摘要
高铁覆盖场景复杂且高速列车运行速度快,切换频繁,多普勒效应明显。如何更好地覆盖高铁,为客户提供更加优质的服务,也成了网络建设的重点难点问题之一,针对高铁隧道场景的覆盖方案,对进一步提升高铁场景覆盖能力作一些探讨。
High-speed rail coverage scenarios are complex,high-speed trains run fast,switch frequently,and the Doppler effect is obvious.How to better cover high-speed rail and provide customers with better services has also become one of the key and diffi cult problems in network construction.This article focuses on the coverage of high-speed rail tunnel scenarios and discusses further improving the coverage of high-speed rail scenarios.
