上海市轨道交通无线通信频率规划及配置应用

Planning and Assignment of Shanghai Metro Wireless Frequency

轨道交通专用无线通信系统为调度指挥提供安全可靠的无线通信手段,是指挥列车运行必不可少的专用通信工具。随着轨道交通的发展,无线通信系统网络越来越庞大,频率资源越来越紧张。将有限的频率资源与实际现状以及运营需求结合起来,能起到促进系统动能发挥、提升管理水平、降低建设投入和提高工作效率的作用。介绍了800MHz Tetra数字集群无线通信在上海市轨道交通范围的网络结构、系统组网、频率配置的应用概况。该方案适合各大城市轨道交通无线网络广泛应用。

Metro wireless communication system is an indispen- sable communication tool for special goals, it provides a safe communication channel for train dispatch. Together with the development of metro, wireless communication network is de- veloping quickly, but the frequency assignment remains a scarce resource. The application of 800 MHz Tetra digital tnmked wireless communication in network structure, its fre- quency assignment in Shanghai metro networking are de- scribed, this scheme could be used as a generalized wireless communication in other Chinese metropolis.
