Harald Haas: Wireless data from every light bulb (TED)

Original website : TED.com www.ted.com About this talk : 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. About the speaker : Harald Haas Harald Haas is the pioneer behind a new type of light bulb that can communicate as well as illuminate -- access the Internet using light instead of radio waves.
