This paper describes the work that is currently performed in the European FP7 project “A Holistic Approach Toward the Development of the First Responder of the Future”, that is funded by the European Commission under its Security Program. This work aims at providing an overview of a novel emergency network architecture. It represents a complete suite of real-time communication technologies exploitable to support the first responders with information services during disaster events. More specifically, this work will investigate the system architecture, in terms of network structure, the provided communication services, the available technologies and how the recommended solutions will be really implemented.
