An objective of the present invention is to implement a field wireless relay device whereby it is possible to further extend battery life. Provided is a field wireless relay device, configured to operate with a battery, comprising a communication relay unit which further comprises a receiving-transmission function which re-amplifies a received signal of a wireless communication which is carried out between a transmitting station and a receiving station via an antenna and transmits said signal and a routing function which designates a communication path of the wireless communication. An antenna control unit which controls a connected antenna assembly, and an antenna control determination unit which determines a type of control which the antenna control unit is to carry out based on the signal strength of a received signal to be relayed, are disposed upon the field wireless relay device. |
