TD-SCDMA移动通信基站电磁辐射的运行期环境影响预测与分析

浙江省的3G网络TD-SCDMA基站正在大量建设,本文通过选取在温州市已经运行两个TD-SCDMA基站的电磁辐射现状监测,对未建或在建基站的电磁辐射环境影响进行了预测与分析。由温州市两个已建基站的类比监测和分析可见,基站正常运行时对周围环境的电磁辐射贡献相对较低,类比监测结果均低于评价标准值;拟建基站对周围电磁辐射水平的贡献随与发射天线的距离增大而减小,若天线主瓣前方无遮挡物,则单个基站的电磁辐射贡献值能符合电磁辐射环境保护要求。

3 g network td-scdma base station in zhejiang province is a large number of construction, this paper selected in wenzhou has been running two electromagnetic radiation status of td-scdma base station monitoring, ,have not built or under construction base station electromagnetic radiation environmental impact forecast and analyzed. By wenzhou two analogy monitoring and analysis of the base station, base station during normal operation of electromagnetic radiation on the surrounding environment contribution is relatively low, the analogy to the monitoring results are under evaluation standard; Proposed contribution to the electromagnetic radiation levels around the base station decreases with increasing the distance and the transmitting antenna, the antenna if main lobe ahead without shelter, the electromagnetic radiation contribution value of a single base station can conform to the requirements of the electromagnetic radiation environmental protection
