SoftBank Group is piloting AI-controlled cellular base stations powered by solar panels and a 3 kW wind turbine in Ichihara City, Chiba Prefecture. The system reduces energy use while maintaining service quality by storing excess power in batteries and switching to the grid when needed. AI manages the station's "sleep" mode to lower power consumption during low communication traffic, making it suitable for deployment in remote areas. The compact design and AI analysis allow for a broader selection of cells without compromising communication quality. SoftBank plans to expand testing of the wind- and solar-powered base stations in the future.
