GSM与GSM-R网间干扰问题解决过程

随着我国高速铁路和客运专线的快速建设,中国移动GSM网络和铁路GSM-R网间干扰越来越严重,严重影响了铁路运营的安全性和可靠性。从定位干扰区域、分析测试数据、解决干扰问题和电磁环境复测4个步骤入手,对解决GSM与GSM-R网间干扰问题的过程进行研究。

With the rapid construction of high speed railway and Dedicated Passenger Railway lines in China,the interference between CMCC GSM network and GSM-R network becomes more and more seriously and imposes a strong impact on the security and reliability of railway operation. The four steps process of solving the interference problem between GSM and GSM-R network,including locating interference region,analyzing test data,solving interference problem and EMC retest,are studied in this article.
