Abstract:
1. An apparatus, operable to communicate data between a first and a second terminal unit, wherein at least one of said first and second terminal units is a mobile terminal unit, the apparatus comprising: a base station; and a plurality of antenna units having different areas of coverage, wherein each antenna unit is linked to said base station and is operable to transmit, wirelessly, modulated data signals received from said base station, and to forward modulated data signals, received wirelessly, to said base station, wherein said base station comprises: a transmitter for transmitting modulated data signals to each of said plurality of antenna units for wireless transmission using a single frequency band of a given data channel; a receiver for receiving modulated data signals forwarded by at least one of said plurality of antenna units at the single frequency band of said given data channel; and a demodulator for demodulating received modulated data signals in respect of said given data channel that have been modulated according to a predetermined modulation scheme, whereby, according to said predetermined scheme, successive blocks of modulated data in said data channel are arranged such that a predetermined minimum time period elapses between the arrival, at the receiver, of a first and the arrival of a second of said successive modulated data blocks and wherein, for a given arrangement of said plurality of antenna units, said predetermined minimum time period is set to correspond to a time interval at said receiver from the time of first arrival to the time of latest arrival of the first of said successive modulated data blocks in said data channel by means of antenna units in said given arrangement such that all data in a given data channel is communicated via at least one of the plurality of antenna units at one time.
