5G NR technology via remote software installation. T-Mobile and Ericsson rival Nokia also announced a $3.5 billion 5G deal back in July. Add it up and T-Mobile is investing $7 billion in 5G between the two companies. As part the Nokia agreement, T-Mobile said it would use Nokia's 5G network technology including software, services and hardware. The carrier also said Nokia would help make its "600 MHz and 28 GHz millimeter wave 5G capabilities compliant with 3GPP 5G New Radio (NR) standards" -- echoing its current plans with Ericsson. In other 5G-related news, Verizon will begin offering installation of its 5G home broadband in select markets on October 1st. "Customers [in Houston, Indianapolis, Los Angeles, and Sacramento] will be able to begin ordering service once the installation is complete, with pricing set at $50 for Verizon Wireless customers and $70 for non-VZW customers," reports PhoneDog. Network speeds are expected to be around 300Mbps, with peak speeds nearing 1Gbps. There will also be no data caps.

An anonymous reader quotes a report from MIT Technology Review: David Anderson at Rydberg Technologies in Ann Arbor, Michigan, and a couple of colleagues, have reinvented the antenna from scratch. Their new device works in an entirely different way from conventional antennas, using a laser to measure the way radio signals interact with certain types of atoms. The secret sauce in the new device is Rydberg atoms. These are cesium atoms in which the outer electrons are so excited that they orbit the nucleus at great distance. At these distances, the electrons' potential energy levels are extremely closely spaced, and this gives them special properties. Indeed, any small electric field can nudge them from one level to another. Radio waves consist of alternating electric fields that readily interact with any Rydberg atoms they come across. This makes them potential sensors.

But how to detect this interaction? A gas made of Rydberg atoms has another property that turns out to be useful -- it can be made transparent by a laser tuned to a specific frequency. This laser essentially saturates the gas's ability to absorb light, allowing another laser beam to pass through it. However, the critical frequency at which this happens depends crucially on the properties of the Rydberg atoms in the gas. When these atoms interact with radio waves, the critical frequency changes in response. That's the basis of the radio detection. Anderson and co create a gas of cesium atoms excited into Rydberg states. They then use a laser tuned to a specific frequency to make the gas transparent. Finally, they shine a second laser through the gas and measure how much light is absorbed, to see how the transparency varies with ambient radio waves. The signal from a simple light-sensitive photodiode then reveals the way the radio signals are frequency modulated or amplitude modulated. The atomic radio can detect a huge range of signals -- over four octaves from the C band to the Q band, or wavelengths from 2.5 to 15 centimeters. It also should be less insensitive to electromagnetic interference due to its lack of conventional radio circuitry. "The atomic radio wave receiver operates by direct real-time optical detection of the atomic response to AM and FM baseband signals, precluding the need for traditional de-modulation and signal-conditioning electronics," say Anderson and co.

New submitter SteveSgt writes: A forum thread on QRZ.com indicates that the shortwave time broadcasts by the National Institute of Standards and Technology (NIST) from stations WWV (Colorado) and WWVH (Hawaii) may be slashed in budget year 2019. [One of the proposed reductions includes "$6.3 million supporting fundamental measurement dissemination, including the shutdown of NIST radio stations in Colorado and Hawaii."] While the WWV broadcasts may seem like an anachronism to some Slashdotters, they remain a crucial component in many unexpected services, from over-the-air broadcasters and traffic signals, to medical devices, wall clocks, and wrist watches. The signals serve as standard beacons for radio propagation, and as a frequency reference for alignment of a broad range of communications equipment. It's easy to imagine that not even the NIST knows every service and device that could be impacted by this decision.

The merger that once seemed all but inevitable has fallen apart. According to The Wall Street Journal, Tribune Media has terminated its merger agreement with rival TV station-owner Sinclair Broadcast Group (Warning: source may be paywalled; alternative source). The company is also suing Sinclair for failing to make sufficient efforts to get their $3.9 billion deal approved by regulators. From the report: The suit, filed in Delaware Chancery Court, alleges that Sinclair breached the merger agreement by engaging in "unnecessarily aggressive and protracted negotiations" with regulators over their requirement that Sinclair divest stations in certain markets to obtain approval, Tribune said in a statement. The deal structures Sinclair proposed, which Tribune said were done to allow it to maintain control over stations, created risks for the deal in violation of the merger agreement. Tribune is seeking financial damages.

