摘要
以北京19号线城市轨道交通的无线通信系统建设为例,探究LTE技术在城市轨道交通中的应用效果。从LTE技术特征角度出发,对LTE-M系统的应用情况进行测试,重点对网络架构的信息传输能力和综合承载能力进行分析。结果表明,19号线基于LTE技术设计的无线通信系统具有较高的信息传输速率和综合承载能力,整个系统在测试过程中并未发生丢包现象,证明该技术的应用能够满足案例地区城市轨道交通对无线通信系统的要求。
Taking the wireless communication system construction of Beijing line 19 urban rail transit as an example, this paper explores the application effect of LTE technology in urban rail transit. From the perspective of LTE technical characteristics, the application of LTE-M system is tested, focusing on the information transmission capacity and comprehensive carrying capacity of the network architecture. The results show that the wireless communication system of line 19 based on LTE technology has high information transmission rate and comprehensive carrying capacity, and the whole system has no packet loss in the test process, which proves that the application of this technology can meet the requirements of urban rail transit for wireless communication system in the case area.
