Wireless LED System

The newest technology in the lighting world involves integrating LED lighting fixtures with wireless internet connectivity, but just where is this trend going? What’s next? Ingenious Scottish boffins have invented a solar-panel-powered version of their data networking kit that uses light to shift bits wirelessly. The team, based at the University of Edinburgh, first called its technology D-Light, short for data light, and its existence was revealed exclusively by your humble correspondent during a previous life at the Sunday Herald. The tech, dubbed Li-Fi, modulates the output of LEDs to send information through the air to a photo-detector. The next logical step for the academics is powering the kit with solar panels. Professor Harald Haas, who came up with the Li-Fi idea, said this week: "Solar-powered Li-Fi could make internet access available in far-flung places, and opens up all sorts of possibilities for widespread wireless communications." Read the whole story at The Register.
