Abstract
In this paper we study a fingerprinting-based multi-storey indoor positioning system using Received Signal Strength (RSS) measurements. The presented system analysis is based on an extensive measurement campaign including 6 large multi-storey buildings from two different European countries. First, RSS measurement statistics at two different frequency bands, 2.4 GHz and 5 GHz, are compared. The RSS statistics are studied especially from the positioning point of view, including both floor-wise and inter-floor radio propagation analysis. Based on the obtained results, it is shown that the RSS measurements at the 5 GHz band have significantly higher propagation losses especially in the vertical direction compared to the measurements at the 2.4 GHz band. The difference of positioning performance between the 2.4 GHz and 5 GHz bands is then studied as the average 3D positioning error and the floor detection probability and results are provided separately for each considered building. The results imply that the positioning performance at the 2.4 GHz is still considerably better compared to the 5 GHz band, but with possible coverage improvements in the future, the 5 GHz band seems to suit well for the positioning purposes.
