摘要
从数字集群通信建设情况切入,选取国内在轨道交通广泛应用的窄带数字集群通信系统(TETRA体制)和宽带数字集群通信系统(TD-LTE技术),对两种方式的系统特性、建设应用情况进行归纳总结,并结合轨道交通行业现状和业务需求,详细对比两者技术参数和支持业务的能力。对宽带数字集群通信系统在国内轨道交通的发展现状做出分析总结,展望宽带数字集群通信系统在国内外的发展前景,为轨道交通无线通信的发展提供参考。
From the perspective of the construction of digitally-trunked communication, this paper aims to analyze the application and system performance of TETRA and TD-LTE, the two most popular systems that are widely used in the domestic rail transit industry. In addition, the paper shows the comparison of the technical parameters and business supportive capabilities of the two skills concerning current demand within the rail transit industry. Finally, the paper predicts the worldwide prospect of the development of TETRA and TD-LTE, which is particularly instructive to the future of rail transit wireless communication.
