Explanation

Active scanning is the method where a wireless client device broadcasts a probe request frame to all available access points. Any AP within range responds with a probe response frame containing network details (SSID, supported rates, etc.). This is in contrast to passive scanning, where the device simply listens for beacon frames that APs periodically broadcast without transmitting anything itself. Active scanning is faster but reveals the device's presence, while passive scanning is stealthier.
