摘要:
A cellular telephone concentrated subscriber system is described. The concentrated subscriber system includes a set of subscriber units coupled to a concentrated subscriber system controller. The concentrated subscriber system controller that provides a radio frequency (RF) interface to the standard base station transceiver of a cellular telephone system. Each subscriber unit has a unique electronic serial number. The concentrated subscriber system controller includes a set of modulator-demodulator systems (modems) and a RF transceiver and antenna system that is configured to transmit sufficient information to conduct multiple telephone calls over both long and short distances. The concentrated subscriber system controller also includes control circuitry for coupling the set of subscriber unit to the set of modems via a multiplexed system using stored information. In the preferred embodiment the number of modems is significantly less the number of subscriber units which are implemented in a simplified manner so that the per user cost of cellular telephone service is reduced.
