Abstract: A point-to-point radio apparatus (10A or 10B) is configured to perform a first channel search (S12) to search for an idle channel available to use in a first point-to-point radio link (11A) in response to receiving a first notification (S11) indicating that a second point-to-point radio link (11E) operated by another point-to-point radio system (1E) is unavailable. This contributes to, for example, efficient channel searches in point-to-point radio systems.

Abstract: Provided are an antenna angle adjustment device, an antenna angle adjustment system, an antenna angle adjustment method, and a communications device, whereby the angle of an antenna can be adjusted to a direction in which direct waves can be more reliably received. A direction information generation unit 41 generates direction information indicating a direction of one antenna from another antenna. A range information generation unit 42 generates range information indicating a range of a main beam of the another antenna. A determination unit 43 determines, based on the range information and the direction information, whether or not the one antenna is in a range indicated by the range information.

Abstract: A radio apparatus (1) notifies a radio apparatus (2) of a new reverse channel to be used in a reverse link (52) and another idle reverse channel(s). If reachability of a forward link (51) is lost by the use of a new forward channel associated with the new reverse channel, the radio apparatus (2) determines a further new forward channel from among forward channel(s) associated with the idle reverse channel(s) of which the radio apparatus (2) has been notified by the radio apparatus (1). This contributes, for example, to a safe switch of the bidirectional operating radio channels without using a redundant connection, when frequency-division multiplexing with fixed frequency spacing is used.

Abstract: A communication apparatus (1) includes a communication unit (11) and a control unit (12). The communication unit (11) is electrically connected to an antenna (10) attached to a structure (40). The control unit (12) controls, based on a quality index indicating communication quality related to vibrations of the structure (40), a radio communication parameter to be applied to the communication unit (11). This can contribute, for example, to suppression of degradation of the communication quality of a radio link which occurs due to the vibrations of the structure to which the communication apparatus is attached.
