1. A communication repeater, comprising:
- a transmitting and receiving unit configured to transmit and receive a communication signal to/from a communication device with wireless communication;
a modem unit for modulating and demodulating the communication signal to a power line;
a power supply unit connected to a power line of a commercial power supply;
a power-line carrier communication unit configured to transmit and receive a communication signal superimposed on a carrier transmitted over the power line from/to the communication device;
a traffic detection unit configured to detect an amount of traffic of the power-line carrier communication; and
a control unit configured to control wireless communication of the transmitting and receiving unit with the communication device and power-line carrier communication of the power-line carrier communication unit with the communication device, whereinthe control unit, when the amount of traffic detected by the traffic detection unit exceeds a preset threshold, performs the wireless communication of the transmitting and receiving unit with the communication device.
