A model for radio propagation loss prediction in buildings using wide-angle parabolic equations

This paper propose a model to calculate the path loss propagation in an indoor environment using parabolic equations. To solve the parabolic equation a mixed Fourier transform was used. The impedance boundary conditions, wide-angle relative to paraxial direction of propagation and complex refractive index for the medium were considered. A campaign of measurements was carried out in two environments in 900 MHz and 2.4 GHz frequencies. Simulations with the proposed model showed good agreement with the experimental data and with model of UWB Propagation Channels.
