Wireless localization techniques based on received signal strength require highly accurate prediction of path loss. This has led to revisit existing breakpoint distance models for path loss prediction. Dual-slope path loss models for line-of-sight propagation have been verified by many measurement campaigns. Breakpoint distance is the distance that separates the two different trends in path loss levels. Many prediction breakpoint distance models have already been proposed in literature. Perera's breakpoint distance model has been verified with some of the published measurement results. In this work, we provide correction terms for ground and water reflection surfaces for both horizontal and vertical polarization. The correction terms generalize application of Perera's model in terms of applicability ranges and RF propagation scenarios. The correction terms are based on analyzing and modeling of extracted patterns of prediction error.
