ABSTRACT

At present, urban railway system has developed rapidly meanwhile train safety has become one of the most important issues. The vehicle-ground communication system is evidently one of the important systems to ensure the safety and stability of urban railway system. However, the current mainstream WLAN technology is difficult to meet the technical requirements for vehicle-ground communication of current urban railway system due to the influence of bandwidth, speed, external environment and other factors, so it is necessary to explore a new technology to better meet the vehicle-ground communication system. Therefore, this paper analyzes the advantages of LTE technology and its application in urban railway system by comparing LTE technology with WLAN technology.
