摘要
基于LTE(长期演进)技术车地无线通信,就乘客信息系统的业务,深入讨论了系统覆盖、时钟同步、区间隧道切换、天线模式等方案。并在此基础上,建立了系统测试环境。测试结果表明:LTE无线传输可很好地承载乘客信息系统的各种业务,具有较好的实用价值。
Based on LTE wireless communications between train and ground, and combined with the service of passenger information system, some schemes like the system coverage, clock synchronization, hand off in tunnel, antenna pattern and so on are discussed. On this basis, a test environment of TD LTE is established. And the results show that LTE wireless transmission has better practical value, it is a good system to carry a variety of passenger information service.
