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).

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.
