The disclosure relates to a wireless LAN and, more specifically, to a method and device for pairing a client device and an access point. According to one aspect of the invention, there is provided a pairing method executed at a client device side so as to be paired with an access point. The pairing method includes: transmitting a first probe request including probe request type information to the access point; receiving a first probe response from the access point; and performing an authentication procedure in conjunction with the access point on the basis of the first probe response.

Method and apparatus for pairing client device and access point in wireless LAN

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.

The device for controlling a wireless access point comprises: a grouping unit which groups wireless access points which use the same channel, by using channel use information received from the wireless access points; a map generator which computes each received signal strength value of the grouped wireless access points and each output strength value of the grouped wireless access points; an extractor which extracts a wireless access point having the highest received signal strength value among the grouped wireless access points, if interference occurs between said grouped wireless access points; and an optimal output strength value-calculator which computes a corrected output strength value by using the received signal strength value of the extracted wireless access point, a threshold value of predetermined received signal strength, and a currently used output strength value between said grouped wireless access points.

Wireless access point and method and device for controlling wireless access point

An apparatus for wireless relaying comprises: a transmission unit for generating a wireless signal; an amplification unit for amplifying and outputting the wireless signal; a conversion unit for converting the wireless signal into a digital signal; and an adjustment unit for adjusting the amplification ratio of the amplifying unit so that the difference between an output level value of the digital signal and a predetermined target power is lower than a predetermined numerical value.
