Summary:
Recently, ICT has been introduced to various fields of fishery and marine work. For example, wireless access systems are used for realizing a broadband environment in coastal areas and on isolated islands. The authors also realized a marine broadband environment for small fishing vessels to manage aquatic resources. In order to establish stable use of wireless access systems, it is necessary to evaluate the characteristics of wireless access systems in severe conditions, such as anomalous tide levels caused by a typhoon or a tsunami. In this study, the authors evaluated the long-term characteristics of a wireless access system by constructing a 5 GHz band wireless access system that has propagation paths including the surface of the sea. As a result, we could obtain RSSI data when a typhoon approached, and we confirmed that the system could maintain communication quality. The authors also considered the possibility of the detection of anomalous tidal levels from RSSI of the wireless access system.
