• Sommario/riassunto: "Fueled by government-mandated spectrum sharing, the scarcity of unused spectrum, and the exorbitant cost of commercial spectrum licensing, wireless coexistence has become an increasingly important topic for researchers and developers of any devices or applications relying on wireless links to exchange information. Recent advances in machine learning and artificial intelligence are now being applied to wireless technology which could enable developers to significantly increase performance and quality of service under shared spectrum conditions."--
