Abstract
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.
