Abstract:	We analyze a statistical characteristic of Wi-Fi RSSI difference from heterogeneous devices and propose its normal distributed model for cancelling the effect of the diversity of devices on Wi-Fi AP’s RSSI measurements. To evaluate the accuracy enhancement of Wi-Fi AP position through Wi-Fi RSSI difference correction, four devices with different Wi-Fi chipsets are used to collect measurements in a small-scale testbed. As a result, the correction can normalize Wi-Fi RSSI measurements from heterogeneous devices into Wi-Fi RSSI measurements from a reference device so that the quick and accurate survey is achievable by using multiple devices in wide indoor area. Furthermore, user generated contribution, which uses heterogeneous devices, can be easily applied to the Wi-Fi AP position estimation by using this correction.
