高速铁路车地宽带无线通信方案比较研究

研究目的:目前作为无线调度的GSM-R技术已不能满足高速铁路车地宽带无线通信的需求,探讨高速铁路车地宽带无线通信的实现方案,为我国铁路宽带无线网络规划和优化方案提供依据和参考。研究结论:LTE技术是目前车地间宽带无线通信系统建设方案中比较理想的技术,既能提供安全、可靠的车地间宽带无线通信,又是今后车地宽带无线发展的方向,同时还符合目前国际铁路联盟确定的GSM-R向LTE-R的基本演进策略和步骤。

Comparative Research on Train- ground Wide Band Wireless Communication for High- speed Railway

Research purposes: As used for the wireless dispatching,the GSM-R technology can not satisfy the demand of the train-ground wide band wireless communication for the high-speed railway.So it is necessary to discuss the scheme for realize the train-ground wide band wireless communication for the purpose of providing the basis and reference to plan and optimization of the schemes for wide band wireless network of the China’s railway. Research conclusions:Now the LTE technology is an ideal technology for the train-ground wide band wireless communication.It not only can provide the safe and reliable train-ground wide band wireless communication,but also it is of the development trend of the train-ground wide band communication.At the same time,it tallies with the gradual tactics and procedure from the GSM-R to LTE-R defined by the International Union of Railways.
