Fraunhofer-Verbund Mikroelektronik: Data from an LED ceiling light

Commercially available light-emitting diodes (LEDs) can do more than just generate light. Researchers at the Fraunhofer Heinrich Hertz Institute HHI have succeeded in transmitting broadband data streams within visible light via LED lamps to computers or other end devices that can receive data. ???Visible light communication??? is the name of this new transmission technology
