摘要：
Provided is a wireless communication system in which a first wireless device and a second wireless device intermittently perform wireless communication, in which the first wireless device repeatedly transmits an activation signal for activating the second wireless device at a first cycle until receiving a response signal from the second wireless device, the second wireless device repeatedly executes detection processing of the activation signal at a second cycle that is longer than the first cycle, receives, when a part of the activation signal is detected in the detection processing, the activation signal, transmits, when the activation signal is addressed to the second wireless device itself, the response signal to the first wireless device, the first wireless device transmits, when the response signal is received, data to the second wireless device, and the second wireless device receives, after transmitting the response signal, the data from the first wireless device.
