Title:
SCANNING METHOD AND SCANNING APPARATUS IN WIRELESS LAN
Document Type and Number:
WIPO Patent Application WO/2013/169072
Kind Code:
A1
Abstract:
Disclosed are a scanning method and scanning apparatus in a wireless LAN. The scanning method in a wireless LAN comprises: a step in which an access point (AP) receives a first probe request frame from a first station (STA); a step in which the AP unicasts a first probe response frame to the first STA as a response to the first probe request frame; a step in which the AP receives a second probe request frame from a second STA for a specific time interval after unicasting the first probe response frame to the first STA; and a step in which the AP broadcasts a second probe response frame as a response to the second probe request frame for a specific time interval. Thus, scanning processes can be quickly performed.
