Abstract


This paper describes the implementation of an indoor propagation prediction model, based in the semiempirical model of K. W. Cheung, J. H. M. Sau, y R. D. Murch, which includes the Path Loss, the incidental angle over walls and the associated attenuation, and the Fresnel zones.

The information about the specific environment are taken from a DXF file, that must follow an established format. The attenuation factor of walls and the AP location are obtained from the user.

Also, a shadowing algorithm that optimize the simulation time is developed. Finally, the contrast of the simulation results against the data of a site survey is showed.
