Abstract: An apparatus and methods are provided for automatically detecting and connecting to a Wi-Fi network. In these methods, a wireless device listens for beacons that are sent using a low-power wireless protocol. Once the wireless device detects a first beacon at a first location, the wireless device extracts a first beacon region identifier from the beacon and correlates the first beacon region identifier with a first Wi-Fi network that is located at the first location. Next, the wireless device retrieves a first set of credentials for connecting to the first Wi-Fi network. Once the first set of credentials is retrieved, the wireless device uses the first set of credentials to connect to the first Wi-Fi network.

Abstract: A wireless device may automatically connect to a preferred wireless network, such as a preferred Wi-Fi network. The wireless device may order a plurality of wireless networks according to initial criteria, such as the time the wireless device last connected to each wireless network. Preference rules may then be applied to reorder the wireless networks. Each preference rule may be applied only if an associated score meets a threshold. A scan may be performed to determine which of the wireless networks are available for connection. The wireless device may automatically connect to the highest-ordered available wireless network. The scores associated with the preference rules may be modified in response to events that indicate a user preference for one or more of the wireless networks, such as manually switching from one network to another.

Abstract: Wi-Fi link health monitoring by a wireless device. Signal strength (e.g., RSSI) of a Wi-Fi link may be monitored. If the signal strength is low, further link quality metrics may be monitored. If it is determined that health of the Wi-Fi link is poor based on monitoring signal strength and other link quality metrics, roaming to a different Wi-Fi network may be performed, the Wi-Fi link may be disconnected, and/or an application processor of the wireless device may be woken.

Abstract: Methods and apparatus for location-based control of parameters such as radio frequency (RF) transmission characteristics of a wireless device. In one embodiment, a determination of a maximum allowable level for a given characteristic associated with the location of the wireless device is made, and the transmission characteristic of the wireless device is adjusted based at least in part on this maximum allowable level. The location may correspond to a regulatory domain with specific requirements for wireless transmitters. A database is referenced to retrieve these requirements. The maximum allowable levels are derived from the requirements. Thus, exemplary wireless devices are capable of universal regulatory compliance.

Abstract: A method and system are described for determining parameters of an access point (AP). In the described embodiments, during a first time period, a portable electronic device (PED) scans for APs on a wireless local area network (WLAN) channel. Then, when an AP is detected on the WLAN channel, the PED determines if the AP includes a general advertisement service (GAS) protocol to make available information related to services provided by the AP. If the AP includes the GAS protocol, then the PED transmits a GAS request frame to the AP. If a response to the GAS request frame is not received from the AP within the first time period, then the PED extends the dwell time to wait for the response for a second time period, wherein a duration of the second time period is determined based on a total allowable time to scan for APs.

Abstract: An electronic device connects to a network associated with a service provider via a router at a home location. During a time interval, the electronic device provides information specifying a network address of the router to an authentication computer when the electronic device is connected to a network. The authentication computer uses the received information to determine a connection pattern of the electronic device. Moreover, the authentication computer identifies that the electronic device is at the home location based on the connection pattern. Then, the authentication computer provides, to an accounting computer associated with the service provider, a request to allow the electronic device to access a wireless network associated with the service provider at a remote location (which is other than the home location). Furthermore, the authentication computer communicates network information to the electronic device, which allows the electronic device to access the wireless network without providing authentication information.

Abstract: An electronic device, e.g., a mobile device, having access to a wireless network roams from one access point (AP) to another using access point detection based on location and learning. A learning scheme may modify a list of nearby access points determined based on location to identify neighboring access points where roaming is possible. The identified neighboring access points where roaming is possible may be ordered based on roaming history, such as the frequency of the roams to a particular AP. The roaming history may be maintained on a per client basis or aggregated across all clients using an AP.

Abstract: In order to facilitate reduced power consumption of an electronic device (such as a smartphone) when communicating with another electronic device (such as an access point) in a wireless network, the electronic device may change a frequency of network scans performed by an interface circuit in the electronic device based on a motion profile of the electronic device. In particular, the electronic device may determine the motion profile based on spatial information, such as: acceleration data, orientation data, Global Positioning System data and/or data from the wireless network. Then, the electronic device may change the frequency of the network scans performed by the interface circuit based on the motion profile. In this way, the frequency of the network scans can be reduced when the electronic device is stationary or moving rapidly (such as when a user of the electronic device is driving in a car).
