Abstract
An apparatus (304) for scanning among a plurality of channels in a radio communication system (300) includes receive circuitry (310) and control circuitry (312). The receive circuitry (310) is capable of being tuned to any one of the plurality of channels and measures reception strength of the tuned channel. The control circuitry (312) controls the receive circuitry (310) to scan through all of the plurality of channels one at a time. The control circuitry (312) stores a first reading of a measured reception strength of the tuned channel before powering off the receive circuitry (310). The control circuitry (312) stores a second reading of a measured reception strength of the tuned channel after powering the receive circuitry (310) back on.
