Abstract: Provided is a device that executes a process of guaranteeing protection for a protection system in a case where a communication device itself, such as an access point, that executes wireless communication determines a frequency or the like used for the wireless communication. According to an aspect of the present disclosure, a communication system includes a plurality of communication devices configured to execute wireless communication using a frequency of a specific frequency band; and an information processing device configured to record information regarding interference of the plurality of communication devices with a protection system in the specific frequency band. The communication device executes single interference estimation on the protection system before executing the wireless communication to estimate interference of the wireless communication with the protection system. In addition, the communication device executes the wireless communication in a case where a sum of aggregated interference of the plurality of communication devices with the protection system before executing the single interference estimation obtained from the information and interference estimated by executing the single interference estimation does not exceed a limit value of interference with the protection system.
