5G通信在城市轨道交通的应用

The application of 5G in Urban railway

简述了当前发展迅猛的5G通信(The fifth generation mobile communication network第五代移动通信)现在的发展状况、适应的五大应用场景和四大关键技术。简述了城市轨道交通中的通信系统,按不同的通信方式对通信系统进行分类,分为有线通信系统和无线通信系统两类。提出了一种新型的车-车通信概念,再结合5G通信与4G通信技术参数的对比,分析出5G通信在城市轨道交通中应用的可行性及优势。最后还就5G通信技术在城市轨道交通应用中所遇到的问题以及相关研究进行了讨论。

Summarized the current development status of the rapidly developing 5G communications, the five major application scenarios and four key technologies. A brief description of the communication system in urban rail transit. According to different communication methods, the communication systems are classified into two types： wired communication systems and wireless communication systems. Proposed a new type of train to train communication concept. Combined with the comparison of 5G communication and 4 G communication technology parameters, the feasibility and advantages of 5G communication in urban rail transit are analyzed. Finally, this paper also discusses the problems encountered in the application of 5G communication network in urban rail transit.
