Embodiment 2

[0070] It can be known from the prior art that low-cost magnetic sensors measure azimuth angles are susceptible to interference, and solutions with higher accuracy have higher costs. For this reason, Embodiment 2 of the present invention proposes a method for automatically obtaining the azimuth angle of a base station antenna.

[0071] A base station often needs to install more than 3 pairs of antennas. If it is a multi-system system, the number of antennas will increase exponentially. If a reference direction can be firstly defined on the base station, the azimuth angle of the antenna itself can be obtained only by measuring the angle between each antenna and the reference direction, which will be described in detail below.

Description

technical field [0001] The present invention relates to the field of wireless technology, in particular to a method, device and system for automatically acquiring the azimuth angle of a base station antenna. Background technique [0002] In the mobile communication system, the engineering parameters of the base station antenna directly affect the coverage direction and range of the wireless signal, which is an important basis for network optimization. The industrial parameters of the base station antenna mainly include azimuth, downtilt and hanging height. Because base station antennas are generally directional antennas, the azimuth angle directly determines the main coverage direction of the antenna. Accurate measurement of the azimuth angle of the antenna is very important to ensure network coverage. [0003] At present, the azimuth angle measurement of the base station antenna generally adopts the following means: [0004] Existing Solution 1: Measuring with a compass ...
