The signal base station on the roof has the greatest influence on which floor of the whole building.

The influence of the signal base station on the roof of each floor of the whole building is similar, because the signal is transmitted by electromagnetic waves, and the base station transmits the signal to the mobile station (such as mobile phone) through the antenna, so the influence of the base station on the whole building is relatively uniform, rather than concentrated on a specific floor.

However, due to the influence of the height of the signal tower and the surrounding environment, some floors may receive weak signals. It depends on the height, location, coverage and occlusion of the surrounding environment of the base station.

Generally speaking, the influence of the floor on the signal is not a very significant factor, but more important is the setting and layout of the base station, as well as the performance and location of the user's equipment.
