Abstract

A radio communication system includes: slave devices which repetitively transmit, a plurality of times, a radio signal with a prescribed frequency that includes device identification information during a radio communication with a master device; a master device which generates communication situation information including a reception success rate and received signal strength of a radio signal during each radio communication from each slave device; and a failure factor estimation apparatus which, based on communication situation information with respect to a plurality of radio communications including a radio communication in which a communication failure of the received signal strength is lower than prescribed strength and/or the reception success rate is lower than a prescribed rate has occurred, generates and outputs failure factor presentation information indicating a failure inducer estimated to have induced the communication failure and an estimation result of a position of the failure inducer.
