With mobile communication’s development

base stations were densified by large-scale building as people’s demand for better mobile network was continuously increasing. Especially

some large squares required more base stations for Wireless coverage. The popularization of the distributed base station could partially solved the problem of site selection and station-building

which meant in a higher standard on power supply of the remote station. In this paper

I proposed a solution to the remote station’s power supply of large squares under the condition of limited resources and provided some specifi c construction methods for the reference.
