Abstract: The object is to provide a radio wave control system that is capable of suppressing radio wave interference. A radio wave control system according to the present disclosure includes a reflective plate (10) configured to reflect an undesired radio wave that causes interference for a communication apparatus, a control unit (21) that causes a reflected wave of the undesired radio wave to be transmitted in a direction in which the communication apparatus is present, and a communication unit (22) that receives interference information indicating an interference state in the communication apparatus, and the control unit (21) determines a phase of the reflected wave reaching the communication apparatus by using the interference information.
