C12: Communications Technologies for (high-speed) transportation systems (2)

Saturday, August 23  09:40-10:40,  Room #20

Session Chairs: Marion BERBINEAU, David Matolak

To increase quality, reliability, safety and security of Railway systems (underground, conventional trains and High speed trains) while increasing accessibility and productivity, modern railway operations rely on ever increasing fluxes of information between operatorsí staff workstations, central databases and field devices widely distributed by the trackside and on board the train. This trend is accentuated by the development of automatic train control systems and driverless systems. The communications applications required in the railway domain are: safety-related services such as control and command, and non-safety related services such as passenger information, video surveillance, and internet on-board trains. Robustness, reliability, high data rate, spectral efficiency, optimization of radio resource usages are of significant interest for railway applications. Evaluating the performance of railway radio systems requires radio channel models for numerous propagation environments: rural areas, urban areas, tunnels, fast fading, Doppler effects, tunnels, cuttings, viaducts and electromagnetic interferences. Furthermore, dedicated antennas need be developed with adequate performance and placement. Security, robustness, throughput and latency are also strong requirements. The session will present the new results addressing these challenges.
