Abstract: A base station is provided for communicating data to a mobile terminal unit by means of at least one antenna unit, wherein the at least one antenna unit is linked to the base station by means of at least one optical fiber and the at least one antenna unit is operable to communicate wirelessly with the mobile terminal unit. The base station comprises an optical transmitter for transmitting modulated data signals to the at least one antenna unit for wireless transmission, an optical receiver for receiving modulated data signals forwarded by the at least one antenna unit and a demodulator for demodulating received modulated data signals.

Abstract: An apparatus and method are provided for communicating data between a first and a second terminal unit, wherein at least one of the terminal units is a mobile terminal unit. The apparatus includes a base station and a number of antenna units each linked to the base station. The base station has a transmitter that transmits modulated data signals to each of the antenna units, a receiver that receives modulated data signals forwarded by at least one of the antenna units, demodulator that demodulates received modulated data signals that have been modulated according to a predetermined modulation scheme.
