Abstract: Wireless Communications for High-Speed Trains in US

High-speed trains, though prevalent in Europe and Asia, are not yet a reality in the US. Interests and industry engagements are growing, especially around commercial hubs close to commuter homes for alleviating commute times and cost. With support from the US Federal Railroad Administration (FRA) in the Department of Transportation (DoT), Dr. Sharif’s team has explored the design requirements, challenges, and technology capabilities for high-speed wireless communications for high-speed trains using the next-generation radio access technologies. A safe, secure, efficient and seamless train operation moving underground or over at a regular or high speed (around 300 km/h) requires reliable wireless communications. The wireless communications to support in-train passenger services, train signaling and controlling services necessitate challenging considerations regarding wireless channel conditions and communications management, especially considering movement through different terrain environments (hills, flat-rural, urban-dense, etc.) and railroad infrastructure (bridges, viaduct, tunnel). These scenarios cause difficult wireless channel conditions to manage for a train-to-ground Radio Access Networks. Dr. Sharif will discuss the technical challenges for this wireless architecture including modeling and simulations as well as insights into evaluated properties of this system.
