随着我国城市轨道交通的快速发展,车地无线通信的发展已越来越不能满足日益增长的轨道交通业务发展的需求。本文通过分析当下城市轨道交通车地通信的现状,通过对移动通信相关技术原理的研究,提出了移动通信技术在城轨车地通信方面具有更稳定、更可靠的优势。合理地实现移动通信技术与城轨车地通信的结合,能够更好地实现车地无线通信传输,满足轨道交通业务的需求
With the rapid development of urban rail transit in our country, the development of wireless land-mobile communication has been increasingly unable to meet the needs of the ever-growing rail transit business. In this paper, by analyzing the current status of URT ground communication in current era and by studying the related technical principles of UMTS, it is proposed that the mobile communication technology has a more stable and reliable advantage in URWT communication. Reasonably achieve the combination of mobile communication technology and urban rail car, to better achieve the car wireless communication transmission, to meet the needs of the rail transit business
