Potentials of TV and radar bands for secondary communications: Methods and approaches

This paper aims to provide quantitative assessment results for the potentials of TV and radar bands for secondary communications in terms of secondary spectrum availability. In particular, its objectives are to present the developed methods and approaches for assessment of the secondary spectrum and to provide tangible results about its availability. The paper contains results of secondary spectrum in presence of multiple secondary WiFi-like users for two real world scenarios, involving two different primary communication networks: television (TV) broadcasting system and air traffic control (ATC) radar system. Detailed secondary access scenarios and scenario-dependent assessment methodologies from our previous work are adopted and elaborated here with necessary modifications to provide an overview of the findings and to draw generalized concussions.
