All the new rail transit lines in Beijing have used the LTE-M system for comprehensive bearing of data and cluster services.In the case where the two lines use a shared yard section,frequency interference becomes inevitable.To ensure the overall reliability of the LTE-M system,this paper describes the service scenarios at the rolling stock depot and analyzes the frequency use of the LTE-M system in scenario of shared yard section.On this basis,it summarizes the principles of 1.8 G frequency use for shared yard section,which improves the reliability of vehicle-ground communication,and provides reference for the frequency planning of the LTE-M system for shared yard sections.
