摘要：Studies for indoor positioning system based on the FingerPrint method are increasing its importance. Improving the accuracy of FingerPrint DB using Wi-Fi AP(Access Point) can give great effects on positioning. In this paper, we analyze active Wi-Fi signal phenomena from reference AP which is accessed by multi-users. Some factors which can affect the accuracy of position are studied by comparing signal patterns in the DB and real-time active signals. We propose a modified FingerPrint DB method on both AP connection and AP disconnection which can improve performance accuracy of the positioning.
