Abstract

A train journey could be an ideal moment to answer a phone call, read an e-mail or browse the Internet on a personal device such as a smartphone, tablet or laptop. Unfortunately, a train is a very challenging environment to provide a mobile network service to due to attenuation and bad coverage leading to dropped phone calls and unreachable Internet services. Improving mobile network service on-board trains, however, is costly and should be planned carefully. A multi-criteria comparison of different deployment options is therefore essential toward an optimal investment decision. But, the impact of the choice of on-board distribution system is often overlooked. This article compares three types of on-board signal repeaters side-by-side: IP-based data access points, wideband repeaters and small cells. The differences in terms of network coverage, human exposure, deployment cost, revenue model and telecommunications policy are analyzed for each of them.

列车上的互联网:列车上蜂窝连接的车载部署选项的多标准分析

在火车上，你可以用智能手机、平板电脑或笔记本电脑等个人设备接听电话、阅读电子邮件或浏览互联网。不幸的是，在火车上提供移动网络服务是一个非常具有挑战性的环境，因为衰减和覆盖不好会导致电话掉线和无法访问互联网服务。然而，改善列车上的移动网络服务是昂贵的，应该仔细规划。因此，对不同部署选项进行多标准比较对于做出最佳投资决策至关重要。但是，车载配电系统选择的影响往往被忽视。本文比较了三种类型的机载信号中继器:基于ip的数据接入点、宽带中继器和小型基站。分析了它们在网络覆盖、人员暴露、部署成本、收入模式和电信政策方面的差异。
