Broadband arrives via light switches

We figure that once you are done reading this post, you will never look at light switches in the same way ever again. After all, German scientists are thinking of sending wireless broadband signals through light that comes in to your home by some encoding. This theory is the brainchild of Jelena Vucic and colleagues at the Fraunhofer Institute for Telecommunications. Assuming they are able to optimize the synergy of light and data, they will be able to exploit the higher bandwidths by generating a signal in a room by slightly flickering all the lights in unison. Using such a technique, the team claims that tests have shown it to hit data bandwidth rates of 230Mbps – talk about a record where visible wireless is concerned!
