Taking into account the intrinsic material properties (i.e., complex permittivity), we strive to demonstrate a comparison between Rayleigh-Rice (R-R) approach and the real 3D surface topography parameters. The R-R approach approximates the surface deviations or topography of any rough material with Gaussian height distribution. The ray-tracing simulations are conducted in a realistic but simple office environment for line-of-sight (LoS) and non-line-of-sight (NLoS) conditions to study the multipath propagation with its impact on total received power and channel delay profile.
