摘　　要：根概述了5G移动通信基站环境影响特性及电磁辐射情况,选取通信基础设施发达、人口密度大的上海市中心城区静安区为代表性研究地点,对5G通信基站周围电磁辐射水平进行了监测,发现电磁辐射水平随5G终端个数和使用流量的增加而增大;相同流量下,电磁辐射水平随流量下载时长的增大而增大。分别测量了单个5G终端在游戏娱乐(抖音直播)、视频交互(微信视频)、虚拟购物(淘宝直播卖货)、数据传输(APP下载)场景的基站电磁辐射情况,发现所有应用场景下的电磁辐射水平均低于国家标准《电磁环境控制限制》(GB8702-2014)中公众曝露限制0.4W/m^(2)。Environmental impact characteristics and electromagnetic radiation status of 5G mobile communication base stations were outined.Jing'an District in the Shanghai City Proper,where is densely populated with well-laid communications infrastructure,has chosen as a representative place for the study.Electromagnetic radiation levels at the surroundings of a 5G communication base station were monitored,and the findings showed that the levels would rise along with more 5G terminal numbers or more data flows under using whilst increasing with prolonged downloading duration under the same data flows.The electromagnetic radiation status of base station at a sole 5G terminal was measured individually in the scenarios of game/entertainment(live streaming of Tik Tok),video interaction(WeChat videos),virtual shopping(Taobao live selling),and data transmission(downloading of application programs).The electromagnetic radiation intensities in all scenarios were found below the public exposure limit of 0.4 watt per square metre specified in national standard<Controlling limits for electromagnetic environment>(GB 8702-2014).
