The present invention relates to a short range communication device performing multiplex transmission of asynchronous wireless signals. The short range communication device performing multiplex transmission of the asynchronous wireless signals according to the present invention comprises: a power supply unit receiving an external power source; a power transforming unit transforming the external power source into a set power source; a power charging unit charging a charging power source via the transformed power source; and a chip module including a signal transmission unit transmitting the asynchronous wireless signal without specifying a separate reception side and a transmission control unit controlling multiplex transmission of asynchronous wireless signals with low output signal strength and asynchronous wireless signals with high output signal strength amplified to set signal strength when the asynchronous wireless signals are transmitted using the external power source. The present invention automatically determines position relationship between a user and the short range communication device.

    본 발명은 비동기 무선신호를 다중 송출하는 근거리장치에 관한 것으로, 본 발명에 따른 비동기 무선신호를 다중 송출하는 근거리장치는, 와이파이 통신을 제공하는 근거리장치에 있어서, 외부 전원을 공급받는 전원 공급부와 상기 외부 전원을 지정된 전원으로 변환하는 전원 변환부 및 상기 변환된 전원을 통해 충전 전원을 충전하는 전원 충전부를 구비하며, 별도의 수신 측을 특정하지 않고 비동기 무선신호를 송출하는 신호 송출부와, 상기 외부 전원을 이용하여 비동기 무선신호를 송출 시 저출력 신호강도의 비동기 무선신호와 지정된 신호강도로 증폭된 고출력 신호강도의 비동기 무선신호를 다중 송출하도록 제어하는 송출 제어부를 구비한 칩모듈을 구비한다.
