The Chinese Academy of Sciences claims to have realized a 2Mbit per second internet connection that transmits data simply by modulating the flicker of the little diodes, and imperceptibly enough to have them serve as room lighting as well. Like Boston University before them, the Chinese scholars see short-range LED networks controlling smart appliances.
Chinese scientists enable 2Mbps Internet over LED
Posted on Wednesday, May 19 2010 @ 9:11 CEST by Thomas De MaesschalckEngadget spotted that Chinese researchers have figured out a way to achieve a 2Mbps wireless Internet connection via ceiling-mounted blue LEDs. The systems works by modulating the flicker of the diodes and picking up the data stream with a line-of-sight networking receiver. According to the report, the flickering should be imperceptible by humans.
