In this paper, we evaluate the communication of peripheral terminals affects positioning performance in wireless LAN by experiment. In the preliminary experiments, it is confirmed that the scan of the access points(AP) varies depending on the time period, and the communication of peripheral terminals affects the scan of the AP. The based on preliminary experiments, we evaluate positioning performance of wireless LAN in cases where the communication status of peripheral terminals is different. From the positioning experiment, when constructing the database(DB) of the wireless LAN positioning system, it is better the situation only when there is no communication than the case of configuring only the situation in which communication is being conducted. It shows that the distance error decreases. In addition, it is suggested that including a few percent of the data only the situation in which communication is being conducted for the DB composed only of the data not in the situation of communication, the distance error becomes further smaller There.
