TEDTalks : Harald Haas - Wireless Data from Every Lightbulb

Summary:
What if every light bulb in the world could also transmit data? At TEDGlobal, Harald Haas demonstrates, for the first time, a device that could do exactly that. By flickering the light from a single LED, a change too quick for the human eye to detect, he can transmit far more data than a cellular tower - and do it in a way that's more efficient, secure and widespread.

Abstract:

What if every light bulb in the world could also transmit data? At TEDGlobal, Harald Haas demonstrates, for the first time, a device that could do exactly that. By flickering the light from a single LED, a change too quick for the human eye to detect, he can transmit far more data than a cellular tower - and do it in a way that's more efficient, secure and widespread.
