This Wi-Fi is 100 times faster, never slacks

London, March 19: Even if you have the very best Wi-Fi system available, you won t get more than 300Mb it per second speed in total.However, researchers now claim to have achieved Wi-Fi at a lightning speed of 42.8Gb it per second which is 100 times faster.The team from Eindhoven University of Technology in the Netherlands came up with a surprising solution to beat slow Wi-Fi: a wireless network based on harmless infrared rays.The capacity is not only huge (more than 40Gbit/s per ray) but also there is no need to share since every device gets its own ray of light, said lead researcher Joanne Oh.Oh managed a speed of 42.8Gbit/s over a distance of 2.5 metres.For comparison, the average connection speed in the Netherlands is two thousand times less (17.6Mbit/s).The Eindhoven system has so far used the light rays only to download; uploads are still done using radio signals.The system conceived in Eindhoven is simple and, in principle, cheap to set up.The wireless data comes from a few central light antennas , for instance mounted on the ceiling, which are able to precisely direct the rays of light supplied by an optical fibre.Since there are no moving parts, it is maintenance-free and needs no power.The antennas contain a pair of gratings that radiate light rays of different wavelengths at different angles.If you walk around as a user and your smartphone or tablet moves out of the light antenna s line of sight, then another light antenna takes over.Moreover, there is no longer any interference from a neighbouring Wi-Fi network, the researchers noted.The work of Oh is part of the wider BROWSE project headed by professor of broadband communication technology Ton Koonen, and with funding from the European Research Council.
