1概述通信GSM-R工程是高速铁路不可或缺的重要组成部分,我国高速铁路工程基本采用单网交织冗余的GSM-R网络。高速条件下运行的多普勒效应和电磁干扰会对列控信号传输造成巨大的负面影响,而且GSM-R网络也不同于普速铁路的450MHz无线列调系统。因此,为保证
1 Overview Communication GSM-R project is an indispensable part of high-speed railway. The high-speed railway project in our country basically uses single-network interlaced GSM-R network. The Doppler effect and electromagnetic interference of high-speed operation will have a tremendous negative impact on the train control signal transmission, and the GSM-R network is also different from the 450MHz wireless transmission system of the general railway. So, for sure
