Design and Development of an Indoor Positioning System Based on WiFi Signal Strength Mapping

Multiple indoor positioning approaches have been developed over time due to the increased business interest in indoor location-based services (ILBS). As the Global Positioning System (GPS) signal is unavailable indoors, several other signals have been introduced. Due to the widespread deployment of wireless Local Area Networks (LANs), WiFi appears as a potential option. WiFi fingerprinting, in particular, has garnered significant attention recently because it does not require a line-of- sight path between the transmitter and receiver. Therefore, it achieves promising performance in a complicated interior environment. In this paper, we proposed an Indoor Positioning System's (IPS) tracking based on WiFi fingerprinting and examined it in a house and office environments. The approach proposed in this paper may be directly implemented in office and factory environments at minimal cost using existing infrastructure to track the movement of workers for productivity monitoring.
