R-factor and Optimal Placement of Receivers for Enhancing Location Accuracy in an RSSI System
نویسنده
چکیده
The fundamental cause of localization error in an indoor environment is fading and spreading of the radio signals due to scattering, diffraction, and reflection. This work proposes a new factor called R-factor to measure the localization error introduced by a receiver in a real-time location determination system (RTLS). Additionally, R-factor is shown to be reduced by using antenna or frequency diversity. Finally, R-factor is used to compute the optimal placement of receivers on the target area.
