A recent TedTalk about LED lights has garnered about a million and a half views. That high number isn’t surprising, given that LEDs have been making headlines a lot, lately. Tons of informational articles about the efficiency of LED light bulbs and how to choose them have been circulating online. But this TedTalk is about something quite different – data transmission.
The talk was given by Harold Haas, Chair of Mobile Communications at the University of Edinburgh, who coined the term LiFi, or light fidelity, to refer to a visible light communications (VLC) system. LiFi uses LEDs, which, of course, are electronic semi-conductors, as a medium to deliver networked, mobile, high-speed communication.
