| Zusammenfassung: | A radio relay device includes: an antenna, which transmits and receives a radio signal with respect to a counterpart radio relay device; and a directivity controller, which adjusts directivity of the antenna, wherein the directivity controller determines whether to adjust the directivity of the antenna based on a relation between a propagation characteristic at a time when the radio signal is received from the counterpart radio relay device in an operating period and an absolute value or a relative value serving as a threshold, and when it is determined to adjust the directivity of the antenna, the directivity controller transmits an adjustment start signal to the counterpart radio relay device and adjusts the directivity of the antenna, with interlocking with the counterpart radio relay device. |
