ABSTRACT:
A wireless terminal mounted on a traveling apparatus memorizes operation data on the traveling apparatus, determines possibility of transmitting the operation data based on the electric field intensity of beacon, existence of operation data which has not been transmitted to a base station apparatus, an elapsed time after a switch of the mode (storage wait mode/delivery wait mode) of the wireless terminal, a planned storage date, and the like, and transmits a response to the beacon transmitted from the base station apparatus and operation data if the transmission is possible. When the transmission of the operation data has been completed, the wireless terminal is set to the delivery wait mode, and is switched to a state of waiting for delivery beacon transmitted from the base station apparatus to the wireless terminal waiting for delivery. When the delivery beacon is received, it is switched to the storage wait mode.
