| Abstract: | The railway digital mobile communication system(GSM-R)mainly carries voice service,with little da?ta service and low data rate,so the development of Railway broadband mobile communication system(LTE-R)is an inevitable trend.It introduces the structure and differences of the two systems.This paper compares and analyzes the technical requirements and detection methods of LTE-R and GSM-R terminal devices from the aspects of func?tion,business,performance and environmental requirements,and points out that the testing methods of terminal devic?es are quite different due to the different technical requirements and implementation modes of the two systems. |
