    Abstract: Embodiments herein describe a group of APs (115A-115D) that uses a shared radar cache (120A) to select a new channel after vacating a current channel when performing dynamic frequency selection (DFS). The group of APs (115A-115D) can set aside memory to store status information about the DFS channels in the frequency band. For example, when one AP detects a radar event (and has to vacate a DFS channel), the AP updates an entry for that channel in the shared radar cache (120A). The APs can also query the cache to determine a new channel after vacating its current channel. That is, the shared radar cache may store the most recent radar events occurring in a channel. In this manner, the APs can select a new channel that has little or no recent radar events, which reduces the likelihood the AP will have to vacate the new channel.
