In this paper the influence of a radio signal frequency on performance of Indoor Positioning System based on fingerprinting has been examined using ray-tracing simulations. It has been simulated how spatial distribution of an RF signal strength change with the signal’s frequency. The results were used to show its’ impact on the behavior of localization algorithms that are employing RSS measurements to determine node’s position in wireless sensor networks. Moreover, to give the fair comparison, instead of the overall accuracy calculation it has been proposed to determine IPS accuracy for every logical section of the scene. The proposed approach gave the expected conclusions on how the accuracy of indoor positioning systems based on RF fingerprinting algorithm depends from RF signal’s frequency in simulated area.
