Wi-Fi by LED light

Forget Fanny by Gaslight…an LED light went on for German physicist Harald Haas who suggests that we could utilise LED lightbulbs as an alternative route for connecting to the Internet without disrupting the use of those LEDs for simple illumination. You can dim the lights so that they no longer shine but the data transmission is uninterrupted. 10,000 times more bandwidth, infrastructure already in place. Energy savings. Smartphones usually have an LED flashlight function so they can be a transmitter too. Data through illumination! Of course, light doesn’t pass through walls so security is ensured. Applications are beyond imagination at the moment says Haas.
