PROBLEM TO BE SOLVED: To provide a radio repeater for relaying continuous data such as a moving image and sound without accompanying large time delay while maintaining real time. SOLUTION: The radio repeater includes a first radio transmitting and receiving means (1 to 5) for receiving a first information signal from first communication equipment for performing transmission by a first radio frequency, converting the information signal into one in a second radio frequency different from the first radio frequency and transmitting the information signal to second communication equipment for performing communication in the second radio frequency; and a second radio transmitting and receiving means (6 to 10) for receiving second information signal from the second communication equipment for performing transmission in the second radio frequency, converting the information signal into one in the first radio frequency and transmitting the information signal to the first communication equipment.
