| Abstract: | Railway communication synchronization network can be divided into network frequency syn- chronization network and temporal synchronization network. Based on the present situation of synchroniza- tion networks and problem analysis of existing network structure, equipment ageing, and coverage, put forward development planning of synchronization network in the near future. Due to higher requirements of synchronization network in future communication, the development of synchronization network in the far future is taken into consideration in the viewpoint of technology updating. |
