国内大多数地铁线路的综合承载应用LTE-M（Long Term Evolution for Metro），需要围绕LTE-M网络展开对其传输特性、系统稳定性的实验测试及分析，而由于设备成本和相关许可的限制，在真实的轨道沿线测试不仅耗时而且成本很高。为了解决这个缺点，在实验室中开发仿真工具和测试程序，用于执行具有明确操作规范和满足测试结果需求的测试架构是非常必要的。本文结合硬件和软件平台，在实验室内真实再现城市轨道交通基础设施端到端的业务和场景，并给出LTE-M无线通信系统零现场测试方案和测试结果，有效证明零现场测试的可行性。

LTE-M is used for the integrated bearing of urban rail transit in China. It’s necessary to carry out experimental testing and analysis of LTE-M on transmission characteristics and system stability. Testing along real-world rail lines is time-consuming and costly due to equipment costs and licensing restrictions. It’s important to develop a zero-on-site testing，which comprises simulation tools and testing procedures for carrying out open tests with clear operational rules and simple certification of test results. This paper combines hardware and software platforms to truly reproduce the end-to-end services and scenarios of urban rail transit infrastructure in the laboratory, and presents the zero on site testing scheme and test results of LTE-M wireless communication system, effectively demonstrating the feasibility of zero on site testing.
