1Gbps Optical Wireless Network Might Replace Wi-Fi

Posted by timothy on Saturday January 30, 2010 @07:20AM from the line-of-sight-and-bouncy-bouncy dept.

Mark.JUK writes "Pennsylvania State University has developed a new method of indoor Optical Wireless network that does not require a line-of-sight and runs at speeds of 1Gbps+. The system uses a high-powered laser diode — a device that converts electricity into light — as the optical transmitter and an avalanche photo diode — a device that converts light to electricity — as the receiver. The light bounces off the walls and is picked up by the receiver. Traditional radio frequency systems (Wi-Fi , WiMAX etc.) do not require line of sight transmission, but can pass through some substances and so present a security problem. Light, in a room without windows, will not escape the room, improving security."

As usual, Windows makes networking less secure, why am I not surprised.
