Operation System (OS) Scan: The supplicant configures SSID (usually ANY) and the WLAN driver performs a one-shot scan on all allowed channels (according to the regulatory domain) in all relevant bands according to the configured SSID.
This scan is typically used for a site survey by the graphical user interface (GUI), using the supplicant’s control interface.
