Say it with light: Using LEDs to move data faster

Say with life

It’s like using fiber optics to communicate – only without the fiber.

Imagine connecting to the Internet through the same room lights that brighten your day. A University of Virginia engineering professor and her former graduate student are already there.

Maite Brandt-Pearce, a professor in the Charles L. Brown Department of Electrical and Computer Engineering, and Mohammad Noshad, now a postdoctoral fellow in the Electrical Engineering Department at Harvard University, have devised a way of using from light-emitting diode fixtures to carry signals to wireless devices at 300 megabits per second from each light. It’s like having a whole wi-fi system all to yourself; using light waves, there would be more network access points than with , so less sharing of the wireless network.
