Abstract
A method for designing and analyzing a wireless network located at terrestrial environments by using a method based on an algorithm utilizing a 3D stochastic multi-parametric (3DSM) model of a terrain area designated for the wireless network. The algorithm is used for designing a wireless network operable in the area and analyzing the performance of the wireless network. The 3D model methodology is applicable for calculating average field intensity in different outdoor environments which is derived for a three-dimensional geometry model and yields higher precision calculations for the mixed residential or sub-urban areas by considering the wide range of vertical and horizontal dimensions of houses and trees.
