ABSTRACT:
A wireless communication system includes a portable communication unit (PCU) (120) and a plurality of fixed communication units (FCUs) (102) covering a plurality of radio coverage areas (108, 110, 112). The FCUs are coupled to a telephone system (114) by telephone lines (116) shared in common by the FCUs (102). The PCU (120) is associated with one of the telephone lines (116) for receiving an incoming call. THE FCUs (102) are coupled to the telephone line (116) in response to an incoming call, and signals are transmitted from the FCUs (102) to establish a wireless link with the called PCU (120). When one of the FCUs (102) receives a response from the called PCU (120), the receiving FCU (102) establishes the wireless link and the rest of the FCUs (102) stop further signal transmissions.
