Zusammenfassung:A Wi-Fi system includes a plurality of access points each configured to operate on a plurality of channels including Dynamic Frequency Selection (DFS) frequency channels and non-DFS frequency channels; and at least one access point of the plurality of access points is connected to a controller, wherein the controller is configured to coordinate usage of the plurality of channels between the plurality of access points including usage of the DFS frequency channels pursuant to predetermined DFS rules. One or more access points of the plurality of access points are configured to perform DFS measurements for a Channel Availability Check (CAC) and the DFS measurements are provided to the controller.
