An Indoor Positioning System with Bluetooth Network

Abstract

There are strong needs for indoor positioning system in industries and businesses. This paper presents indoor positioning system utilizing received signal strength indication (RSSI) of Bluetooth wireless communication. Propagation loss caused by metallic objects and its effect on measurement error is discussed. A positioning system simulator was developed using this propagation loss model. This simulator enables efficient base station placements, and evaluation of position correction algorithm that uses base–station–to–base–station communication.
