PURPOSE: A method for controlling a transmission output of a WLAN(Wireless LAN) is provided to dynamically control a WLAN transmission output in consideration of an RSSI, wireless link quality, and wireless link instability, thereby reducing power consumption of a wireless LAN module. CONSTITUTION: A system calculates a wireless environment measurement value that shows a current WLAN environment as a number, by using an RSSI and link quality(S310,S311). The system repeatedly carries out the steps 'S310,S311', and stores the calculated wireless environment measurement value(S312). The system calculates an average of the wireless environment measurement value from a current time, and calculates a wireless environment reference value(S314). The system calculates a transmission output power corresponding to the calculated wireless environment reference value(S315,S316). The system applies the calculated transmission output power to a current transmission output power(S317). |
