WIRELESS COMMUNICATION SYSTEM USING MIMICKED NEAR FIELD COMMUNICATION AND AUTHENTICATION METHOD THEREOF
First Claim
1. A wireless communication system using mimicked near field communication, wherein the wireless communication system is disposed in a peripheral application device and configured to be connected with a mobile device, the wireless communication system comprising:
- a wireless communication module configured to send a control command; and
an RF switching circuit connected to the wireless communication module and configured to be switched to a low power mode or a normal power mode according to the control command,wherein the RF switching circuit comprises a signal attenuation unit that attenuates a frequency of a transmission signal emitted from the wireless communication module when the RF switching circuit is switched to the low power mode and generates an output signal, and maintains the frequency of the transmission signal when the RF switching circuit is switched to the normal power mode.

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.
