Measurement-Based Large-Scale Propagation Characterization in 5G Micro-Cells At 3.8 GHz

Abstract

Large-scale propagation characterization for multiple measurements in a micro-cell scenario is carried out at 5G frequency (3.8 GHz). Distance-based path loss is computed for routes with line-of-sight, non-line-of-sight and obstructed-line-of-sight conditions, assuming a simple power law model. Path Loss exponents are computed for the whole routes, giving an effective understanding of the propagation environment. Empirical shadowing distribution is fitted to red Gaussian and non-Gaussian probability distributions. All previous propagation parameters are also found assuming measurements with similar transmitter locations come from the same channel conditions. This assumption is tested. Finally, although frequently absent in standard channel models, and useful for statistical ensemble average approximations, stationary regions are computed for all the routes.
