Patent ID: 8223662

Claim:
A method of wireless communication, comprising: identifying a first wireless local area network and a second wireless local area network; concurrently associating a mobile device with the first wireless local area network on a first channel and the second wireless local area network on a second channel different from the first channel, wherein the first wireless local area network transmits a first beacon at a first beacon interval, and the second wireless local area network transmits a second beacon at a second beacon interval, wherein the second beacon interval is at least partially concurrent with the first beacon interval; concurrently operating the mobile device in power save mode on each of the first wireless local area network and the second wireless local area network to control transmission of downlink data over the first and the second wireless local area networks; and defining, by the mobile device, a first beacon listen interval for receiving the first beacon and a second beacon listen interval for receiving the second beacon, wherein the second beacon listen interval is different from the first beacon listen interval, wherein the first beacon listen interval is a first integer multiple of the first beacon interval and the second beacon listen interval is a second integer multiple of the second beacon interval such that at least one of the first beacons transmitted at the first beacon interval is outside of the first beacon listen interval and such that at least one of the second beacons transmitted at the second beacon interval is outside of the second beacon listen interval, and wherein the second integer multiple is different from the first integer multiple.
