  • Publication number: 20240147296
    Abstract: Provided is an interference control system for wireless communication suitable for limiting the total amount of interference to which an interfered-with wireless communicator to be protected is subjected by interfering wireless communicators. A repeater disposed between the interfering wireless communicator and a controller includes a processor and a memory storing a program executed by the processor. The processor acquires registration information including a position and a transmission power for each interfering wireless communicator, and estimates, for each interfering wireless communicator, a terminal range in which there is a likelihood that a terminal wireless communicator communicating with the interfering wireless communicator is present based on the position and the transmission power. The processor transmits a registration application including the terminal range to the control device.
