Abstract: To address the challenges posed by complex radio propagation conditions in coastal waters, the difficulty of maintaining continuous wireless coverage along shipping lanes, and the stringent network reliability requirements for maritime surveillance and emergency communications, this study investigates the planning and deployment of coastal maritime wireless broadband private networks. Based on an analysis of the necessity for building China's coastal wireless broadband private network, construction plans for the Yangtze River Estuary and Qiongzhou Strait wireless broadband private networks are proposed, and the performance of the experimental private network is simulated and verified. The simulation results show that the private network system can meet the broadband communication needs of maritime supervision, search and rescue, emergency response, and other services. These research results provide useful exploration and key guidance for the future construction of wireless broadband private networks.
