  • The Terrifying Potential of the 5G Network | The New Yorker
    https://www.newyorker.com/news/annals-of-communications/the-terrifying-potential-of-the-5g-network

    Two words explain the difference between our current wireless networks and 5G: speed and latency. 5G—if you believe the hype—is expected to be up to a hundred times faster. (A two-hour movie could be downloaded in less than four seconds.) That speed will reduce, and possibly eliminate, the delay—the latency—between instructing a computer to perform a command and its execution. This, again, if you believe the hype, will lead to a whole new Internet of Things, where everything from toasters to dog collars to dialysis pumps to running shoes will be connected. Remote robotic surgery will be routine, the military will develop hypersonic weapons, and autonomous vehicles will cruise safely along smart highways. The claims are extravagant, and the stakes are high. One estimate projects that 5G will pump twelve trillion dollars into the global economy by 2035, and add twenty-two million new jobs in the United States alone. This 5G world, we are told, will usher in a fourth industrial revolution.

    A totally connected world will also be especially susceptible to cyberattacks. Even before the introduction of 5G networks, hackers have breached the control center of a municipal dam system, stopped an Internet-connected car as it travelled down an interstate, and sabotaged home appliances. Ransomware, malware, crypto-jacking, identity theft, and data breaches have become so common that more Americans are afraid of cybercrime than they are of becoming a victim of violent crime. Adding more devices to the online universe is destined to create more opportunities for disruption. “5G is not just for refrigerators,” Spalding said. “It’s farm implements, it’s airplanes, it’s all kinds of different things that can actually kill people or that allow someone to reach into the network and direct those things to do what they want them to do. It’s a completely different threat that we’ve never experienced before.”

    Spalding’s solution, he told me, was to build the 5G network from scratch, incorporating cyber defenses into its design.

    There are very good reasons to keep a company that appears to be beholden to a government with a documented history of industrial cyber espionage, international data theft, and domestic spying out of global digital networks. But banning Huawei hardware will not secure those networks. Even in the absence of Huawei equipment, systems still may rely on software developed in China, and software can be reprogrammed remotely by malicious actors. And every device connected to the fifth-generation Internet will likely remain susceptible to hacking. According to James Baker, the former F.B.I. general counsel who runs the national-security program at the R Street Institute, “There’s a concern that those devices that are connected to the 5G network are not going to be very secure from a cyber perspective. That presents a huge vulnerability for the system, because those devices can be turned into bots, for example, and you can have a massive botnet that can be used to attack different parts of the network.”

    This past January, Tom Wheeler, who was the F.C.C. chairman during the Obama Administration, published an Op-Ed in the New York Times titled “If 5G Is So Important, Why Isn’t It Secure?” The Trump Administration had walked away from security efforts begun during Wheeler’s tenure at the F.C.C.; most notably, in recent negotiations over international standards, the U.S. eliminated a requirement that the technical specifications of 5G include cyber defense. “For the first time in history,” Wheeler wrote, “cybersecurity was being required as a forethought in the design of a new network standard—until the Trump F.C.C. repealed it.” The agency also rejected the notion that companies building and running American digital networks were responsible for overseeing their security. This might have been expected, but the current F.C.C. does not consider cybersecurity to be a part of its domain, either. “I certainly did when we were in office,” Wheeler told me. “But the Republicans who were on the commission at that point in time, and are still there, one being the chairman, opposed those activities as being overly regulatory.”

    Opening up new spectrum is crucial to achieving the super-fast speeds promised by 5G. Most American carriers are planning to migrate their services to a higher part of the spectrum, where the bands are big and broad and allow for colossal rivers of data to flow through them. (Some carriers are also working with lower-spectrum frequencies, where the speeds will not be as fast but likely more reliable.) Until recently, these high-frequency bands, which are called millimetre waves, were not available for Internet transmission, but advances in antenna technology have made it possible, at least in theory. In practice, millimetre waves are finicky: they can only travel short distances—about a thousand feet—and are impeded by walls, foliage, human bodies, and, apparently, rain.

