Active Mode - Default power management mode for most 802.11 stations. When a station is set for active mode, the wireless station is always ready to transmit or receive data. Active mode is sometimes referred to as Continuous aware mode, and it provides no battery conservation. In the MAC header of an 802.11 frame, the Power management field is 1 bit in length and is used to indicated the power-magagement mode of the station. A value of 0 indicated that the station is in active mode. Stations running in Active mode will achieve higher throughput than stations running in power save mode, but the battery life will typically be much shorter."
