Abstract
A power supply control apparatus is applied to a communication apparatus that is applied to a mobile apparatus. The power supply control apparatus includes a switch, coupled between the communication apparatus and a power supply; and a signal detecting unit, for detecting a wireless signal via an electromagnetic introduction approach to correspondingly generate a detection signal. It is determined whether to provide power to the communication apparatus via the switch according to the detection signal.
