To network the average football stadium, you’d start by planting a tower right in the center of the field – guaranteeing great coverage for the athletes on the field, and crummy signal strength for fans sitting as far from it as possible. To improve things, you’d probably scatter signal repeaters throughout the seats, and maybe attach them to the walkways that encircle the stadium, and stick a few at the edge of the field, and …. Waitaminute. How do you connect all of that junk?
“You would end up with a hundred cables! It would be a spaghetti monster that would be just catastrophe,” Pål Frenger, an expert in radio network energy performance at Ericsson Research, told Digital Trends.
To facilitate better networking at challenging locations such as arenas, historic sites, and dense urban environments, Frenger and colleagues invented what they call “Radio Stripes” – essentially packing tape with serialized radios every foot or so and linked by flexible wire. To deploy, simply unroll and affix.
It would be a spaghetti monster that would be just catastrophe.”
The idea is a little slice of genius, combining not just antennas and network cable but addressing power deployment as well. The new frequencies and shrinking size of antennas (Ericsson says researchers can make them the size of a small matchbox) permit network access points to become ubiquitous, the company explains, but the actual deployment remains a challenge. Adhesive tape may be the answer. The product can be affixed easily and is potentially just as simple to remove, or you could install it under moldings or carpeting, or inside the frame of a building as it is being assembled.
“We have this idea of making network rollouts super simple,” Frenger joked — taking a roll of the tape and simply rolling out a few feet on the floor.
Ericsson president and CEO Börje Ekholm unveiled the technology during an opening day presentation at the Mobile World Congress 2019 show in Barcelona, pulling a wad of the tape from his pocket and waving it around like ribbon from a birthday present. At the event, Ekholm declared that 5G – short for fifth-generation networking — was no longer simply marketing hype but reality.
“We are as of today rolling out 5G networks in North America with live traffic,” explained Börje Ekholm, Ericsson president and CEO. “The technology is here and there is more to come. We are truly switching on 5G in 2019.”
AI companies spend enormous amounts of time convincing us their technology is safe and secure. But what happens when those same companies become targets of increasingly sophisticated AI-powered attacks? Anthropic, the company behind Claude, is now facing that question. According to a Washington Post report, cybersecurity startup Cathedral discovered vulnerabilities that let its researchers access sensitive information in Anthropic's internal systems.
The researchers used AI agents to identify potential entry points in less than 12 hours. Interestingly, they didn't need to crack Claude itself. Instead, they exploited weaknesses in third-party business applications that Anthropic uses for everyday operations. Anthropic's security testing program disclosed the findings, which allows outside researchers to identify and report vulnerabilities.
Military working dogs charge into places the rest of us would flee. So, I understand why anyone would want to breed tougher, healthier dogs for the job.
Warhound, a new startup from Colossal Biosciences co-founder Ben Lamm and Anduril co-founder Palmer Luckey, has stepped out of stealth with $200 million to clone and gene-edit working dogs for American troops, police departments, and emergency services (via TechCrunch).
AI can describe a picture, identify objects, and answer questions about what a camera sees. But when a blind user needs a quick answer, getting an entire spoken essay about the scene isn't exactly helpful. Researchers at the University of Maryland (UMD) have found that AI-powered visual assistance can leave blind users doing too much work to get the information they actually need.
The study, titled Say It My Way: Exploring Control in Conversational Visual Question Answering with Blind Users, examined how people interact with Be My AI, an AI-powered feature of the Be My Eyes app. The researchers found that users often received lengthy descriptions that didn't adequately address their immediate goals, forcing them to ask follow-up questions or find ways to steer the AI towards a more useful answer.
