The evaluation of WiFi positioning in a Bluetooth and WiFi coexistence environment

An increasing number of WiFi and Bluetooth terminals, tags, and other mobile devices drives a growing demand for integration and coexistence of these two technologies. This paper gives the preliminary results of WiFi positioning in a WiFi and Bluetooth coexistence environment. The received signal strength indication is introduced as an observation applied to our WiFi positioning. Then, we present the basis of a fingerprinting approach to WiFi positioning and analyze the characters and protocols of WiFi and Bluetooth networks. Furthermore, we present the interference in the WiFi and Bluetooth coexistence environments.
