“If you look around, there are many LEDs around us. So there’s a rich infrastructure of LiFi transmitters around us,” Harald Hass, the director of the LiFi research and development center at the University of Edinburgh, said in a talk recently uploaded to TED.com.

In the TED Talk, which was filmed at TED Global>London in September, Mr. Hass demonstrated for the first time publicly that this is possible .
