The base stations are all under the control of the Tower Company. Why are the signals of the three major operators sometimes very different?

Tower Company is only responsible for the construction and maintenance of supporting equipment such as computer room, tower and power supply. Tower Company was established to prevent the three major operators from repeatedly investing in infrastructure.

However, Tower Company is not responsible for the base station itself, but for the supporting facilities of the base station and the construction of the computer room, tower and indoor distribution system. As the base station equipment for signal transmission, the three major operators build and maintain it themselves. As far as the base station is concerned, it is mainly composed of BBU, RRU and antenna feed system.

In order to prevent the three major operators from repeatedly building towers and save land resources, the Tower Company was established. The tower company is only responsible for building the tower, and the three major operators each pay for renting the tower of the tower company. The tower can't send and receive signals, so the signal quality is only related to the distribution of the tower.

At this point, the conditions of the three major operators are the same, and there is no difference. The equipment installed by the three major operators on the tower is different, the equipment operation and maintenance ability is different, the equipment installation density is different, and the communication quality is of course different!

The newly-built iron tower site also has a platform. Generally, the first platform can achieve wide coverage, but the first platform can only put one operator's antenna, so other operators can only put the second or third platform, which will also lead to differences in coverage.

Finally, the investment in construction, although most macro stations are allocated to the iron tower, but now operators are studying new coverage methods as a supplement to the blind area of macro stations, such as room division, micro stations and so on.

The above is the explanation for why the base stations are all under the control of the Tower Company. Sometimes the signals of the three major operators are still very different. I hope my answer can help you.
