In this paper we propose a deterministic approach to model the radio propagation channels in complex environments. In this technique we divide the environment into small and equal rectangular cells. Each box can have its own permittivity and conductivity. The simulation is based on geometric optics and uses ray launching and ray tracing techniques. The information needed to reconstruct the field strength pattern inside each cell, such as the angle, distance from source and polarization of each ray, are calculated on the boundary of every cell. The effects of all rectangular obstacles, such as walls, doors, columns, and so on, are considered by the model. Both reflection and refraction effects are taken into account. Simulation results are presented and the reliability of these results is examined by comparing them with those obtained from measurements at 60 GHz. We also show that it is possible to minimise the simulation time of the model by an appropriate choice of cell size.
