Communication link connection method in wireless LAN system using visible light communication

摘要

A method for connecting a communication link in a wireless LAN(Local Area Network) system using a visible light communication is provided to offer a call setting procedure of a visible light wireless LAN protocol in a wireless LAN system using a visible light communication and to arrange the communication link by enabling a user visibly to confirm the place and range of visible light. A method for connecting a communication link in a wireless LAN system using a visible light communication comprises the steps of: judging whether or not it is possible for a mobile node to receive a visible light signal which occurs at an access point(415); performing the synchronization with the access point in the mobile node and generating an indication light for arranging communication links at a visible light transmission unit of the mobile node(420); and setting up a communication link of a uplink direction by using the indication light.
