Résumé / Abstract
ERRAC (European Rail Research Advisory Council) envisioned safety and security targets for 2020 depends greatly on research into future traffic management systems. These traffic management systems make use of specific railway communication technologies and architectures. Although traditionally narrowband technologies have successfully supported these signalling and train control systems, nowadays, richer traffic management systems, and consequently safer, are expected through the use of new emerging communication technologies. The proposed work here introduced is a simulation comparison study of two 4G technologies architectures (IEEE802.16 and LTE) for railway services. The simulation tool used is OPnet, a general purpose network simulator. Railway services such as voice and video services are included in the study. The simulation results indicate that the technologies analyzed met comfortably the requirements demanded by the current key performance indicators for real-time applications. Therefore, a new set of requirements can be designed in order to envision new safety-oriented applications for the railway environment.
