地铁隧道无线网络覆盖设计方案对比研究

摘要

With the development of China’s rail transportation, the subway has become an important choice for people to travel. How to provide stable, high-speed mobile network coverage in the subway has become a big problem for the three operators. In this paper, a branch of tunnel coverage was selected, and a case study of Tianjin Metro Line 6 was used to study the characteristics of two kinds of commonly used tunnel coverage. Strengths and weaknesses of both designs were summarized, providing guidance for future subway tunnel coverage design.%随着我国轨道交通事业的发展，乘坐地铁逐渐成为人们出行的重要选择，如何在地铁内提供稳定、高速的移动网络覆盖成为困扰运营商的一大难题。通过选取地铁覆盖中隧道覆盖这一分支，以天津地铁6号线一期工程为例，研究分析2种常用的隧道覆盖方案的特点，并总结出各自的优缺点，从而指导后续地铁隧道覆盖设计工作。
