Reportedly, networking researchers come from the Fraunhofer Institute for Telecommunications, Heinrich Hertz Institute HHI in Berlin, Germany, have used LED lighting to distribute Full HD movies to notebooks, smartphones and other devices, in a system that could join WiFi and PowerLine networks in shuttling high-speed data around the home and office.
The optical WLAN co-opts white LEDs used for regular illumination to transmit data at up to 100 Mbit/s, by flickering it more rapidly than the human eye can see.
