基于5G移动通信网络的城市轨道交通PIS系统应用探究

5G移动通信网络采用新一代蜂窝移动技术，其数据传输速率高于第四代移动通信网络的十倍之多，将第五代移动通信网络应用于城市轨道交通PIS无线系统中，可改善目前基于无线局域网构建的PIS系统中通讯信号易干扰、故障多等弊端。本文从LTE-A技术、MIMO增强技术、MEC技术等5G移动通信关键技术为切入点，从城市轨道交通系统的核心层、接入层、应用层出发，构建全新的智慧轨道交通系统。

Research on the application of urban rail transit PIS system based on 5G mobile communication network

5G mobile communication network adopts the new generation cellular mobile technology, and its data transmission rate is ten times higher than that of the fourth generation mobile communication network. The application of the fifth generation mobile communication network in the PIS wireless system of urban rail transit can improve the disadvantages of easy interference and many faults of communication signals in the PIS system based on wireless LAN. Starting from the key technologies of 5G mobile communication such as LTE-A technology, MIMO enhancement technology and MEC technology, this paper constructs a new intelligent rail transit system from the core layer, access layer and application layer of urban rail transit system.
