We evaluated the performance of the proposed WLAN positioning system using spot information. We compared the
proposed system with the conventional WLAN system without spot information.
In this evaluation, the positioning is that each user specifies his existing area on a floor in a building from many candidates.
The conventional WLAN system was consisted referred [10]. In the conventional system, the estimation of the building and
the floor is carried out using Proximity. The estimation of the area is implemented using Fingerprinting.
