It is about.

Mobile communication is possible by telephone or data communication through a mobile terminal having a communication function and a base station antenna. The communication antenna installed outdoors may be installed for each operator by estimating coverage or communication load through a predetermined prediction. However, changes may occur such as deviations from predictions or changes in the surrounding environment. In addition, as data communication is booming in recent years, communication loads are often varied in regions and time zones in mobile communication systems.
