BBC Click (Technology): “Li-Fi: Could data transmission through a light-bulb replace Wi-Fi and broadband?”
Transmission: 16 August 2011
Visible light communication (VLC) uses rapid pulses of light to transmit information wirelessly. The team at Edinburgh is one of a number around the world who have used off the shelf LED’s to transmit data at very high speeds. Professor Harald Haas tells Click they have moved out of lab conditions and are able to use VLC in sun light – a major step forward. If this proves successful could Li-Fi may be ready to compete with conventional Wi-Fi.
