摘要
为了解决5G高铁部署中面临的信号穿透损耗和多普勒频谱极大而导致的覆盖和容量受限的问题,开展了新型高铁架构研究和高铁天线发展趋向的研究,在分析5G高铁业务需求的基础上,介绍了三类5G高铁部署方案的架构,提出了高铁沿线天线技术研究方向,为5G高铁部署方案提供参考。
In order to solve the problems of coverage and capacity limitation caused by signal penetration loss and excessive Doppler spectrum during 5 G high-speed rail deployment,the development trend of new 5 G high-speed rail network architecture and antenna feeder were studied.The research direction of antenna technology for the high-speed railway was introduced,which provided a reference for 5 G high-speed railway deployment.Based on the analysis of 5 G high-speed rail service requirements,three types of 5 G high-speed rail deployment schemes are proposed.
