Under the “dual carbon” goals, enhancing the energy supply for communication base stations is crucial for energy conservation and emission reduction. An individual base station with wind/photovoltaic (PV)/storage system exhibits limited scalability, resulting in poor economy and reliability. Reliable communication between maintenance crews and control centers is critical — especially during turbine malfunctions or scheduled inspections. Traditionally, operators relied on analog radios or simple intercoms. As global offshore wind power advances toward deeper, farther waters, harsh Operation and Maintenance (O&M) environments, equipment heterogeneity, and flaws in existing communication (e.
