摘要： A wireless communication system includes a first wireless communication device and a second wireless communication device that wirelessly communicates with the first wireless communication device. One of the first and second wireless communication devices is disposed in a mobile object, and the other is fixed. The first wireless communication device includes a wireless transmission/reception unit that transmits data to the second wireless communication device and performs wireless transmission and reception in order to detect whether the mobile object is stopped. When, in a first mode for transmitting data to the second wireless communication device and determining whether the reception strength of a received signal is equal to or greater than a first value, the first wireless communication device detects that the reception strength is equal to or greater than the first value, the first wireless communication device stops the transmission of data to the second wireless communication device, exits the first mode, and transitions to a second mode for determining whether the mobile object is stopped. Upon detecting in the second mode that the mobile object is stopped, the first wireless communication device exits the second mode and transmits data to the second wireless communication device.
