Abstract:
This communication device is mounted to a smart meter and comprises a secondary battery, a transceiver circuit capable of operating using power supplied from the secondary battery, and an antenna whereby a wireless signal based on a transmission signal output from the transceiver circuit is emitted into a space. When power supplied to the smart meter from the exterior is cut off, the transceiver circuit outputs the transmission signal, which represents a predetermined alarm, to the antenna using power supplied from the secondary battery and thereby wirelessly transmits the alarm via the antenna.
