A received signal strength RFID-based indoor location system

Π8: Indoor Positioning System using WLAN Received Signal Strength Measurements

In this deliverable we provide the details of building an indoor positioning system using WLAN Received Signal Strength (RSS) fingerprints. The positioning system has been deployed at the premises of KIOS Research Center and follows a terminal-based-network-assisted architecture. In our case, users that carry a terminal (Tablet PC) are able to self-locate and positioning is performed entirely o...

Changes in received signals with a WLAN signal strength - based indoor localisation system

Indoor location tracking using Signal Strength Pinpoints

There have been many research efforts on location awareness in an indoor environment. Most of them rely on specialized equipment or motion detectors. This research focuses on signal strengths from WiFi transmitters and uses these signal strengths to calibrate virtual pinpoints. A pinpoint is a collection of stored signal strengths over time on a predetermined location. These pinpoints can then ...

Indoor Location Sensing with Invariant Wi-Fi Received Signal Strength Fingerprinting

A method of location fingerprinting based on the Wi-Fi received signal strength (RSS) in an indoor environment is presented. The method aims to overcome the RSS instability due to varying channel disturbances in time by introducing the concept of invariant RSS statistics. The invariant RSS statistics represent here the RSS distributions collected at individual calibration locations under minima...
