This book offers the reader the keys for a successful understanding, integration and usage of satellite systems in addition to next generation terrestrial networks. The DVB-S2/RCS system is used to illustrate the integration challenges. The presentation uses a system approach, i.e. it tackles the terrestrial and satellite telecommunication systems' complexity with a high level approach, focusing on the systems' components and on their interactions. Several scenarios present the different paths that can be followed for the integration of satellite systems in terrestrial networks. Quality of…mehr
