Abstract:
1. A wireless communication apparatus adapted for communication between a host and a communication device, the wireless communication apparatus comprising: a host transmission interface adapted to be coupled to the host; a host transmission interface controller coupled to the host transmission interface; a wireless transmission interface adapted for communicating with the communication device so as to receive packet data therefrom; a wireless transmission interface controller coupled to the wireless transmission interface; and a processor coupled between the host transmission interface controller and the wireless transmission interface controller, and operable to control a power state of the host transmission interface controller to enter a power consuming mode selected from a plurality of power consuming modes in accordance with a traffic volume and a plurality of traffic thresholds; wherein the processor is operable to control the power state of the host transmission interface controller to enter a deep low power consuming mode when the traffic volume is smaller than a first threshold value, a fast wake-up mode when the traffic volume is not smaller than the first threshold value and is smaller than a second threshold value larger than the first threshold value, and an active mode when the traffic volume is greater than the second threshold value.
