摘要: 全新的上盖物业结构设计使其下方的铁路建筑结构不同于常规动车所设计,对其中的无线网络设计带来一定困扰。因此有必要针对该特殊环境,对其中的无线覆盖情况进行研究,以方便今后类似场景下的无线网络规划。结合杭州西动车运用所实地工程项目,通过比较全向天线和定向天线在该环境下对无线覆盖效果的影响,探讨此种铁路环境下的无线系统设计规则,最终确定使用定向天线在此类场景中进行无线网络覆盖的方案为更优方案。

Abstract: The new superstructure structure design makes the railway building structure below it different from the conventional EMU depot, which brings certain troubles to the wireless network design. Therefore, it is necessary to study the wireless coverage in this special environment, so as to facilitate future wireless network planning in similar scenarios. Combined with the Hangzhou west EMU depot project, this paper compares the influence of omnidirectional antenna and directional antenna on wireless coverage and discusses the design rules of the wireless system in such a railway environment. Finally, it is determined that the scheme of using the directional antenna for wireless network coverage in this kind of scenario is better.

Key words: EMU depot, superstructures, wireless coverage
