Scattering Effect up to 100 GHz Band for 6G

This paper clarifies frequency dependency of scattering effects from the building rough surface up to the 100 GHz band for 6G. From the measurements, it is found that the scattering are diffused as the frequency increases. Based on these results, we modeled scattering using directive scattering model and confirmed that the frequency dependency of the scattering can be predicted by changing the beam width of the directive scattering model according to the frequency.
