6. First of all, answer the question of the title: base station sharing is required by the General Administration of communications in recent years. Otherwise, repeated construction will waste resources. The only difference between the base stations of China Mobile, China Unicom and China Telecom is the BTC (transmitter receiver) and the antenna, and then use their own optical fiber. I often go to the three in one base station. In addition to the BTS and the antenna, the power supply, machine room, tower, battery and air conditioner are shared to save resources
however, the BTS power of the three companies is not necessarily the same, so you have different signal strength in the same place. Or you don't have to be in a co location
hard typing, encouragement, give the best answer!
