Read moreCategory: Radio Spectrum
The increasing mobile devices and wireless applications have created unprecedented demand for radio spectrum. The fixed radio spectrum allocation policy commonly adopted today cannot not meet this demand. This sections seeks the state-of-the-art research and development on both theoretical contributions (including new models, architectures, protocols, tools, concepts, and analyses) and practical contributions (including new techniques, prototypes, deployment, system experiments, and new applications) on enabling efficient spectrum co-access between licensed users and unlicensed users.
