This paper studies a multi-wall path loss propagation model for an indoor environment at 1.93 GHz of transmission frequency. The effects of locations, materials, and thickness of the walls are considered in the model. The loss factors are optimized and verified by the measurements. To implement the proposed model, image processing techniques are applied to the architectural floor plan in order to obtain the locations and thickness of the walls. Compared with the actual measurements, the proposed model provides higher accuracy in prediction of the path loss than some of the existing well-known empirical indoor channel models. To test the robustness of proposed model to the noise in the images of floor plans, four types of noise are added to the images when obtaining the locations and thickness of walls. Simulation results indicate that the performance of proposed model, unlike that of an existing model, is not degraded by the noise added to the image of floor plan.
