Experimental Evaluation of Over-the-rooftop Propagation Loss Prediction Model for the Spectrum Sharing at 26 GHz Band

Due to the scarcity of the frequency spectrum for 5G, the incumbent systems are expected to share the spectrum with 5G systems especially for those operating within the band assigned by Radio Regulations of International Telecommunication Union. For the spectrum sharing between fixed wireless access and 5G at 26 GHz band, the authors have proposed a simple prediction method of the propagation loss, which considers only the over-the-rooftop path and uniform theory of diffraction for multiple edges covering the transition zone. This paper presents the evaluation of the error of the proposed prediction model by comparing with the results of measurement campaign in the urban area.
