Abstract
A wireless communication system using mimicked near field communication is disposed in a peripheral application device and configured to be connected with a mobile device. The system includes a wireless communication module configured to send a control command, and an RF switching circuit configured to be switched to a low or normal power mode according to the control command. Under the low power mode, a signal attenuation unit of the RF switching circuit attenuates a frequency of a transmission signal emitted from the wireless communication module to generate an output signal. Under the normal power mode, the signal attenuation unit maintains the frequency of the transmission signal. The signal frequency is allowed to be attenuated during an authentication phase to thereby achieve near field communication, and an original wireless transmission mechanism is allowed to be used after authentication is completed so as to perform operation of the peripheral application device.
