Abstract
A first radio receives, via a land mobile radio (LMR) radio frequency transceiver, a first transmission of an LMR call from a source transmitting radio transmitted on a first LMR frequency for re-transmission to one or more destination radios. The first radio measures a first measured signal level of the first transmission and receives, via a first short-range RF transceiver from a second radio, a second measured signal level of the first transmission as measured by the second radio. The first radio compares the first measured signal level and the second measured signal level and determines, based on the comparing, how the LMR call should be routed from the source transmitting radio to the one or more destination radios via the first and second radios. The first radio then transmits, via the first short-range RF transceiver, a corresponding instruction indicating a result of the determining to the second radio.
