The SECOMS broadband satellite network in the multimedia services and multi-environment coverage scenario

Providing multimedia services is one of the major key issues in the world of telecommunications. If mobility and ubiquity is required, the satellite assumes an essential role due to its flexibility and to the possibility of global coverage. The paper briefly describes the SECOMS satellite system aiming at providing multimedia services to ubiquitous and mobile users. This will be fully addressed in a wide range of environments, from the open country to heavily dense cities and built-up areas as well as the indoor environment. The possibility to create a global broadband mobile communication system consisting of multiple system components with different characteristics will be investigated