The collapse of the deal and lawsuit mark a stunning turn of events for a deal that when it was announced in April of 2016 seemed certain to receive regulatory approval. "Our merger cannot be completed within an acceptable time frame, if ever, Tribune Media Chief Executive Peter Kern said in a statement. "This uncertainty and delay would be detrimental to our company and our shareholders. Accordingly, we have exercised our right to terminate the merger agreement, and, by way of our lawsuit, intend to hold Sinclair accountable." The merger hit the rocks last month when FCC commissioners voted to send the proposed sale to a judge. "FCC chairman Ajit Pai raised 'serious concerns' about Sinclair's selloff of 21 stations it had proposed in order to remain under station ownership limits post-merger," Engadget reported last month. "Had Sinclair declined to sell off some stations, its 173 broadcast stations in 81 markets, combined with Tribune's 42 stations in 33 markets would reach 72 percent of U.S. TV households."

T-Mobile has entered into a $3.5 billion multi-year agreement with Nokia to build out its 5G network. Nokia will supply T-Mobile with its end-to-end 5G technology, software, and services, including commercial AirScale radio platforms and cloud-native core, AirFrame hardware, CloudBand software, SON, and 5G Acceleration Services," reports PhoneDog. From the report: Nokia will help T-Mobile build a nationwide 5G network that'll use both 600MHz and 28GHz millimeter wave (mmWave) spectrum that'll be compliant with 3GPP 5G New Radio (NR) standards. T-Mobile has said that it'll deploy its 5G coverage in 30 cities in 2018, including New York City, Dallas, Los Angeles, and Las Vegas. The carrier's first 5G-capable smartphones are expected to arrive in early 2019. The T-Mobile announcement can be viewed here.

Last year, when Donald Trump appointed Ajit Pai chairman of the F.C.C., Pai promised to "take aggressive action" to stamp out pirates. In early May, the Preventing Illegal Radio Abuse Through Enforcement, or PIRATE, Act was introduced in Congress; it would increase fines from a maximum of a hundred and forty-four thousand dollars to two million dollars. But the stations aren't going away, The New Yorker reports. From the article: Transmission equipment has only become cheaper and more sophisticated. "The problem, as I see it, is that the technology has gone beyond what the law has been able to do," said David Goren, a local resident who works as a producer on licensed radio shows. Between 87.9 and 92.1 FM, Goren counted eleven illegal stations, whose hosts mainly spoke Creole or accented English. Pirates, he said, "offer a kind of programming that their audiences depend on. Spiritual sustenance, news, immigration information, music created at home or in the new home, here."

CaptainDork shares a report from Bleeping Computer: Starting yesterday, there have been numerous reports of people's Windows computers being infected with something called "All-Radio 4.27 Portable." After researching this heavily today, it has been determined that seeing this program is a symptom of a much bigger problem on your computer. If your computer is suddenly displaying the above program, then your computer is infected with malware that installs rootkits, miners, information-stealing Trojans, and a program that is using your computer to send send out spam.

Unfortunately, while some security programs are able to remove parts of the infection, the rootkit component needs manual removal help. Due to this, if you are infected with this malware, I strongly suggest that you create a malware removal help topic in our Virus Removal forum in order to receive one-on-one help in cleaning your computer. Some of the VirusTotal scans associated with this infection have also indicated that an information stealing Trojan could have been installed by this malware bundle as well. Therefore, it is strongly suggested that you change your passwords using a clean machine if you had logged into any accounts while infected. 6/29/18: The story has been updated to specify that this malware campaign is targeting Windows computers.

Researchers at the Massachusetts Institute of Technology have developed a new piece of software that uses wifi signals to monitor the movements, breathing, and heartbeats of humans on the other side of walls. While the researchers say this new tech could be used in areas like remote healthcare, it could in theory be used in more dystopian applications. Inverse reports: "We actually are tracking 14 different joints on the body [...] the head, the neck, the shoulders, the elbows, the wrists, the hips, the knees, and the feet," Dina Katabi, an electrical engineering and computer science teacher at MIT, said. "So you can get the full stick-figure that is dynamically moving with the individuals that are obstructed from you -- and that's something new that was not possible before." The technology works a little bit like radar, but to teach their neural network how to interpret these granular bits of human activity, the team at MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) had to create two separate A.I.s: a student and a teacher.

