A system and method for energy conservation in wireless networks (1) includes techniques for powering down a Soft AP device (103) while still maintaining compliance with the "always on" requirement for access points in wireless networks. The system and method includes a technique for causing a host system (100) having a Soft AP device integrated therein to go into a low power, or energy conservation mode when no wireless activity has occurred over a predetermined period, and for monitoring to identify appropriate signals even while in the low power mode. If an appropriate signal is detected, a wake up signal is generated and the host system (100), including the Soft AP (103) device, is returned to normal functionality.

Cette invention concerne un système et procédé visant à économiser l'énergie dans un réseau sans fil, qui fait intervenir des techniques de désactivation d'un point d'accès à base de logiciel (Soft AP) tout en respectant l'exigence d'éveil permanent pour les points d'accès du réseau sans fil. Ce système et ce procédé font appel à une technique permettant de faire passer un système hôte, dans lequel est intégré un dispositif Soft AP, en mode basse puissance, ou de conservation d'énergie, lorsqu'aucune activité sans fil n'est s'est produite au cours d'un laps de temps prédéterminé, et à exercer une surveillance visant à identifier des signaux appropriés même en mode basse puissance. En cas de détection d'un signal approprié, un signal d'activation est produit et le système hôte, y compris le dispositif Soft AP, réintègre a fonction normale.
