Research on Urban Rail Transit 5G Public-private Network Wireless Coverage Scheme

Abstract

Objective The urban rail transit 5G public-private network (PPN) is a vertical application of 5G public network in urban rail transit industry, which differs significantly from the wireless coverage scheme of the 5G public network when only catering to the communication needs of the general public passengers. Therefore, it is necessary to study the wireless coverage scheme for urban rail transit 5G PPN. Method Based on the wireless communication service requirements of urban rail transit, considering its complex application environment, the wireless coverage range of the 5G PPN for urban rail transit is defined, and different requirements of wireless coverage technology index are proposed for various application scenarios. Different wireless coverage methods for tunnel areas, ground areas, and indoor areas are designed, and optimization measures for wireless network capacity and coverage are explored. Result & Conclusion The formed urban rail transit 5G PPN wireless coverage scheme, oriented towards service requirements, is a comprehensive and continuous solution for all scenarios. The scheme should also consider the coordination of different operator standards, multi-frequency band wireless system co-construction and sharing, and interference between systems to provide urban rail transit users with reliable 5G PPN services.
