Infrared system could deliver 40 Gbps wireless networks

Wi-Fi works by sending information via radio waves, but systems that rely on light – be it infrared or visible – have the potential to achieve much faster speeds. A system proposed by a team at Eindhoven University of Technology (TU/e) uses infrared rays beamed down from antennas in the ceiling and is claimed to be capable of data transfer rates of over 40 Gbps, regardless of how many devices are hooking into the network.
Beaming radio waves of either 2.5 GHz or 5 GHz, regular Wi-Fi can reach transfer speeds of about 300 Mbps at most, but the average is far lower than that.
