Abstract

A system and method for controlling transmit power in a wireless local area network (WLAN) are disclosed, and more particularly, a system and method for controlling transmit power in a WLAN are disclosed, which can control transmit power in a WLAN to Terminals outside the service area provide WLAN services. Therefore, link margin data of a station located at a hidden node of the WLAN is received from another station located within the service area, and the received link margin data is compared with preset link margin data, To control the transmit power in WLAN.

Description

technical field The present invention relates to a system and method for controlling transmit power in a wireless local area network (WLAN), and more particularly, to a system and method for controlling transmit power in a WLAN, which can give Terminals outside the service area provide WLAN services. Background technique A local area network (LAN) is mainly classified into a wired LAN and a wireless LAN. The biggest difference between the two LANs is the presence or absence of cables. In a wireless local area network (WLAN), communication is accomplished using radio waves rather than cables. WLANs emerged as an option to overcome the difficulties in installation, maintenance and mobility due to the use of cables. In addition, the increase in users' demand for mobility has led to an increase in the demand for WLANs. A WLAN consists of an access point (AP) and a WLAN card. An AP is a device that emits radio waves so that WLAN users within the emission distance can acce...
