Emergence of white-light LEDs allows synergy of lighting and broadcast/communication function in one optical source. We investigate possible data transmission rates in a moderate-size office room where we assume illumination conforming to standards and the use of commercially available LEDs and photodiodes. The performances of systems relying on base-band and DMT transmission show that data rates of more than 100 Mbit/s can be expected despite the rather low bandwidth of the system.
