In this paper, the main concepts of the Wireless Infrastructure over Satellite for Emergency COMmunications project (WISECOM) are presented. These concepts rely upon the idea of a light and rapidly deployable system that can be autonomously used in remote areas where telecommunication networks have broken down to provide access to emergency telecommunication services using a large set of wide-spread telecommunication technologies such as GSM, UMTS, WiFi, WiMAX, and TETRA and a satellite back-hauling link. In the paper, a detailed description of the whole WISECOM system is provided, with emphasis on the WISECOM Access Terminal, the unit deployed on the disaster area and interfacing the selected satellite system to different wireless local access technologies. Then, three relevant and realistic examples of configuration of the WISECOM system (GSM, UMTS and TETRA over satellite) are detailed.
