郑州地铁专用无线频率规划探讨

Discussion on radio frequency planning for Zhengzhou Metro

在地铁无线集群系统建设和运营中,专用无线频率规划是其中最为重要和基础的工作。本文介绍了TETRA系统和郑州地铁无线频率规划的原则,针对4种线路条件提出了详细的无线频率规划方法和思路。通过对17条线路的提前无线频率规划,不仅为线网专用无线通信系统建设及城市轨道安全运营提供了技术支撑,而且为后续无线频率申请提供了数据依据。

Throughout the deployment and operation of Metro Wireless Cluster System, private wireless frequency planning is the most important and fundamental jobs. The article will give you a general introduction of TETRA systems together with the wireless planning principles of Zhengzhou Metro, then frequency planning methodology and solutions will be suggested according to the four kinds of metro lines scenario. The advance wireless planning of seventeen metro lines have been finished, which can not only provide technical support to the deployment of metro wireless communication system and guarantee the safe operation of metro service, but also provide valuable data information for subsequent wireless frequency application.
