Indoor WiFi Positioning
- 875 Downloads
This chapter studies WiFi based wireless positioning in complex indoor environments. WiFi positioning makes use of the infrastructure (WiFi access points) widely deployed in indoor environments such as office buildings, teaching buildings, hospitals, and shopping centers. It is also a fact that WiFi technology has been adopted in billions of electronic devices such as smartphones. Although WiFi positioning is cost-effective, it suffers the drawback of low positioning accuracy and hence innovative techniques are required to enhance WiFi positioning accuracy.
