Abstract: Disclosed are an active scanning method and an active scanning device. The active scanning method in a wireless LAN comprises the steps of: a second station (STA) receiving a first probe request frame which has been broadcast by a first STA; and the second STA broadcasting a second probe request frame. The second probe request frame may include a probe request frame detection field, and the probe request frame detection field may indicate that the second STA has received the first probe request frame. Accordingly, a probe response frame is broadcast to a plurality of STAs, thus simplifying a scanning procedure.
