LED Data Transmission - LEDs are efficient and less polluting than compact fluorescent light bulbs, and come with a host of other advantages. Because LEDs can cycle on and off millions of times per second, they can, in effect, become wireless routers for information transport. The researchers used Ostar LEDs, which is one of the brightest LEDs available. The lights are modulated at a frequency that enables high-speed data transmission. It may transfer up to 200 Mbs.
