Research on 5G Key Technologies and Applications in Urban Rail Transit

With the rapid development of science and technology, Chinese urban rail transit has entered a newstage of intelligent development from the stage of rapid construction. Urban rail transit has the advantagesof high speed, large capacity and high density, which greatly facilitates modern life. However,urban rail transit is quite different from conventional ground transportation. Traditional informationtransmission methods cannot be well applied to urban rail transit. The maturity and commercial useof 5G mobile communication technology provide new ideas for solving the problem of informationtransmission in urban rail transit. Based on the salient features and key technologies of 5G communicationtechnology, this paper researches on key technonlgies 5G in rail transit scenarios to achievefast and efficient processing efficiency. It is a solution for intelligent operation and maintenance ofurban rail transit and high-definition video surveillance, and studies and analyzes the security of thesystem solution. This fills the gap of rail transit in these two fields, and provides dual guarantees ofsafety and service for urban rail transit construction. It provides a new direction for the applicationof future urban rail transit system.
