New method to transmit data wirelessly can send 2.5Tb/second

A team of American and Israeli researchers from the University of Southern California, NASA’s Jet Propulsion Laboratory, and Tel Aviv University have re-defined the concept of “fast” when it comes to wireless networks. Now, to put this figure into better perspective, ExtremeTech’s Sebastian Anthony writes that this is equivalent to 320 gigabytes per second, or around seven full Blu-ray movies per second. To achieve the feat, the researchers “twisted together eight ~300Gbps visible light data streams using OAM.” Reportedly, each of these eight beams has a different level of OAM twist. The beam is then transmitted over open space, and untwisted and processed by the receiving end.” According to Bo Thide, a Swedish physicist, OAM should allow us to twist together an “infinite number” of conventional transmission protocols without using any more spectrum.
