Abstract The formation of the service cell of the wireless local area network inside the building is the result of a joint action of several of the main mechanisms of radio waves multipath propagation: reflection, refraction, diffraction, diffusion. The modeling of the rays passing through walls and floors is carried out with the purpose of the analysis of WLAN signals propagation direction in premises adjacent to the place of the access point location. The surfaces of the building structural elements are approximated by planes. The refraction of rays is considered in the approximation of geometrical optics. The algorithm for constructing the trajectory of the double refraction beam in the case of the predefined positions of the access points and client network are designed. The procedure of constructing three-dimensional route is based on calculation of the ray intersection points coordinates with the first and second refraction surfaces, for which solved by a system of nonlinear algebraic equations in vector form. Examples of ray trajectories and the estimated dimensions of areas that contain the point of refraction, in the typical for the interior cases are given.
