九江枢纽GSM-R系统覆盖方案设计

Coverage Scheme of GSM-R System in Jiujiang Railway Hub

南昌铁路局九江枢纽内线路较多,通过合理布局枢纽内基站小区和频率,实现各线之间无线网络的合理衔接,消除各线无线网间频率干扰,实现GSM-R无线网资源共享,保障GSM-R系统服务质量。同时进行了仿真验证,给出了仿真结果,为其他类似工程建设方案提供借鉴。

There are too many lines within the Jiujiang hub of Nanchang railway administration. By properly arranging the zones and frequencies of those base stations within the hub,the wireless networks of those lines can be connected up while the frequency interferences of those wireless networks can be eliminated. Therefore, the resource sharing of GSM-R wireless network is realized and the service quality of the GSM-R system can be guaranteed. Meanwhile, the simulation was conducted to verify the coverage scheme and the results of the simulation are given as reference for other similar projects.
