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.

A method for application-based radio access technology (RAT) switching is provided. The method can include engaging in data communication for the application over a connection to a first RAT and measuring a connection quality metric of the connection to the first RAT. The method can further include determining a threshold connection quality metric for an application. The threshold connection quality metric can be defined for the application and can be different from a second threshold connection quality metric defined for a second application. The method can also include comparing the measured connection quality metric to the threshold connection quality metric. The method can additionally include switching from the first RAT to a second RAT and engaging in data communication for the application over the second RAT in an instance in which the quality metric does not satisfy the threshold connection quality metric.

Application-based radio-access technology switching

A method for management of multiple radio links for a wireless peer-to-peer (P2P) session is disclosed. The method can include a wireless communication device providing interface address information for a first radio interface and a second radio interface implemented on the wireless communication device to a peer device when establishing a wireless P2P session with the peer device; establishing a threshold for transitioning between the first radio interface and the second radio interface during the wireless P2P session; determining during the wireless P2P session that the threshold has been met; and in response to the threshold being met, signaling to the peer device to transition to the second radio interface, and using the second radio interface to continue the wireless P2P session.

Management of multiple radio links for wireless peer-to-peer communication

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.

Transmitting beacon frames over a wireless data link

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.

Communicating latency-sensitive data over a wireless data link

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.

Predicting routes using wireless networks

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.
