1. A wireless LAN communication quality estimation system configured to estimate communication quality of a wireless LAN base station that is an evaluation target, by using radio information on the wireless LAN base station that is the evaluation target and a wireless LAN base station that is a non-evaluation target, the wireless LAN communication quality estimation system comprising:
an information collecting device configured to collect a frame A transmitted and received between the wireless LAN base station that is the evaluation target and a wireless LAN terminal subordinate to the wireless LAN base station that is the evaluation target and a frame B transmitted and received between the wireless LAN base station that is the non-evaluation target and a wireless LAN terminal subordinate to the wireless LAN base station that is the non-evaluation target, and extract the radio information on communication quality of each of the wireless LAN base stations from a header of a corresponding one of the frames A and B; and
a wireless LAN communication quality estimation device configured to acquire, from the wireless LAN base station that is the evaluation target, information on a number of currently connected wireless LAN terminals, acquire, from the information collecting device, the radio information on the communication quality of each of the wireless LAN base stations, and analyze the information to estimate whether the communication quality of the wireless LAN base station that is the evaluation target is good or bad.
