method for correcting indoor LTE wireless signal distribution test data

Abstract

The invention also relates to a method for correcting the indoor LTE wireless signal distribution test data, which comprises a method for correcting the data in an indoor scene, and specifically comprises the following steps of: (1-1) caching the measurement data when the signals are abruptly changed before and after an obstacle; (1-2) detecting the mutation point by the test equipment, caching the current measurement data and the measurement position, and continuing to measure; (1-3) judging whether the test signal and the jump point keep consistent in trend and reach a certain number of measurement points or not, and if yes, keeping the current moving route away from the transmitter; otherwise, if the cache point is an abnormal point, processing the abnormal point through an interpolation algorithm, and recording cache point data. By the adoption of the method for correcting the indoor LTE wireless signal distribution test data, in order to solve the problems of indoor signal blind areas and non-uniform field intensity distribution, the equipment utilization rate is effectively increased through testing, and the facility construction cost is reduced.

Description

technical field [0001] The invention relates to the field of wireless signal testing, in particular to the field of wireless signal test data correction, and specifically refers to a method for correcting indoor LTE wireless signal distribution test data. Background technique [0002] The indoor distribution system is a solution aimed at indoor user groups to improve network quality and equipment utilization. The indoor antenna distribution system is used to evenly distribute the signal of the mobile base station in every corner of the room, so as to ensure that the indoor area has an ideal signal. cover. In order to solve the problem of indoor signal blind spots and uneven distribution of field strength, it is particularly important to conduct indoor distribution tests in the early stage of system construction. Passing tests can effectively improve equipment utilization and reduce facility construction costs. [0003] When testing indoors with few obstacles, using a pilot ...

AI Technical Summary

Problems solved by technology

Common switching scenarios include indoor and outdoor switching, elevator internal and external switching, and underground parking lot switching. At the same time, at these test locations, the signal strength of the external base station may also be much greater than the signal strength of the pilot transmitter, resulting in errors in the measurement data of the receiving device

During indoor testing, because of obstacles such as indoor pillars, desks, doors and windows, the measured signal strength will also change suddenly

If the test data in the above scenarios are not specially processed, it will interfere with the subsequent data analysis and affect the analysis results
