1A2-F19 Localization of Mobile Wireless Client in Multistory Environment using Received Signal Strength from Wireless LAN Access Points

Abstract

This paper proposes a method for localization of a mobile wireless client, such as smart mobile phone, in a multistory building using strength of received signals from wireless LAN access points. This method uses public wireless LAN access points which are settled three-dimensionally in the building. The method supposes that humans and robots do not change height of the mobile client on each floor in the building when they move the mobile clients. The position of the mobile client on the floor and the floor number in the building are estimated simultaneously. Experimental results show feasibility of the proposed method.
