This article compares slow fading component of the propagation loss calculated through parabolic wave equation and some models of the literature with results obtained during measurement campaign, in indoor environment. The frequency used was 850 MHz; a complex refractive index was considered. The implicit finite difference scheme of the Crank‐Nicolson type was applied in order to get the solution of the parabolic equation. The propagation was considered in 15° with direction paraxial. © 2007 Wiley Periodicals, Inc.
