ABSTRACT:
A mobile device (110) and combined method (400/500) for frequency hopping is provided. The frequency hopping can combine a receive scanning (400) with a scanning (500) for a transmit frequency for providing automated channel selection. The transmit scanning can include determining whether a push to talk (PTT) is pressed (501), and selecting a transmit frequency from a set of frequency channels (130) based on a measured activity (150) on the set of frequencies. If the PTT (240) is within the hang-time (504), a frequency that is currently active during the hangtime can be selected, else, a frequency having a lowest activity count (506) can be selected for transmitting a communication in response to the PTT.
