Popis:	In this paper it considers using the built-in Bluetooth in the cellphone as the positioning device; it is able from the measured received signal strength indication strength to locate the target or the cellphone position. From experimental measurements using Bluetooth positioning technique in various environments we measure signal fading condition and propose signal fading model; three-point localization method is then developed to determine potential target locations. Two specific processes, one is the introduction of weighting factors for the potential target locations and the other is to generate more test points, are then exploited to determine the target final location. With these two specific processes it is possible by using Bluetooth technique to reduce the distance determination error down to 1 m range.
