WS-02: Cognitive Radios and Networks for Spectrum Coexistence of Satellite and Terrestrial Systems (CogRaN-Sat)

Organizer: Daniele Tarchi (University of Bologna, Italy)

Cognitive radio systems pose some of the most important challenges in the ICT world in terms of tackling spectrum scarcity and enabling ubiquitous broadband access. Although their application in terrestrial context has been studied in depth in the last years, their applications in satellite or hybrid satellite/terrestrial environments is still largely unexplored due to technical and regulatory issues. More specifically, in the technical domain, the wide coverage areas enabled through satellite communications limit the flexibility of spatially reusing the spectrum in conjunction with terrestrial systems. Furthermore, from a regulatory perspective, the heteroge-neous adoption of terrestrial spectrum directives by national authorities complicates the coexistence of terrestrial deployments with internationally operating satellite systems. In this direction, a holistic techno-regulatory approach is needed in order to set the foundations for engineering and deploying cognitive systems that enable the coexistence of satellite and terrestrials.
