COMMUNICATION DEVICE AND WATT-HOUR METER

PROBLEM TO BE SOLVED: To ensure reliability of communication, reduce power consumption, and suppress increase in device cost and size in a communications device performing one or both of communication by radio and communication by power lines. SOLUTION: A communications device 10 acquires a measured value (meter-reading value) of an electrical energy measuring unit 4 and uses one or both of a power-line communication unit 200 and a radio communication unit 300, to transmit the measurement value to a center device 30 via a base station 20. A baseband processing unit 100 generates the measured value acquired from the electrical energy measuring unit 4 as a baseband signal common to the power-line communication unit 200 and the radio communication unit 300. Also, selection for the use of one or both of communications by power lines and communication by radio is executed by turning on and off a first SW11 and a second SW12. COPYRIGHT: (C)2011,JPO&INPIT
