Abstract

A wireless LAN system and a method of using the same. The wireless LAN system includes at least one Interface Service Commercial module (ISCM) for collecting and transferring channel information related to channels in use for wireless networks located in a neighboring area; and an Access Point (AP) having a module for adjusting an established channel to a different frequency band channel based on a comparison result of the transferred channel information and the currently established channel. Accordingly, the wireless LAN system prevents crosstalk and interference with different LAN systems existing in a neighboring area to improve the efficiency of a wireless LAN system.

Claims

1. A wireless LAN system, comprising:

at least one of wireless devices for collecting and transferring channel information related to used channels in use for wireless networks located in neighboring areas; and

an Access Point (AP) having a first module for comparing a first established channel with the channel information and adjusting the first established channel to a second established channel at a different frequency band channel if the first established channel is not spaced apart from each of the used channels for the wireless networks by more than a certain number of channels,

wherein the AP adjusts the first established channel to be spaced apart by more than 4 channels from each of the used channels in use for the wireless networks,

wherein the wireless devices are wireless LAN stations, each of the wireless LAN stations comprising a module for searching and transferring the channel information to the AP,

wherein the at least one of the wireless devices transfers the channel information to the AP through a wired network, and

wherein the wireless devices are Inter-Space Channel Monitors (ISCMs).

2. A method of using wireless LAN systems, comprising:

collecting and transferring channel information related to used channels in use for wireless networks located in neighboring areas;

comparing a first established channel for an Access Point (AP) with the channel information; and

adjusting the first established channel to a second established channel at a different frequency band channel if the first established channel is not spaced apart from each of the used channels for the wireless networks by more than a certain number of channels,

wherein the adjusting the first established channel comprises adjusting the first established channel to be spaced apart by more than 4 channels from the used channels in use for the wireless networks,

wherein the transferring the channel information is performed by a wireless LAN station, the wireless LAN station comprising a module for searching and transferring the channel information to the AP,

wherein the transferring the channel information transfers the channel information through a wired network, and

wherein the wireless devices are Inter-Space Channel Monitors (ISCMs).
