  • METHOD AND APPARATUS FOR EVALUATING AN AIR INTERFACE CONDITION OF A WLAN
    Publication number: 20130223273
    Abstract: In a method and an apparatus for evaluating air interface condition of a wireless local area network (WLAN), the evaluation of the air interface condition of the WLAN is divided into four layers: the evaluation of the air interface condition of the pre-defined area, the evaluation of the air interface condition of each place in the pre-defined area, the evaluation of the air interface condition of each AP in each place and the evaluation of the air interface condition of each user accessing each AP. The method and apparatus are able to provide definite evaluation denoting the level of the air interface condition through analyzing and quantizing of the statistical information items with respect to the overall air interface condition of the whole area covered by the WLAN or the partial air interface condition of each place, each AP and each user in the pre-defined area.
