High accuracy indoor localization: A WiFi-based approach | IEEE Conference Publication | IEEE Xplore
Wireless indoor positioning systems (IPS) have become popular recently. It spawns a lot of location-based applications, such as personalized advertisement in a grocery store, tourist guidance in a museum, and goods localization in a warehouse, to name a few. Speaking of outdoor localization systems, Global Positioning System (GPS) has provided routes to millions of drivers for years. However, the GPS signal could be too weak when it comes to indoor localization: the blocking of concrete walls and floors severely attenuates the signal. On the other hand, the precision in the order of tens of meters is far from satisfactory for indoor applications. Realizing these drawbacks, many researchers and companies harness the ubiquitous wireless local area networks (WLAN) powered by WiFi technology. Received Signal Strength Indicator (RSSI) is a MAC layer, coarse-grained information available in mainstream wireless network interface controllers (NIC) [1]. Thus, RSSI-based IPS have been well studi

IPS based on Received Signal Strength Indicator (RSSI) could only achieve a precision of several meters due to the strong temporal and spatial variation of indoor environment. On the other hand, IPS based on Channel…
