Problems solved by technology

[0005] The operability is not strong: the number of antennas in the operation of the GSM network is huge, and the antennas are sent to the antenna space darkroom laboratory for evaluation one by one, which lacks operability, so it can only be tested by sampling
[0006] High cost: After the antenna is disassembled, a spare antenna needs to be used, and the cost of disassembly, installation, and transportation is extremely high
[0007] Long operation cycle: From stopping the operation of the antenna, disassembling the antenna, sending the antenna to the antenna space darkroom laboratory for testing, and then reinstalling the antenna, the overall operation process requires a long cycle and poor timeliness. If the number of antennas is large, it is difficult to avoid damage to the site. impact on network operations

Abstract

The invention provides a method and system for coverage performance evaluation of an antenna. The method comprises the following steps that: sweep frequency data of a testing sampling point related to a target evaluation antenna are obtained; the testing sampling point is mapped to an antenna evaluation coordinate system according to the sweep frequency data; a sample statistic unit of the antenna evaluation coordinate system is obtained, wherein the sample statistic unit contains one or more testing sampling points; actual measurement signal field intensity and theoretical signal field intensity of the target evaluation antenna in the sample statistic unit are obtained; according to the actual measurement signal field intensity and the theoretical signal field intensity of the target evaluation antenna in the sample statistic unit, a preset antenna coverage performance parameter of the target evaluation antenna is evaluated. According to the invention, under the circumstances that the running of the existing network is not influenced, the coverage performance of the antenna can be evaluated accurately and rapidly.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method and system for evaluating antenna coverage performance. Background technique [0002] There are a large number of antennas running in the GSM network. If the coverage performance index of the antenna is not up to standard, it will affect the signal quality of the GSM network. [0003] In the prior art, the antenna space darkroom laboratory is mainly used to evaluate the coverage performance of the antenna, and determine the problematic antenna whose coverage performance index fails. The method of using the antenna space darkroom laboratory to evaluate the coverage performance of the antenna is to stop the operation of the antenna, disassemble the antenna, and then send the disassembled antennas one by one to the antenna space darkroom laboratory for testing and evaluation. [0004] Although the above method can check various coverage performances of the antenna, it...
