Abstract: A synchronization method of a femtocell base station built in a specialized network includes searching for at least one neighboring base station by scanning signals in a second frequency band different from a first frequency band allocated for the specialized network, determining a reference base station for synchronization from among the at least one neighboring base station, analyzing the signal transmitted from the reference base station to detect start timing of a time division duplex (TDD) radio frame, and finely adjusting the start timing using a delay time corresponding to a distance from the reference base station.

Abstract: 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.

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.

Abstract: 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.

Abstract: 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.
