Analysis Of Electromagnetic Environment Of 5G Mobile Communication Base Station And Management Method

With the rapid development of 5G technology,the number of 5G base stations is increasing,making the electromagnetic radiation hazards brought by 5G base stations more and more attention.Because 5G used large-scale MIMO technology,can achieve more accurate beam informs,this makes the traditional prediction method,the base station can not accurately predict 5G base station electromagnetic radiation level,may overestimate the results,therefore,the analysis of 5G base station electromagnetic radiation environment study,can reduce the panic of people,can also for 5G mobile communication base station electromagnetic radiation provide theoretical basis for the test.The main work of this paper has two parts:Based on the beamforming characteristics of 5G system,this paper conducts simulation and prediction analysis on the electromagnetic environment of 5G mobile communication base station under different business modes and different user distribution scenarios,and verifies the validity of the simulation through test experiments.Firstly,the antenna pattern of different scenes was simulated by building the Matlab communication system,and then the terrain of the actual environment was modeled by HFSS.Finally,the electromagnetic radiation intensity was predicted by the complex electromagnetic simulation software CEMS based on ray tracing.And through the specific 5G base station for the corresponding scene of the electromagnetic radiation intensity measurement,to verify the effectiveness of the simulation results.In order to improve the test efficiency and standardize the test process,this paper designs a laboratory management system based on the base station test.This system from the resource management,testing business management and quality control management three aspects,the system has carried on the detailed design.The basic resource module includes the management of personnel,equipment and standards,the test business module includes the management of projects,contracts,test activities,customer service and accident reports,and the quality control module includes internal audit,non-conformance items and management review,etc.The laboratory management system based on the base station test business designed in this paper can achieve the following goals,to achieve a comprehensive control of personnel,equipment,standards and other basic resources,to achieve the flow management of the base station and other test tasks,automatic generation of test reports,to achieve information management.
