This paper describes the work done during the last 3 years in the field of wireless communications for the railway industry. Specifically illustrates the strategy followed for the management of broadband wireless communications in a hybrid network (mobile/radio). This management allows the optimization of both bandwidth and transmission rate of the applications deployed in the ground control stations ('earth' applications) and on-board systems (train applications). It also describes the general aspects of a ‘train-to-earth’ communications architecture, which allows an easy and standard integration of applications and services both new and legacy.
