4G基站的电磁辐射影响分析

Analysis of electromagnetic radiation from 4G base station

随着4G基站的建成运行,4G基站的电磁辐射影响将受到人们的关注。本文对铜仁市碧江区已运行的10个基站进行电磁辐射理论影响计算和电磁辐射的实际监测结果分析,结果表明:4G基站天线轴向功率密度值是随着距离天线距离的增加而快速衰减;4G基站在正常运行状态下,天线主射方向实测结果均未超过0.08 W/m2;4G基站的实际电磁辐射影响小于理论计算结果。

with the 4G base stations put into operation, the issue of electromagnetic radiation from them attracted more and more attention. This paper analyzed the actual monitoring results and theo- retically calculated values of electromagnetic radiation from 10 in - use 4G base stations in Tongren city, Guizhou Province, and found that the axial power density decreased significantly with the in- crease of distance from the antenna. When the 4G base stations were in normal operating conditions, the electromagnetic radiation along the main radiation direction of the antenna were measured as less than 0.08 W/m2. The actual intensity of electromagnetic radiation of 4G base station was weaker than the theoretical calculation results.
