摘要
无线通信技术的总体发展趋势是向高速化、大带宽、高安全性方向演进。上海城市轨道交通应选择基于TD-LTE(分时长期演进)技术的LTE-M(城市轨道交通用长期演进)作为今后新建线路与老线大修的无线解决方案。分析了现有上海城市轨道交通LTE-M系统在投入使用后遇到的问题,提出了优化与提升方案,并为今后上海城市轨道交通LTE-M的建设提出了规划方案。
The overall development trend of wireless communication technology is to evolve towards high speed,large bandwidth and high security.Shanghai urban rail transit should choose LTE-M(long term evolution for metro)based on TD-LTE(time-division long term evolution)technology as the wireless solution for building new lines and overhaul of old lines in the future.By analyzing the problems encountered after putting in use LTE-M system in the existing Shanghai urban rail transit,optimization and improvement scheme is put forward,as well as the planning scheme for the future construction of Shanghai urban rail transit LTE-M.
