Abstract
A wireless local area network client device scans for wireless local area networks using a scanning scheme that takes into account the relative prevalence, in a population of access points, of access point deployment on the channels to be scanned. In one aspect, channels on which more access points in the population are deployed are scanned prior to channels on which fewer access points in the population are deployed. In another aspect, channels on which more access points in the population are deployed are scanned more often than channels on which fewer access points in the population are deployed. In yet another aspect, channels on which more access points in the population are deployed are scanned prior to and more often than channels on which fewer access points in the population are deployed.
