beacons are sent out at the lowest "basic rate", typically 1-2Mbps. STAs on adjacent channels can potentially decode the beacon if the SNR is 'high enough'.
There is also a queing/layering issue as to when the channel is changed on the station and when the scan went out, so the channel number (which is the frequency) is needed to know what happened.
