Abstract:
1. A method for selecting a frequency band of operation of a plurality of frequency ranges supported by a Wireless Local Area Network (WLAN) device, the method comprising: for each of the plurality of frequency ranges supported by the WLAN device, determining, by a processor, a plurality of quality indicators based at least in part on probe responses; determining, by the processor, a composite metric for each of the plurality of frequency ranges that includes at least two of the plurality of quality indicators; and based upon a comparison of the composite metric of at least two of the plurality of frequency ranges, selecting, by the processor, at least one of another frequency range as the frequency band of operation or another channel of the frequency band of operation for subsequent wireless communication, the at least one of another frequency range being selected from a frequency band rank table, the at least one of another frequency range supporting a maximum physical-layer rate as against unselected ones of the plurality of frequency ranges.
