Radio propagation modeling distinguishes between small-scale fading and large-scale shadowing to characterize signal attenuation in cellular systems based on distance and environmental obstruction. Small-scale models treat rapid multipath fluctuations around a mean value as random variables distributed Rayleigh or Rician, while large-scale models describe the local average power decay over significant distances using Log-Normal Shadowing with a path loss exponent $n$ greater than two for obstructed environments. These frameworks provide the theoretical basis for link budget analysis and cell site planning within wireless communications engineering by predicting received signal strength across varying propagation mechanisms such as reflection, diffraction, and scattering.
