The application scenarios of railway radio communication are complex,while the existing narrowband communication such as GSM-R and radio train dispatching system fails to meet the requirements of service application development.The carrying capacity of railway 5G-R has been greatly improved,mainly for wide-area train-ground communication services such as dispatching communication,train control and train operation safety monitoring.However,for large passenger stations,freight yards,maintenance bases and other places with densely populated railway operators,it is unable to carry overall railway service applications limited by the spectrum bandwidth of 5G private networks,so it is necessary to consider various radio technologies for supplementation.This paper also elaborates the railway service application scenarios,analyzes the characteristics of radio communication technologies such as 5G mmWave and the 6th-generation wireless LAN technology(Wi-Fi6),and discusses the schemes of multi-technology convergence carrying railway 5G service applications. 展开更多
