Research And Design Of Mobile Communication System For Rail Transit In The High-speed Scenes

With the development of Shanghai Economic and Social, the totaltraffic demand is showing a trend of rapid, sustained growth of urban railtransit. Shanghai Rail Transit (also known as Shanghai Metro) alreadyhas11operating lines (excluding the maglev line). It's the world's longesturban rail transit system.Research and design wireless networks and mobile communicationsfor Shanghai Metro can improve the quality of communications networks,to meet customers' quality communications needs of the environment, italso increased the traffic and operating profit, which has a good socialand economic benefits.Subject to rail transport special communication scene, in order tomeet the communication needs of the particular scene, effectivelyimprove the quality of communication for the purpose of the11railtransit as an experimental object, its wireless coverage, networking,wireless optimization and maintenance relevant research to the privatenetwork covering the design requirements of the subway communication.Topics will study the content and outcome of application in Shanghai RailTransit, through the development of optimization strategies and parametercharacteristics of the subway scene, the multi-faceted road test examinedthe results of the research.The contents of the profile of this study includes the rail transportcharacteristics of the mobile communication system, networking,optimization and maintenance, research is focused on rail transport underhigh-density high-speed scene to cover the design and special networknetworking implementation strategy. The difficulty of this study is not yetan effective model to guide the high-density high-speed subway scenewireless coverage, more country and the world were not such a huge railtransport of wireless communication systems, the factors to be consideredin the design and network implementation. This research method can be combined with the actual situationapplied to different environments, test results show that the researchresults for the high-density high-speed mobile communication scenarioscovering the construction of instructive, practical and effective.
