Abstract
The invention relates to a low power module, and in particular, to a low power module applied in a station of a wireless communication system. A low power module includes a first MAC module, a second MAC module, a low power switch register, a control register unit, a slow clock generator, and a multiplexer (MUX). The first and second MAC module transmits and receives packets in a normal operational mode and a power save mode, respectively. The low power switch register switches a current mode to another mode. The control register unit controls the RF/BB module and the clock generator under the control of the low power switch register. The slow clock generator generates a slow operational clock for the second MAC module in the power save mode. The MUX chooses the normal operational or the slow operational clock periodically as a clock of the second MAC module according to the control register unit.
