Described is a system and method for power conservation in a wireless device. The method includes switching, by a wireless computing unit, from a first communication mode to a second communication mode at a predefined time interval. The unit receives wireless signals only when in the second communication mode, and the first communication mode is a power-save mode. The unit then receives a wireless signal, and initiates a wireless connection to a wireless arrangement to obtain traffic data from the wireless arrangement when the signal includes a traffic data indicator which is indicative of existence of the traffic data. The unit switches into the first communication mode when the indicator is absent from the signal.

L'invention concerne un système et un procédé destinés à la conservation d'énergie dans un dispositif sans fil. Le procédé inclut une commutation, grâce à une unité de calcul sans fil, à partir d'un premier mode de communication vers un second mode de communication à un intervalle de temps prédéfini. L'unité ne reçoit des signaux sans fil que lorsqu'elle se trouve dans le second mode de communication, et le premier mode de communication est un mode d'économie d'énergie. L'unité reçoit ensuite un signal sans fil et déclenche une connexion sans fil vers un agencement sans fil afin d'obtenir des données de trafic en provenance de l'agencement sans fil lorsque le signal inclut un indicateur de données de trafic qui est indicatif de l'existence des données de trafic. L'unité bascule dans le premier mode de communication lorsque l'indicateur est absent du signal.
