A communication device includes a transmission path state determination unit; a communication unit and a topology determination unit configured to classify a destination device into a first group when a detected transmission path characteristic satisfies a criteria, and to classify a destination device into a second group when the detected transmission path characteristic does not satisfy the criteria. Additionally, a frequency band control unit is configured to select a first frequency band and a second frequency band higher than the first frequency band based on whether the destination device 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.
