A reconfigurable wireless transceiver and method of use are disclosed. As one example, a reconfigurable wireless transceiver is disclosed, which includes a transmitter unit, a plurality of receiver units, and a processing unit coupled to the plurality of receiver units. A first receiver unit of the plurality of receiver units receives a first signal at a first frequency, and determines a strength level of the first signal. A second receiver unit of the plurality of receiver units searches for a second signal at a second frequency, detects the second signal at the second frequency, and determines a strength level of the detected second signal. The processing unit determines if the strength level of the detected second signal is greater than a predetermined value, and enables the second receiver unit to receive a third signal at substantially the second frequency, if the strength level of the detected second signal is greater than the predetermined value. The predetermined value may be substantially equal to the signal strength of the received first signal, and the third signal may be associated with over-the-air programming or tasking. As a second example, a method for reconfiguring a wireless transceiver is disclosed, which includes receiving a first signal in a first frequency band, determining a signal strength of the received signal, searching for a second signal in a second frequency band, detecting the second signal, determining a signal strength of the detected second signal, comparing the signal strength of the received first signal with a predetermined signal strength value, and enabling reception of the detected second signal and disabling reception of the first signal, if the signal strength of the detected second signal is greater than the predetermined signal strength value.
