A system and method for operating a wireless telephone system, particularly a wireless Private Branch Exchange (Pbx), as both a voice system and a pager system. The system includes a protocol for communicating both voice conversations and display data to a remote unit. A digital communication system, in which is included a Time Domain Multiple Access system, operated with plural antenna to reduce the problems associated with fading, interference and multipath in signals received from mobile, wireless units. The protocol used between the fixed station and the mobile wireless units provides an opportunity for the fixed station to evaluate the signal received from the wireless unit and to transmit to the wireless unit using the antenna judged to have the best received signal.
