Abstract:
1. A communication device comprising: a detection unit configured to detect a transmission path characteristic in communication with each of other communication devices; a determination unit configured to classify a communication device out of the other communication devices into a first group when the detected transmission path characteristic satisfies a predetermined criterion, and to classify a communication device out of the other communication devices into a second group when the detected transmission path characteristic does not satisfy the predetermined criterion; a control unit configured to select a frequency band used for communication with another communication device that is a communication destination, from among a first frequency band and a second frequency band higher than the first frequency band, based on whether the other communication device that is a communication destination is classified into the first group or into the second group, the first and second frequency bands being obtained by dividing an entire frequency band used for communication; and a communication unit configured to perform communication with the other communication device that is a communication destination using the selected frequency band, wherein the determination unit is configured to determine that the detected transmission path characteristic satisfies the predetermined criterion when the communication device out of the other communication devices is connected to a first breaker to which the communication device comprising the determination unit is connected, and to determine that the detected transmission path characteristic does not satisfy the predetermined criterion when the communication device out of the other communication devices is not connected to the first breaker.
