Abstract
Disclosed is a method for scanning for an access point. An active scan method comprises the steps of: generating a probe request frame including information on the signal strength of a terminal; and transmitting the probe request frame to an access point. Thus, a waste of time and radio resources can be prevented.
Claims15
An active scan method performed at a station, the active scan method comprising:
- generating a probe request frame including signal strength information of the station;
- and
- transmitting the probe request frame to access points.
An active scan method performed at a station, the active scan method comprising:
- transmitting a probe request frame to access points;
- receiving a probe response frame corresponding to the probe request frame from a certain access point;
- acquiring information about downlink quality based on signal strength of the probe response frame;
- and
- performing an access to the certain access point if the downlink quality satisfies a predetermined standard.
