CONCENTRATED SUBSCRIBER SYSTEM FOR WIRELESS LOCAL LOOP.

摘要

A cellular telephone concentrated subscriber system (113) is described. The concentrated subscriber system includes a set of subscriber units (116) each having a unique electronic serial number that is coupled to a concentrated subscriber system controller that provides a radio frequency (RF) interface to the standard base station transceiver (110) of a cellular telephone system. The concentrated subscriber system controller includes a set of modulator-demodulator systems (modems) and a RF transceiver and antenna system (270, 250) 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 (254) for coupling the set of subscriber unit (116) to the set of modems via a multiplexed (266) system using stored information. In the preferred embodiment the number of modems is significantly less than the number of subscriber units which are implemented in a simplified manner so that the per user cost of cellular telephone service is reduced.
