Abrégé
(EN)
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, rang 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.

L'invention concerne une application qui réduit la consommation électrique dans un dispositif de calcul à contrainte énergétique, apte à communiquer dans un réseau sans fil. Comme garantie des conditions nécessaires, cette application sélectionne une radio parmi plusieurs radios (par exemple deux), lesquelles ont une combinaison unique de caractéristiques (en termes de consommation de courant, de débit de sortie de données, de plage opérationnelle et/ou de bande de fréquence) pour des communications sans fil vers des dispositifs sans fil et à partir de ceux-ci. L'application sélectionne une radio pour minimiser la consommation énergétique tout en maintenant la communication de données sans fil. Ce résumé ne se limite pas au domaine d'application de ce brevet. Le domaine d'application de la présente invention est indiqué dans les revendications annexes.
