Method for optimizing power consumption in wireless devices using data rate efficiency factor

摘要

An electronic device has wireless communications circuitry that supports communications using multiple radio access technologies. The electronic device may gather information such as data rate values, power consumption values, and other data for a currently active radio access technology and an alternative radio access technology. The electronic device may automatically switch between the currently active radio access technology and the alternative radio access technology based on a value of a data rate efficiency metric. The data rate efficiency metric may represent how efficiently each radio access technology is capable of using power to convey a given amount of data per unit time. The data rate efficiency metric may be evaluated using measured power consumption data, measured data rate values, and operating parameters such as signal strength and transmitted power parameters.
