MM-wave frequency bands at around 27 and 38 GHz have been recently allocated to 5G communications and therefore the characterization of transmission, reflection and scattering characteristics of building materials at those frequencies is in the spotlight. Scattering from common construction materials is analysed in the paper through both directional measurements and simulations. Differently from common sentiment, it is shown that 27 GHz waves can penetrate into walls and scattering from internal structures can be relevant, especially in the case of Gypsum board dividing walls. It is shown that back-scattering can be modelled with the double lobe version of the Effective Roughness model for 3 very common construction materials, with different parameters depending on the material.
