Title: COMMUNICATION SYSTEM
Abstract:
A server (4) manages the communication area of wireless communication between a base station (2) and a terminal (3). The server (4) holds information on the installation position of the base station (2), and information on the communication channel and radio field intensity to be used for wireless communication with the terminal (3). On the basis of the information on the communication channel and radio field intensity, the server (4) calculates the distance over which wireless communication between another base station (Y) and a terminal (B) within the communication area of said other base station (Y) will be subject to interference due to adjacent channel leakage when a terminal (A) within the communication area of a certain base station (X) performs wireless communication with said base station (X); on the basis of the information on the distance and the installation position, the server (4) calculates an output level at which said terminal (A), which is within the communication area of said base station (X), will not inflict interference on wireless communication between said other base station (Y) and said terminal (B) within the communication area of said other base station (Y) due to adjacent channel leakage when said terminal (A) performs wireless communication with said base station (X); and the server (4) notifies the output level to the terminal (A). Thus, it is possible to inhibit wireless communication between a base station and a terminal from being subjected to interference due to adjacent channel leakage.
