Summary: | A simple approach of path-loss and root-mean-square (rms) delay spread prediction for indoor propagation environment is developed based on the room electromagnetics theory. The indoor room environment is interpreted as a lossy cavity, which is characterized by the diffuse scattering components caused by the walls and surrounding obstacles, and a possible line-of-sight component. Simply, speed of the algorithm and good accuracy are among the advantages of this approach. To apply the method, it only requires the knowledge of the dimensions of the room and the reverberation time, which can be easily obtained from one measurement of the power-delay-profile in the investigated environment. For experimental validation, path-loss measurements at two different transmission frequencies, and wideband measurements from 0.8 to 2.7 GHz were conducted in two rooms of an industrial environment. The theoretical results from the path-loss and rms delay spread prediction algorithm show good match with the measurement results. |
