Harald Haas’s Li-Fi Vision: Light Bulbs That Transmit Data
“That’s a video, a high-definition video that is transmitted through that light beam.”
Huh?
It’s been dubbed “Li-Fi,” and last month, Harald Haas, Chair of Mobile Communications in the Institute for Digital Communications at the University of Edinburgh, gave an eye-popping demonstration of what he’s been developing during a TED talk on “Wireless data from every light bulb”.
Haas is, as his bio puts it, “the pioneer behind a new type of light bulb that can communicate as well as illuminate.”
At about 6 minutes into the 13 minute presentation, Haas gives his first public demonstration of how it works. If you don’t have time to watch the whole talk, watch at least the 90 seconds from 5:50 to 7:20. Haas shows how a beam from a light bulb can be rigged up to transmit a high definition video stream:
