This paper investigates the effects of scattering on the received signal at mmWave bands. Four surfaces commonly found in indoor scenarios were analyzed to determine their roughness and scattering effects on radio wave signals. The received signal energy was determined from a modified version of the Saleh Valenzuela Ultrawideband (SV UWB) model through simulations at frequencies of 28GHz, 73GHz and 140GHz. Results show that scattering at mmWave frequencies cannot be neglected as a propagation mechanism due to its dependence on material surface texture, grazing angle and frequency. Therefore, optimal designs and successful deployment of high performance indoor wireless networks – 5G and 6G require a good understanding of scattering effects resulting from indoor surfaces.
