How do you make a wireless transmission that is as fast or even faster than most fibre - optic datum enactment ? With optical maser beams of course ! consort to aTechnology Review piece of music , super smart people at Battelle research in Columbus , Ohio estimate out a style , using millimetre undulation engineering , to send information at speeds up to 20 Gbit per second . They even arena test 10 Gbps at up to 800 measure . Even accounting for Ohio ’s unnervingly flat terrain , this is several hundred fourth dimension farther than a wireless transmission of that bandwidth had ever reachedbefore . Rather than dick around in the 10 - Gc frequency outer space — higher than most of today ’s phones and wireless data product , but still in the region of schematic radio — the Battelle squad figured out how to make a 100GHz frequency by “ modulat[ing ] information on two low - absolute frequency optical maser radio beam , then combin[ing ] the two . ” I knew crossing the stream of a proton gun could be sorry ; I did not know crossing laser beams modulated with data signal could be this good . I hypothesize the breakthrough does bode well for wireless equipment , but I ca n’t opine how any of this could run off of a lithium - ion battery . And , hey , would n’t laser phones make us all go blind ? OK , bright mass , please start out talk , cuz I ’m definitely over my head on this one . [ MIT Tech ReviewviaKurzweilAI.Net ]
