Method for balancing quality of wireless communication channel and wireless communication apparatus using the same
Disclosed herein are a method for balancing the quality of a wireless communication channel wherein the quality of the wireless communication channel can be more accurately estimated and adjusted on the basis of the combination of observation results of the number of data frames failed to be transmitted in the past and a received signal strength (RSS), and reliability of data transmission over the channel can thus be increased, and a wireless communication apparatus using the same. The method includes collecting information about whether data frames have been successfully transmitted and information about RSSs of the wireless communication channel, acquiring the number of data frames failed to be transmitted and an average RSS in a predetermined observation period using the collected information, comparing the acquired transmission-failed data frame number with a predetermined threshold value and the acquired average RSS with a predetermined reference RSS, respectively, and estimating the quality of the wireless communication channel and quality degradation factors in detail by performing an AND operation with respect to the comparison results. Therefore, it is possible to stably adjust the channel quality.
