Abstract: In a simulcast communication session, at least one condition is monitored that is indicative of the potential occurrence of time domain interference at a plurality of mobile subscriber units. In response to such monitoring at least one simulcast operating parameter (SOP) is dynamically modified to reduce time domain interference experienced by one or more of the mobile subscriber units. The SOP is modified to minimize time domain interference within at least a portion of an overlap area defined between a first base transceiver station and a second base transceiver station.

Abstract: The present invention provides increased geographical coverage and system capacity for mobile/portable radio transceivers using adjacent and typically separate radio communication frequency bands. A radio that transceives in just one frequency band is adapted to provide a configurable duplexing arrangement to permit communications in extended frequency bands. Duplexing circuitry is connected between the radio antenna and the radio transmitter and receiver. Depending upon the mode of operation of the radio transceiver, switches are selectively operated for variously configuring the antenna, duplexer circuitry, receiver, and transmitter to permit communications in a first or a second set of transmit/receive frequency bands. In one preferred example embodiment, only a single duplexer is employed connected to the antenna and transceiving circuitry through plural switches.
