Chinese scientists demonstrate 2Mbps internet over LED light bulbs


smart LED WiFi bulbs

LED data transmission used to be all the rage — we fondly remember beaming Palm Pilot contacts via IrDA. Then we got omni-directional Bluetooth and building-penetrating WiFi, and put all that caveman stuff behind us. But now, scientists the world over are looking to bring back line-of-sight networking, and the latest demonstration has Chinese researchers streaming video to a laptop with naught but ceiling-mounted blue LEDs. 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. It’s not quite the gigabit speed you’d get from laser diodes, but this way you’ll get more mileage out of those expensive new bulbs, eh?

    I have been surfing online greater than three hours as of late, yet I by no means found any attention-grabbing article like yours. It’s pretty price sufficient for me. In my opinion, if all webmasters and bloggers made good content as you probably did, the web shall be a lot more helpful than ever before.
