    This research work outlines a study of indoor propagation environment. The electrical engineering department building at SKIKDA university was taken as a model; it was designed and executed using the properties provided by the indoor simulation software “Wireless Insite”. The study was performed at 2.4GHz, 5.2GHz and 30 GHz. Indoor propagation models must take into account obstructions inside the targeted building, the locations of access points, in addition to reflection, diffraction and scattering. However, study of the characteristics of multipath propagation based on parameters of delay propagation, path losses and received power RSS was carried out. Effects of building materials were taken into account by calculating the actual values of permeability and conductivity of each material. The results obtained for different parameters and cases show that the positioning of sensors, thickness and type of material of the walls, play a major role in the selection of the coverage range for indoor communication, another fundamental consideration was related to the specification of the transmitter antenna such as frequency, polarization, selection of an appropriate E and H plane and orientation of the antenna.
