Method for operating wireless LAN card in wireless LAN system

Abstract

A method for operating a wireless LAN card in a wireless LAN system. The present invention relates to the wireless LAN card operation method which is capable of receiving a beacon signal of an access point and setting a frequency band set with respect to the access point as a communication channel, in an infrastructure mode, while in an Ad-hoc mode, setting a frequency band used in common in all regions as the communication channel, thereby meeting requirements of communication standards of all countries. The wireless LAN operation method comprises the steps of registering as channels allowed in the wireless LAN card all frequency bands recommended as wireless communication channels in a wireless LAN, performing in an Ad-hoc mode an access to a target terminal via a channel 10 or a channel 11 used in common in all countries, and, in an infrastructure mode, scanning the respective frequency bands of the allowed channels to receive beacon signals, and securing a channel to communicate with an access point over the secured channel.