    Deploying millions of wireless relays so close to one another and, therefore, to our bodies has elicited its own concerns. Two years ago, a hundred and eighty scientists and doctors from thirty-six countries appealed to the European Union for a moratorium on 5G adoption until the effects of the expected increase in low-level radiation were studied. In February, Senator Richard Blumenthal, a Democrat from Connecticut, took both the F.C.C. and F.D.A. to task for pushing ahead with 5G without assessing its health risks. “We’re kind of flying blind here,” he concluded. A system built on millions of cell relays, antennas, and sensors also offers previously unthinkable surveillance potential. Telecom companies already sell location data to marketers, and law enforcement has used similar data to track protesters. 5G will catalogue exactly where someone has come from, where they are going, and what they are doing. “To give one made-up example,” Steve Bellovin, a computer-science professor at Columbia University, told the Wall Street Journal, “might a pollution sensor detect cigarette smoke or vaping, while a Bluetooth receiver picks up the identities of nearby phones? Insurance companies might be interested.” Paired with facial recognition and artificial intelligence, the data streams and location capabilities of 5G will make anonymity a historical artifact.

    To accommodate these limitations, 5G cellular relays will have to be installed inside buildings and on every city block, at least. Cell relays mounted on thirteen million utility poles, for example, will deliver 5G speeds to just over half of the American population, and cost around four hundred billion dollars to install. Rural communities will be out of luck—too many trees, too few people—despite the F.C.C.’s recently announced Rural Digital Opportunity Fund.

  • Four Dead-Simple Ways to Improve Home #wifi Performance
    https://hackernoon.com/four-dead-simple-ways-to-improve-home-wifi-performance-b1f1de0950bd?sour

    Photo: escapejaja / Adobe StockOver the past decade, WiFi has become the internet connection medium of choice that keeps us all connected to our digital lives. As wireless internet access has grown, so too has the number and type of devices we expect our wireless networks to accommodate, and spectrum congestion is becoming an intractable problem in many places. That’s one of the major reasons that hardware vendors are so keen to introduce the new WiFi 6 standard into the market, which is designed from the ground up to cope with congested wireless environments and an ever-larger number of simultaneous device connections.Of course, it’s unrealistic to expect that WiFi 6 is going to become the dominant type of wireless network overnight — especially when you consider the fact that there are (...)

  • China’s #Xinjiang Province: A Surveillance State Unlike Any the World Has Ever Seen - SPIEGEL ONLINE
    http://www.spiegel.de/international/world/china-s-xinjiang-province-a-surveillance-state-unlike-any-the-world-has-ever

    At the same time, Beijing is equipping the far-western province with state-of-the-art #surveillance technology, with cameras illuminating every street all over the region, from the capital Urumqi to the most remote mountain village. Iris scanners and WiFi sniffers are in use in stations, airports and at the ubiquitous checkpoints — tools and programs that allow data traffic from wireless networks to be monitored.

    The data is then collated by an “integrated joint operations platform” that also stores further data on the populace — from consumer habits to banking activity, health status and indeed the DNA profile of every single inhabitant of Xinjiang.

  • Meet the People Building Their Own Internet in Detroit - VICE Video : Documentaries, Films, News Videos
    https://video.vice.com/en_us/video/motherboard-dear-future-people-building-their-own-internet-detroit/59cebd5795073d0905939aeb

    When it comes to the internet, our connections are generally controlled by telecom companies. But a group of people in Detroit is trying to change that. Motherboard met with the members of the Equitable Internet Initiative (EII), a group that is building their own wireless networks from the ground up in order to provide affordable and high-speed internet to prevent the creation of a digital class system.

      une histoire #triste supplémentaire à ajouter au systématique #dénigrement_des_femmes

      3. The idea wasn’t adopted at the time, in part due to skepticism that an actress could contribute to technology

      When Lamarr and Antheil approached the National Inventors’ Council to present their device, they were rebuffed. The council suspected it would be too cumbersome to implement the communication system in military crafts.

      She was also rebuffed in her direct attempts to help the war effort. When she offered her expertise in wartime technology to the council, she was denied. They suggested that the “most beautiful woman in films” could make a bigger difference by acting as a spokeswoman for war bonds.
      4. Today, the invention is fundamental to wi-fi, bluetooth technology, and other wireless networks

      In the 1950s, engineers at Sylvania Electric Products began looking seriously at the neglected patent. By the early 1960s, they completed the technology to finally implement frequency hopping – not with a bulky mechanical apparatus, as in the patent, but with an electric signal processing system.
