摘要
基于TD-LTE宽带数字集群系统必将成为城市轨道交通无线专网的未来发展趋势。针对广州地铁的实际情况,从合理利用资源的角度,对基于1.8GHz的TD-LTE无线专网的无线带宽的分配原则和无线专网与广州地铁无线政务网的共用天馈的方案进行探讨,为基于TD-LTE宽带数字集群系统在广州地铁的应用提供依据。
The broadband digital trunking communication system based on TD-LTE will become future development trend of the wireless network special for urban rail transit. According to the actual situation of the Guangzhou metro, the wireless cial wireless network based on 1. 8GHz TD-LTE and bandwidth allocation principles of the spe- the shared antenna-feeder system between special wireless network and wireless e-government network of the Guangzhou metro are dis cussed in the perspective of rational utilization of resources, which provides some basis for the ap plication of TD-LTE broadband digital trunking communication system in Guangzhou metro.
