ADJUSTING COMMUNICATION STRATEGY FOR RADIO COMMUNICATIONS LOCATION

摘要

An acknowledge back portable selective call radio (10) for use in a selective call signal radio system (100) and method for determining selective call radio location (200-300), wherein the selective call radio (10) comprises a transceiver (14) for receiving selective call signals and transmitting acknowledge back signals, a processor (24) for monitoring and processing received selective calls signals to monitor errors in the selective call signal, a global positioning system receiver (12) activated by the processor (24) when the number of errors exceeds a predetermined threshold, wherein the global positioning system receiver (12) receives satellite transmitted signals for triangulating the position of the selective call radio (10), and wherein the geographic location determined by the processor (24) is transmitted in the acknowledge back signal to the selective call signal transceiver station (110) where a transmission strategy is selected in accordance with the location of the selective call radio (10).
