Indoor positioning system using WLAN channel estimates as fingerprints for mobile devices
Erick Schmidt, David Akopian
With the growing integration of location based services (LBS) such as GPS in mobile devices, indoor position systems (IPS) have become an important role for research. There are sev…
A Fast-rate WLAN Measurement Tool for Improved Miss-rate in Indoor Navigation
Erick Schmidt, David Akopian
Recently, location-based services (LBS) have steered attention to indoor positioning systems (IPS). WLAN-based IPSs relying on received signal strength (RSS) measurements such as f…
Fast prototyping of an SDR WLAN 802.11b receiver for an indoor positioning system
Erick Schmidt, David Akopian
Indoor positioning systems (IPS) are emerging technologies due to an increasing popularity and demand in location based service (LBS). Because traditional positioning systems such…
