Abstract
Techniques are provided for reducing power consumption in wireless communication devices. During an idle listening period, the clock rate of the receiver in the device is reduced. Data packets received by the receiver are then sampled at the reduced clock rate. A determination is made as to whether the data packet is intended for the device. The clock rate is restored to the full clock rate when the data packet is intended for the device. On the other hand, the receiver continues to operate at the reduced clock rate when the data packet is not intended for the device.
