Forget WiFi and Radio Waves, LiFi Uses Lightbulbs to Connect to the Internet

Whether you're using wireless internet in a coffee shop, stealing it from the guy next door, or competing for bandwidth at a conference, you've probably gotten frustrated at the slow speeds you face when more than one device is tapped into the network. As more and more people - and their many devices - access wireless internet, clogged airwaves are going to make it increasingly difficult to latch onto a reliable signal.

One German physicist, Harald Haas, has come up with a solution he calls "data through illumination" - taking the fiber out of fiber optics by sending data through an LED lightbulb that varies in intensity faster than the human eye can follow. It's the same idea behind infrared remote controls, but far more powerful. More..
