5. An interference control signal management device configured to cause an interference control signal transmitter to transmit an interference control signal that causes an interfering communication device to wait for transmission, the interfering communication device being present around a base station device and a terminal device that perform wireless local area network (LAN) communication and interfering with the wireless LAN communication, the interference control signal management device comprising:
a wireless environment information collecting unit configured to collect wireless environment information from the base station device and the interference control signal transmitter;
a protection target setting unit configured to set the wireless LAN communication between the base station device that is to be protected and the terminal device that is to be protected as protected communication based on the wireless environment information and determine the interference control signal transmitter around the interfering communication device that interferes with the protected communication; and
a control unit configured to cause the interference control signal transmitter that is determined to transmit the interference control signal that causes the interfering communication device to wait for transmission,
wherein the control unit instructs the interference control signal transmitter to start transmitting the interference control signal when detecting a start of the protected communication and instructs the interference control signal transmitter to stop transmitting the interference control signal when detecting a stop of the protected communication.
