ABSTRACT:
In cellular radio networks with TDMA transmission, the maximum signal propagation time inside a radio cell limits its propagation to a maximum radius, e.g. to 35 km in the known GSM. To extend the radio cell, the invention provides a fixed base station (BTS) with a TDMA radio receiver (RX) and an additional TDMA radio receiver (RXe), which receives lagging TDMA radio pulses from mobile stations (MS3) that are positioned outside of the radio cells (C). In this way, the fixed base station (BTS) supplies an extended radio cell (Ce), in which however only the maximum signal propagation time corresponding to the maximum expansion of the (small) radio cell (C) requires compensation.
