Abstract:
1. A client station comprising: a transceiver module configured to transmit and receive data via a frequency band, wherein the frequency band includes a plurality of channels; a scanning module configured to an association module configured to, in response to the scanning module determining that one or more access points are available for association, determine whether to associate with one of the one or more access points determined to be available for association; a preamble detection module configured to detect whether a preamble of a frame is received via a first channel of the multiple channels; and a decoding module configured to attempt to decode a signal field of the frame in response to the preamble detection module detecting that the preamble of the frame is received via the first channel of the multiple channels, wherein the signal field follows the preamble, wherein the decoding module is configured to stop decoding the signal field in response to the decoding module (i) being unable to decode the signal field, or (ii) determining, based on the decoding of the signal field, that the frame is neither a beacon nor a probe response to a probe request; and wherein the preamble detection module is configured to, in response to the decoding module stopping the decoding of the signal field, begin detecting whether a second preamble of a second frame is received via a second channel of the multiple channels.
