5G移动通信基站电磁辐射监测与评价

Monitoring and Evaluation of Electromagnetic Radiation of 5G Mobile Communication Base Station

以福州市5G通信基站为例,实地测量了3个典型5G基站。选取不同终端空间位置、应用场景、传输时长和断面距离作为变量,测试单个终端下的基站电磁辐射水平,结果表明数据传输时电磁辐射水平较高,但也远小于电磁环境控制限值。通过分析测试数据,建议测量时测试终端置于基站与选频测试仪器水平连线后端,应用场景选择数据传输且监测时保证测试终端和基站6 min数据的稳定连接。

Taking Fuzhou 5G communication base station as an example,three typical 5G base stations were measured on the spot.Different terminal space locations,application scenarios,transmission duration and section distance were chosen as variables to test the electromagnetic radiation level of the base station under a single terminal.The results showed that the electromagnetic radiation level during data transmission was high,but also far less than the electromagnetic environment control limit.By analyzing the test data,it was recommended that the test terminal should be placed at the back end of the horizontal connection between the BTS and the frequency selection test instrument during the measurement.The application scenario selected data transmission and the stable connection between the test terminal and the BTS for 6 minutes during the monitoring.
