杭州市典型共站移动通信基站周围电磁环境影响调查与研究

在4G基站快速增加的背景下,基站共站已成为较为普遍的架设方式.根据移动通信基站的发展趋势和工作原理,选取典型共站的移动通信基站,按照测量规范进行布点,了解基站周围电场强度的大小、楼顶架设基站的建筑物内部电场强度,以及周围建筑物室内的电场强度垂直方向的变化规律.分析结果表明,只要基站选址合理,天线面板角度与高度能尽量避开周围环境保护目标的方向,共站的基站运营时周围环境的电磁辐射水平可以满足相应的评价标准,不会对周围的环境造成明显的影响.

Investigation and Research on Electromagnetic Environment Effects from Typical Co-sited Mobile Communication Base Station in Hangzhou

Under rapid expansion of 4G base station, co-sited communication base station has become more common.Ac-cording to the development trend and the working principle of mobile communication base station, this paper selectsa typical co-sited mobile communication base station tounderstand the intensity of electric field around the base station, the electric field inten-sity of the building, and the change of the electric field intensity in the surrounding buildings.The analysis results show thatas long as the base station location is reasonable, the antenna panel angle and height can avoid the direction of the surrounding environ-ment protection.The electromagnetic radiation level of the surrounding environment can meet the corresponding evaluation crite-ria, and will not cause a significant impact on the environment.
