摘　　要：由于采用大规模天线阵列(Massive-MIMO)等技术,5G移动通信基站在不同应用场景和终端集中程度下的电磁辐射强度有明显差异。为探讨5G移动通讯基站电磁辐射影响预测方法,参照国际电工委员会标准(IEC 62232)模拟5G基站射频电磁强度,设置并建立了天线NR下行PRB平均利用率为65.88%~98.58%和小区下行有效吞吐率为885.29~1147.30 Mbps的实际应用场景。同时,利用建立形成的稳定强电磁窄波,实测连续6分钟方均根检波示值,采用皮尔逊相关分析法对监测结果进行分析,发现实测值与理论模拟结果具有良好的相符性(p>0.95)。本研究可为5G基站电磁辐射环境监测的规范操作提供参考,也可为开展基站射频辐射强度模拟计算提供数据验证。Due to the application of large-scale antenna array(massive MIMO)and other technologies,the electromagnetic radiation intensity of 5G mobile communication base stations is significantly different under different application scenarios and terminal concentrations.To explore prediction methods for the impact of electromagnetic radiation from 5G base stations,the RF electromagnetic intensity of 5G base stations was simulated according to the International Electrotechnical Commission standard(IEC 62232),and the actual application scenario was set up in which the average utilization rate of downlink PRB of antenna NR was 65.88%-98.58%and the downlink effective throughput rate of the cell was 885.29-1147.30 Mbps.Besides,based on the stable strong and narrow electromagnetic wave that had been established,the root mean square value of the indication for 6 consecutive minutes was measured,and the monitoring results were analyzed with the Pearson correlation analysis method.It was found that the measured values were in good agreement with the theoretical simulation results(P>0.95).This study provides reference for the standard monitoring of the electromagnetic radiation environment of 5G base stations,and verifies the results of the simulation calculation of the RF radiation intensity of the base station.
