  • Transmitting beacon frames over a wireless data link
    Patent number: 9510280
    Abstract: A method and apparatus are described for transmitting beacon frames from an access point to an electronic device over a wireless data link. In the described embodiments, a processing subsystem is coupled to a transceiver and is configured to determine a beacon frame interval based on a highest common factor of a listen interval for the electronic device and a delivery traffic indication message interval, and to control the transceiver to transmit a beacon frame each beacon frame interval.

  • Using proximate access points to ensure fast Wi-Fi network discovery and reconnection with reduced power consumption
    Patent number: 9408140
    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.
