Abstract

The invention discloses a method for calculating the declination angle of an antenna of a mobile communication base station, which comprises the following steps of: acquiring information of all outdoor macro base station cells in an area needed to be calculated; calculating all cells within a maximum search distance set by a main cell so as to form a neighbor cell set; carrying out directional signal intensity contrast on the coverage direction of the main cell by adopting a directional signal intensity contrastive analysis method; circularly calculating discrete geographical position points; calculating the main coverage cell of a single discrete geographical position point, calculating the signal intensity of each discrete geographical position point, and calculating a main service cell of the discrete geographical position point according to path loss; calculating the coverage distancerection of each main cell according to the home condition of the main service cell of each discrete geographical position point; and calculating to obtain the declination angle of the antenna of each cell according to the altitude of the antenna of each cell and the coverage distancerection of each cell. The method has the characteristics of overall unified calculation and high degree of automation, so that the accuracy and the speed in the calculation of the declination angles are remarkably improved.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method for calculating the downtilt angle of mobile communication base station antennas based on coverage level prediction and combined with the actual distribution of sites. Background technique [0002] When planning a GSM mobile communication system base station, the downtilt angle of the base station antenna is generally set by the planner based on experience. The downtilt angle determined in this way is relatively subjective, and the coverage distance of the cell cannot be precisely controlled. If the downtilt angle is determined by coverage simulation software, the downtilt angle must be manually modified according to the coverage simulation diagram until it is deemed appropriate. This method makes the determination of the downtilt angle slow, and the simulation software is expensive, and the parameters are complicated to set, and the calculation time is long. In ord...
