Summary:To estimate communication quality of a wireless LAN without downloading a file for measurement from a communication speed measurement site.SOLUTION: A wireless LAN communication quality estimation system comprises: an information collection device which collects a frame A to be transmitted and received between a wireless LAN base station to be evaluated and subordinate wireless LAN terminals thereof, and a frame B to be transmitted and received between a wireless LAN base station not to be evaluated and subordinate wireless LAN terminals thereof, and extracts wireless information on communication quality of each wireless LAN base station from a header of each frame A, B; and a wireless LAN communication quality estimation device which acquires information on the number of connected wireless LAN terminals currently connected from the wireless LAN base station to be evaluated and acquires wireless information on communication quality of each wireless LAN base station from the information collection device, and analyzes the acquired wireless information to thereby estimate right and wrong of communication quality in a wireless LAN base station to be evaluated.SELECTED DRAWING: Figure 1 【課題】通信速度計測サイトから計測用ファイルをダウンロードすることなく、無線ＬＡＮの通信品質を推定する。【解決手段】評価対象の無線ＬＡＮ基地局とその配下の無線ＬＡＮ端末との間で送受信されるフレームＡと、非評価対象の無線ＬＡＮ基地局とその配下の無線ＬＡＮ端末との間で送受信されるフレームＢを収集し、各フレームＡ，Ｂのヘッダから各無線ＬＡＮ基地局の通信品質に関する無線情報を取り出す情報収集装置と、評価対象の無線ＬＡＮ基地局から現在接続している無線ＬＡＮ端末の接続台数の情報と、情報収集装置から各無線ＬＡＮ基地局の通信品質に関する無線情報を取得し、当該情報を解析して評価対象の無線ＬＡＮ基地局における通信品質の良否を推定する無線ＬＡＮ通信品質推定装置とを備える。【選択図】 図１
