    <subfield code="a">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 moderatesize
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
(i.e. Pulse-Amplitude Modulation -PAM) and discrete multi-tone
(DMT) transmission show that data rates of more than
100 Mbit/s can be expected despite the rather low bandwidth of
the system.</subfield>
