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。
Abstracts:
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.
