چکیده

The FingerPrint positioning method is known as a superior method in indoor positioning system that maintains previous signal strength patterns and compares with the measured new real-time signals on APs. In this paper, we analyze active signal phenomena using multi-rate Wi-Fi signals from reference AP which is accessed by multi-users. Some important factors which can effect to the accuracy by comparison among previous signal patterns in the DB and real-time active signals are studied. Some interesting phenomena based on AP connection and disconnection signals are observed.
