The communication tower was taken over by the Tower Company. What are the base station maintenance personnel of China Unicom doing?

According to the current trend, the tower company is still very promising. In the future, Tower Company will be responsible for the construction and maintenance of "supporting" equipment in base station towers and base stations of various operators. Therefore, the recruitment of Unicom's base station maintenance personnel should mainly do basic maintenance work. However, it is hard to say whether the equipment of the base station will be developed in the future and maintained by the Tower Company.
