| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a wireless communication system in which a judgment can be made whether a signal such as a video signal cannot be received normally by radio because of jamming between other apparatus in the working frequency band of wireless communication or not without using a dedicated apparatus. SOLUTION: The wireless communication system comprises a wireless communication means 11 performing wireless communication between wireless communication apparatus by using one of a plurality of occupied frequency bands in a predetermined working frequency band. The wireless communication system further comprises a communication means 12 for detection performing wireless communication in a occupied frequency band for detecting jamming which is shifted from the occupied frequency band at the end of the predetermined working frequency band by a predetermined frequency reversely to the predetermined working frequency band side, and a means 22 for detecting jamming by communicating through the communication means 12 for detection.
