Chinese telecom giant Huawei, which has been caught in the crossfires of the Washington-Beijing trade war, on Saturday unveiled a new smart television, the first product to use its own operating system.The television will be available from Thursday in China and marks the first use of HarmonyOS, chief executive George Zhao said, adding that it will be marketed by its mid-range brand, Honor.Huawei revealed its highly-anticipated HarmonyOS on Friday as an alternative operating system for phones and other smart devices in the event that looming US sanctions prevent the firm from using Android technology.American companies are theoretically no longer allowed to sell technology products to Huawei, but a three-month exemption period -- which ends next week -- was granted by Washington before the measure came into force.That ban could stop the tech giant from getting hold of key hardware and software, including smartphone chips and elements of the Google Android operating system, which runs the vast majority of smartphones in the world, including Huawei's.Huawei -- considered the world leader in fast fifth-generation or 5G equipment and the world's number two smartphone producer -- has been blacklisted by US President Donald Trump amid suspicions it provides a backdoor for Chinese intelligence services, which the firm denies.

This week the Center for Media Justice, ColorOfChange.org, and New America’s Open Technology Institute filed a complaint with the Federal Communications Commission alleging the Baltimore police are violating the federal Communications Act by using cell site simulators, also known as Stingrays, that disrupt cellphone calls and interfere with the cellular network—and are doing so in a way that has a disproportionate impact on communities of color. Stingrays operate by mimicking a cell tower and directing all cellphones in a given area to route communications through the Stingray instead of the nearby tower. They are especially pernicious surveillance tools because they collect information on every single phone in a given area—not just the suspect’s phone—this means they allow the police to conduct indiscriminate, dragnet searches. They are also able to locate people inside traditionally-protected private spaces like homes, doctors’ offices, or places of worship. Stingrays can also be configured to capture the content of communications. Because Stingrays operate on the same spectrum as cellular networks but are not actually transmitting communications the way a cell tower would, they interfere with cell phone communications within as much as a 500 meter radius of the device (Baltimore’s devices may be limited to 200 meters). This means that any important phone call placed or text message sent within that radius may not get through. As the complaint notes, “[d]epending on the nature of an emergency, it may be urgently necessary for a caller to reach, for example, a parent or child, doctor, psychiatrist, school, hospital, poison control center, or suicide prevention hotline.” But these and even 911 calls could be blocked.

The Baltimore Police Department could be among the most prolific users of cell site simulator technology in the country. A Baltimore detective testified last year that the BPD used Stingrays 4,300 times between 2007 and 2015. Like other law enforcement agencies, Baltimore has used its devices for major and minor crimes—everything from trying to locate a man who had kidnapped two small children to trying to find another man who took his wife’s cellphone during an argument (and later returned it). According to logs obtained by USA Today, the Baltimore PD also used its Stingrays to locate witnesses, to investigate unarmed robberies, and for mysterious “other” purposes. And like other law enforcement agencies, the Baltimore PD has regularly withheld information about Stingrays from defense attorneys, judges, and the public. Moreover, according to the FCC complaint, the Baltimore PD’s use of Stingrays disproportionately impacts African American communities. Coming on the heels of a scathing Department of Justice report finding “BPD engages in a pattern or practice of conduct that violates the Constitution or federal law,” this may not be surprising, but it still should be shocking. The DOJ’s investigation found that BPD not only regularly makes unconstitutional stops and arrests and uses excessive force within African-American communities but also retaliates against people for constitutionally protected expression, and uses enforcement strategies that produce “severe and unjustified disparities in the rates of stops, searches and arrests of African Americans.”

Adding Stingrays to this mix means that these same communities are subject to more surveillance that chills speech and are less able to make 911 and other emergency calls than communities where the police aren’t regularly using Stingrays. A map included in the FCC complaint shows exactly how this is impacting Baltimore’s African-American communities. It plots hundreds of addresses where USA Today discovered BPD was using Stingrays over a map of Baltimore’s black population based on 2010 Census data included in the DOJ’s recent report:

28 March 2011 -- The Web and television convergence story was the focus of W3C's Second Web and TV Workshop, which took place in Berlin in February. Today, W3C publishes a report that summarizes the discussion among the 77 organizations that participated, including broadcasters, telecom companies, cable operators, OTT (over the top) companies, content providers, device vendors, software vendors, Web application providers, researchers, governments, and standardization organizations active in the TV space. Convergence priorities identified in the report include: Adaptive streaming over HTTP Home networking and second-screen scenarios The role of metadata and relation to Semantic Web technology Ensuring that convergent solutions are accessible. Profiling and testing Possible extensions to HTML5 for Television

The 802.22TM-2011 standard will be used on frequencies that were used by analog television channels, but were freed up when the U.S. transitioned to digital television broadcasting over the air. Known as “white spaces” technology, the wireless standard supports transmissions speeds topping out at 22 Mbps per channel, with a range of up to 100 kilometers.

Unlike the frequencies used by cellular network operators, the white spaces use unlicensed spectrum (just like today’s Wi-Fi networks), so a wide range of compatible devices are expected from many companies. This would make it far easier and cheaper for those in remote areas to gain faster Internet access, for example.
