高速铁路长大隧道GSM-R网络冗余组网方案分析OA

Long tunnels of high-speed railway need to be covered according to GSM-R redundancy networking scheme.At present,GSM-R network can use two kinds of digital relay equipment:digital repeater and distributed base station.Both of the equipment have a variety of networking solutions.This paper analyzes the fault response capability,carrier frequency utilization,construction cost and other aspects,compares various GSM-R digital relay equipment redundancy networking schemes in high-speed railway tunnels,and proposes the application scope and performance advantages and disadvantages of various schemes.
