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

Abstract

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