WIRELESS LOCAL AREA NETWORK CHANNEL SCANNING
First Claim
1. A mobile device capable of communication with wireless access points over a plurality of wireless local area network (WLAN) channels including prevailing channels corresponding to a region and non-prevailing channels corresponding to the region, the mobile device comprising:
- a scanning module configured to passively scan each channel of a subset of channels for a beacon signal; and
a control module communicatively coupled to the scanning module and configured to control which channels the scanning module passively scans such that the subset of channels comprises multiple channels of the plurality of WLAN channels but less than all of the plurality of WLAN channels, and such that the subset of channels includes at least one of the prevailing channels.
