Energy saving design for wireless communication device

The present invention relates to a wireless communication device, which comprises a processor; a control switch electrically coupled with the processor; and a wireless communication module electrically coupled with the control switch in which the processor may control the control switch to make an off state, so that the wireless communication module may be turned to a non-powered state. Furthermore, the processor may also control the control switch to switch from the off state to an on state, so that the wireless communication module may execute the information reception and transmission. The power control method of the wireless communication device is that the processor sends out a first control signal to a control switch and the control switch is switched to the off state, so that the wireless communication module may be turned to the non-powered state; and the processor sends out a second control signal to the control switch and the control switch is switched to the on state, so that the wireless communica
