Towards a wireless architecture for the deployment of next-generation services in the railway industry


This paper describes a next-generation architecture for wireless communications, based on mobile phone carriers (GPRS) and broadband (WiFi), developed for the field of railways and allowing "train-to-earth" communications. This communication channel aims to complement traditional railway communication systems and its benefits make the deployment of new services, such as passenger oriented services, possible. Moreover, the result of this work is a framework for the addition of new on-board applications that have the capacity to connect the trains with control points. In addition, some planned improvements to this framework are described. Currently, as part of the architecture's validation, new digital services in the field of railways have been developed and are being implanted, and some others are being scheduled to be developed.
