Abstract

Systems and techniques for motion adaptive wireless user equipment (UE) in a wireless network are disclosed. These techniques can leverage kinetic information to select a preferred radio (or radio technology) or adapt a reselection scanning interval. This can serve to improve the performance of a UE by reducing the amount of power expended in maintaining an adequate level of connectedness to the wireless network components in the face of UE movement. In a further aspect, kinetic power generators can be employed as a source of UE transit data. Kinetic fingerprints can be compared to UE transit data, e.g., that acquired from a kinetic generator of the UE, to facilitate selection of preferred radios and reselection intervals. In this aspect, radio selection schema and reselection scanning schema can effectively be selected with little to no drain on a UE power source.
