A location algorithm based on radio propagation modeling for indoor wireless local area networks

This paper presents a location algorithm for indoor wireless local area networks (LANs) that is based on the signal-to-noise ratio (SNR) and a radio propagation model. The proposed radio propagation modeling approach reduces the number of training data points with no significant degradation in the location accuracy, as compared to the conventional empirical method. Experimental results obtained from an indoor wireless LAN are given to demonstrate its effectiveness.
