Abstract
Emergence of white-light LEDs allows the combination of lighting and
information broadcast functionality in one optical source. We investigate
analytically and by Monte Carlo simulations feasible 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 baseband [i.e., pulse-amplitude modulation
(PAM)] and discrete multitone (DMT) transmission show that data rates of more
than 100 Mbit/s can be expected despite the rather low bandwidth of the system.
