简谈铁路通信系统向LTE-R的发展与演进

Evolvement of Railway Communication System to LTE-R System

简要介绍宽带移动通信系统LTE-R,通过与目前GSM-R系统相比较,发现LTE-R在性能、安全等方面存在优势,更适用于铁路的快速发展,GSM-R系统向LTE-R演进也成为未来必然趋势。

The paper introduces LTE-R broadband mobile communication system. Through comparison between LTE-R and GSM-R systems, it is considered that LTE-R system has advantages in the performance and security and is more suitable for the rapid development of railways, and GSM-R system will evolve to LTE-R system as well.
