Background

With the advent of the 5G era, new communication equipment has placed higher demands on the power and density of the equipment rooms and base stations of communication carriers. The traditional power supply technology of the base station is no longer suitable for the construction or reconstruction of the base station and the machine room in the area with dense people flow.
