In this paper we quantify the temporal opportunities for secondary access in radar bands. In our study, WLANs are secondary users homogeneously or heterogeneously distributed, which opportunistically access the radar spectrum. Each WLAN employs dynamic frequency selection (DFS) as a mechanism to protect the radar from interference. We also consider an interference protection mechanism based on DFS and the prediction of the radar’s antenna pattern, which is termed Temporal DFS. We have the most of the time the probability of accessing the radar band are higher when Temporal DFS is used. As a consequence, there are more active WLANs when Temporal DFS mechanism is considered compare with normal DFS mechanism. This, shows once more that by having knowledge of the primary users activity secondary users can increase the probability of accessing the spectrum and improve spectrum utilization.
