Zusammenfassung:The present invention relates to a communication mode identification method. Particularly, the communication mode identification method includes analyzing a received signal generated in an ISM band to determine whether a specific channel is currently being used or a WS channel, and determining whether the radio signal of an active channel indicates an OFDM signal or a Bluetooth signal. After that, the communication mode identification method includes identifying a communication mode by using the frequency component of the radio signal when the determined radio signal is the OFDM signal. So, it is possible to identify WLAN, Bluetooth and white space used in a particular band of 2.4 GHz and 5 GHz. 본 발명은 통신 방식 식별 방법에 관한 것이다. 구체적으로, 통신 방식 식별 방법은 ISM 대역에서 발생하는 수신 신호를 분석하여 현재 특정 채널이 사용 중인지 또는 WS 채널인지 판단하고, 사용 중인 채널의 무선 신호가 OFDM 신호, 블루투스 신호 중 어느 신호를 나타내는지 판단한다. 이후, 통신 방식 식별 방법은 판단된 무선 신호가 OFDM 신호인 경우, 상기 무선 신호의 주파수 성분을 이용해 통신 방식을 식별하는 방법에 관한 것이다.
