Abstract:
One embodiment of the present invention provides a portable device, which is configured to join a known Wi-Fi network. While the device is not associated with a known access point, the device scans for access points at a scanning frequency wherein information about known access points has been stored in a database in the device. During this scanning process, the device determines whether the device is proximate to a known access point and the device sets the device's scanning frequency based on whether the device is proximate to a known access point.
