浅谈地铁隧道场景中运营商信源配置方案

Discussion on the Information Source Configuration Scheme for Operators in Subway Tunnel Scenarios

地铁作为一种现代化交通工具,在日常生活中已经成为百姓出行的首选,为了满足大众乘坐地铁出行时手机信号畅通,运营商对地铁信号的覆盖高度关注,结合地铁隧道内具有封闭性强,无线环境简单,网络建设资源受限的特点,文章通过对隧道内各运营商的链路预算分析,结合不同网络制式的特点,多角度分析实现地铁隧道内最优化的信源配置方案。

As a modern means of transportation,subway has become the first choice for people to travel in daily life,In order to meet the unblocked mobile phone signal when the public takes the subway,operators pay high attention to the coverage of subway signal,and combine the characteristics of subway tunnel with strong closure,simple wireless environment and limited network construction resources.By analyzing the link budget of each operator in the tunnel and combining the characteristics of different nctwork standards,this paper analyzes the optimal information source allocation scheme in the subway tunnel from multiple angles.
