Background
With the requirement of high frequency communication and supporting high capacity and high speed of 5G base stations, the realization of denser network coverage by a large number of tiny base stations becomes a problem to be solved in the 5G era. The combination of the small base station and the street lamp can share the charging device, so that energy is saved, and the problem of power supply of independent arrangement of the small base station is solved.
