GSM-R与LTE-R网络对比

Comparison of GSM-R and LTE-R Network

随着运输和养护技术的提高,窄带GSM-R网络已不能满足新业务的需求,宽带LTE-R系统成为下一代铁路无线通信系统的发展方向。本文对GSM-R和LTE-R的系统架构、接口及协议进行对比,并展望铁路无线移动通信技术的未来发展。

With the improvement of transportation and maintenance technology, the narrowband GSM-R network can not meet the needs of new services. Therefore, the broadband LTE-R sys-tem becomes the direction of next generation railway wireless mobile communication system. This paper compares the system architecture, interfaces and protocols of GSM R and LTE-R, and the future development of railway wireless mobile communication technology is prospected.
