Improving indoor localization within corridors by UHF active tags placement analysis

When deploying emitting beacons, here UHF active RFID Tags, a critical issue is where the emitters should be placed, yet too few studies on this topic have been carried out. This paper focuses on the placement of the tags in order to improve the accuracy in the position estimation. This work presents a statistical study of tags positions and gives correlation between their positioning and the localization system accuracy. Guidelines are given for the tags placement in order to increase accuracy in the context of trilateration based location architecture within a hallway.
