Wireless Data From Every Light Bulb

HHere's an idea: imagine if you could transmit data using light - through the air, not down a cable.

Visible light communication. Terabytes of data, in parallel...and you could utilise existing lighting infrastructure to transmit that data. You can control it easily by the direction of the beam and the throw of the light creates robust transmission zones, so even with interference it should get through. Highly efficient and highly powerful. Professor Harald Haas from the University of Edinburgh (and also honorary professor at Jacobs University of Bremen) demonstrates just such a revolutionary idea here, known as 'Optical Wirelss Communication' using non-coherent LEDs.

It should be very interesting to see how this develops...
