The one-shot scan is a general name for non-periodic scan types.
Application Scan: The application configures all scan parameters, including the channel list and scan type (active or passive).
| Application Scan | |
|---|---|
| Parameters | |
| Scan type | Passive or active |
| SSID | ANY or specific |
| BSSID | ANY or specific, per channel |
| Band and Channel list | Up to 16 channel |
| Dwell time | Min, max per channel |
| Early termination conditions | Per channel |
| Scan logic | |
| Firmware to scan the list of channels | |
| Scan Results | |
| Firmware filters according to SSID and BSSID parameter | |
| Driver accumulates results during scan process | |
| Driver issues scan complete to application | |
| Driver provides API to read the results of scan (accumulated, with aging) | |
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.
