Abstract: A method and apparatus are described for transmitting beacon frames to an electronic device over a wireless data. 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.

Abstract: A method and apparatus are described for communicating data frames over a wireless data link between an access point and a transceiver in an electronic device. In the described embodiments, a processing subsystem in the electronic device is configured to determine a frame interval based on a codec used to generate data contained in data frames. The transceiver is configured to use the frame interval as a timing reference for transitioning the transceiver between a constant awake mode and a power save mode so that during each of one or more frame intervals, the transceiver: transmits a data frame to the access point that indicates that the power save mode is disabled, enters the constant awake mode, receives one or more frames from the access point, transmits a frame to the access point that indicates that the power save mode is enabled, and enters the power save mode.

Abstract: A method and apparatus for wireless network selection by a wireless mobile device is disclosed. In one embodiment, network performance metrics related to the wireless networks to be considered can be evaluated. The network performance metrics can be weighted and a related ranking metric can be determined. The ranking metric can be used to select a wireless network. In one embodiment, network performance metrics can include a round trip time, which describes a round trip data transit time between the wireless mobile device to a particular network device, and a power metric describing the amount of power needed to transfer an amount of data.

Abstract: The disclosed implementations provide a system and method of predicting routes for mobile devices using wireless networks, including generating and sending content to a mobile device that is travelling on a predetermined route (e.g., a bus route determined by a transportation agency). The mobile device can scan for a wireless network that is installed on a vehicle travelling on a predetermined route. The system can predict which predetermined route the mobile device is travelling on by accessing a database that associates wireless networks with transportation vehicles. The system can confirm whether the mobile device is travelling on a predetermined route based on the device's sensor measurements, timestamps collected over a period of time and the identity of the wireless network that is connected to the device. The system can send content to the mobile device based on the mobile device's location and predicted future locations along the predetermined route.

Abstract: A method and apparatus for a wireless device that can adapt a rate of related wireless network unit scans for adjacent networks is disclosed. In one embodiment, the wireless device can include a wireless network unit and a co-located geo-location signal receiver, and a processor. The processor can determine the position and speed of the wireless device from data received from the geo-location signal receiver. The processor can configure the wireless network unit to adapt the rate of related wireless network scans based upon determined speed and position. In one embodiment, the wireless network unit scans can be wireless scans for other nearby networks for roaming or location based services.
