摘要
TETRA(泛欧集群无线电)专用通信系统在我国广泛应用于公共安全、轨道交通等专业领域已达14年。通过研究上海轨道交通10号线全自动运行线路上采用的此类专用通信系统,实地分析这些TETRA的应用场景,总结出TETRA在窄带环境中的特点,讨论了TETRA在全自动运行下可新增的服务,将TETRA的应用向更深更广的层次扩展。
The TETRA(trans European trunked radio)dedicated communication system has been widely applied in public security,rail transit and other professional fields in China for 14 years.Through analyzing the TETRA communication system used on Shanghai metro Line 10 fully-automatic operation(FAO),the scenarios of TETRA application are analyzed in the field,the characteristics of TETRA in the narrow-band environment are summarized.In current technical background,the new available services of TETRA are discussed,in order to expand the application of TETRA system to a deeper and wider level.
