1. A method for detecting the presence of a signal on one of at least two frequency channels in a frequency translating repeater for use in wireless local area network (WLAN) operating according to a protocol, the method comprising:

  • establishing a first threshold associated with a first of the at least two frequency channels and a second threshold associated with a second of the at least two frequency channels;

    monitoring the first and second frequency channels to detect the signal thereon in accordance with a first detection mode including the first threshold and the second threshold; and

    qualifying, when the signal is detected, to determine whether the detected signal is a wanted signal or an unwanted signal, wherein the qualifying further comprisesmeasuring an elapsed time associated with the detected signal, if the detected signal is the wanted signal;

    refining at least one of a first or a second criteria based upon a threshold event, wherein the first criteria is refined if the threshold event is the elapsed time being greater than a minimum value and the second criteria is refined if the threshold event is the elapsed time being not greater than the minimum value.