[T]he team developed one A.I. program that monitored human movements with a camera, on one side of a wall, and fed that information to their wifi X-ray A.I., called RF-Pose, as it struggled to make sense of the radio waves passing through that wall on the other side. The research builds off of a longstanding project at CSAIL lead by Katabi, which hopes to use this wifi tracking to help passively monitor the elderly and automate any emergency alerts to EMTs and medical professionals if they were to fall or suffer some other injury. For more information, a press release and video about the software are available.

The Amazon Echo and other smart speakers have helped push the audience for digital radio past that of FM and AM in the UK for the first time. According to Radio Joint Audience Research (RAJAR), digital listening has reached a new record share of 50.9%, up from 47.2% a year ago. This milestone will trigger a government review into whether the analog FM radio signal should be switched off altogether. iNews reports: The BBC said it would be "premature" to switch off the FM signal. It could cut off drivers with analogue car radios and disenfranchise older wireless listeners. Margot James, Digital minister, welcomed "an important milestone for radio." She confirmed that the Government will "work closely with all partners -- the BBC, commercial radio, (transmitter business) Arqiva, car manufacturers and listeners" before committing to a timetable for analogue switch-off.

James Purnell, BBC Director of Radio and Education, said: "We're fully committed to digital, and growing its audiences, but, along with other broadcasters, we've already said that it would be premature to switch off FM." Mr Purnell said that BBC podcast listening was up a third across all audiences since the same time last year, accounting now for 40,000 hours a week. But younger audiences have not inherited the habit of listening to "live" radio, even on digital.

Esther Schindler shares an article from Hewlett Packard Enterprise: Video may have killed the radio star, but other media certainly make old AM radio towers superfluous... maybe. "As once-loyal listeners tune away, most AM stations are barely holding onto life, slashing staff and budgets as deeply as they can while struggling to find a return to profitability," reports HPE. "Once upon a time, having a broadcast license of any kind was like having a permit to print money. In today's world, that's no longer true." But, with some 10,000 AM broadcast towers in the United States stretching high into the sky, there may be an opportunity for wireless carriers who don't want to argue with community opposition from neighborhoods where residents don't want yet another cell tower. The amount of money an AM station owner can pocket by sharing its tower with a wireless partner varies widely, depending on the tower's location, height, and several other factors. But it's certainly more income -- and a way to keep "old" technology from becoming obsolete. "Using an AM tower, which has very often been in place for many years, avoids many zoning and other permitting issues, versus going in and creating a new site for a tower," Behr explains. He says local residents, businesses, and officials rarely complain about an AM broadcast tower that suddenly begins serving as a cell site. "That tower was there before they were, and it doesn't bother them," Lawrence Behr, CEO of Greenville, North Carolina-based LBA Group, says. "Hanging a few things on it is rarely controversial, so that's a real good thing for AMs."

A vulnerability affecting emergency alert systems supplied by ATI Systems, one of the leading suppliers of warning sirens in the USA, could be exploited remotely via radio frequencies to activate all the sirens and trigger false alarms. From a report: "We first found the vulnerability in San Francisco, and confirmed it in two other US locations including Sedgwick County, Wichita, Kansas," Balint Seeber, Director of Threat Research at Bastille, told Help Net Security. "Although we have not visited other locations to confirm the presence of the vulnerability, ATI Systems has customers in the US and overseas from the military, local government, educational and energy sectors.

"ATI features customers on its website around the US including One World Trade Center, WestPoint Military Academy and Entergy Nuclear Indian Point which are all in New York State, UMASS Amherst in Massachusetts, Eastern Arizona College, University of South Carolina and Eglin Air Force Base in Florida, amongst others." The vulnerability stems from the fact that the radio protocol used to control the sirens is not secure: activation commands are sent "in the clear," i.e. no encryption is used.
