摘要
5G网络高频段高穿损特征带来站址数量增加的压力,为降低工程选址难度,同时提升高铁场景的5G覆盖性能,本文从分析高铁5G天线入手,指出了5G站间距小于4G网络、以及传统天线在线性道路覆盖存在的远近效应影响是高铁5G网络性能的重要因素。本文详细阐述了天线波束调整能力增强技术和实现方案,并以测试实例验证了这种技术在高铁组网时的性能提升效果。考虑到工程应用需求,本文还对比了不同实现方案在覆盖性能、造价和工程应用等方面的差异,提出高铁场景下的5G天线选型应用建议。
This paper analyzes the key content of 5G network coverage planning in high-speed rail scenarios,namely antenna technology and its selection and application.Started from the challenges of higher losses and the phenomenon of weak coverage areas caused by antenna proximity effects has increased the demand for antenna beam adjustment capability.In order to further improve coverage,it compares antenna designs and technical performance of different technical solutions.Also make multiple comparative analyses are conducted from the aspects of coverage performance,cost,and engineering applications.Finally,suggestions for the selection and application of 5G antennas in high-speed rail scenarios are proposed.
