Abstract
Described herein is an implementation that reduces the battery consumption of an energy-constrained computing device that is capable of communicating over a wireless network. As conditions and circumstances warrant, the implementation selects one of multiple radios (e.g., two)—with each having a unique combination of characteristics (in terms of power-consumption, data-rate, range and/or frequency band of operation) for wireless communications to and from a wireless device. The implementation selects one radio to minimize power-consumption while maintaining effective wireless data communication. This abstract itself is not intended to limit the scope of this patent. The scope of the present invention is pointed out in the appending claims.
