    In 2016, Huawei sued Samsung in both China and the US for allegedly infringing on multiple wireless communication patents, and today a Shenzhen judge ruled against Samsung. The court ordered Samsung to stop selling any product using technology protected by the one patent it found the company to have violated and ordered Samsung to pay a small court fee.

  • Flexible wireless charging sheet could eventually turn your skinny jeans into power pants (video)

    If you haven't already heard, wireless charging is all the rage -- cars, cameras, and, of course, cellphones have all benefited from the burgeoning technology. Now a team of researchers at Japan's National Institute of Information and Communications Technology (NICT) are showing off a 2D power transmission system that could turn your pockets into wireless charging stations. According to its creators, "When a 2.4GHz high frequency signal is transmitted through the sheet, it becomes a wireless conductive object." Electromagnetic waves are captured in the sheet and can be concentrated in particular areas, allowing for individual activation of multiple devices, and thus increasing efficiency -- systems like Qi currently require a dedicated transmitter per device. The NICT says the power it provides is still relatively weak -- about 1W -- but it has plans to eventually bring the technology to soft fabrics. So maybe that Snuggie charging station you've been dreaming of isn't so impractical after all.

  • Sony develops 11Gbps short-range wireless intra-connection

    Before you get too excited about the bandwidth number, you should know that Sony's latest wireless innovation works at a range of up to 14 millimeters. So no, it won't be replacing your WiFi antenna anytime soon, but it may well be showing up in your next television set or other bit of Sony-branded gadgetry. Working in the 30GHz to 300GHz frequency range, this is designed to replace wired communication channels inside electronic devices, with Sony claiming it will deliver "advantages such as size and cost-reduction and enhanced reliability of the final product." Basically, erecting 1mm antennae that can beam information at each other at a rate of 11Gbps turns out to be simpler and more reliable than printing ever wider data lanes into the circuit board. Makes sense to us. Full PR after the break.
