TL;DR:
3-D Kriging interpolation technique provides significantly better radio maps when compared with an approach that assumes perfect knowledge of path loss, and the root-mean-square error of the signal power prediction achieved by the proposed 3-D Kriging method is notably lower compared to that of the perfect path loss-based prediction.
