LED Light networks have been under development for sometime, but the Fraunhofer Institute for Telecommunications, Heinrich Hertz Institute HHI in Berlin, Germany has now been pushing the technology to its limits and is hoping to create a 800Mbps WLAN using the LED light network technology.

Currently the optical WLAN co-opts white LEDs used for regular illumination to transmit data up to 100 Mbit/s, by flickering the LED’s more rapidly than the human eye can see. Devices are then fitted with a simple photo diode to receive the wireless connectivity, with each LED light providing around a 90 square foot range for connectivity.
