摘要:
针对北京地铁实际运营中出现的车地通信问题,阐述了车地通信应用现状和业务需求,选取了典型试验段设计并搭建了LTE-M(地铁长期演进)系统,通过动态测试与分析,验证了在10 MHz及20 MHz频宽时LTE-M系统的基本性能和承载能力,并提出了应用建议。
Abstracts:
Targeting the problems existing in vehicle-wayside communication in the actual operation of Beijing Metro, the application status and business requirements of vehicle-wayside communication are expounded. A typical test section is selected to design and build an LTE-M (long-term evolution metro) system. Through dynamic testing and analysis, it is verified that the basic performance and carrying capacity of the LTE-M system in the 10 MHz and 20 MHz bandwidths are presented, corresponding application suggestions are put forward.
