Abstract: A device and method for active scanning are disclosed. The active scanning method in a wireless LAN can comprise the steps of: allowing an AP to receive a probe request frame containing an the AP identifier; determining whether the AP is a target AP or a non-target AP on the basis of the AP identifier; and performing back-off for the transmission of a probe response frame from a second interval after a first interval is terminated in a minimum channel interval when the AP is a non-target AP. Therefore, the present invention can prevent probe response frames from flooding a STA in a short period of time by distributing intervals in which probe response frames are received to the STA. In addition, the time used by the STA to perform active scanning can be reduced.
