1Gbps Optical Wireless Network Might Replace Wi-Fi

Posted by timothy on 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.

    what if you open the door? Will internet leak out of the room?

    I suppose a double door or, more entertainingly, a revolving door, could help with this...

    Have a look at this. We're intercepting an electromagnetic signal in the terahertz range and it seem to have some kind of beating. I think we just might have found a pulsar!
