Indoor prediction of propagation using dominant path: Study and calibration

In this paper, we are interested in predicting signal level inside buildings. A new model is presented and described. The free space model and the two-ray model predict the received power as a deterministic function of distance. Recently, dominant path algorithm has introduced as an alternative thanks to its low computational time. It relies on the determination of the least attenuation path, the wave guiding effects and the loss interactions. In this paper, we extend the dominant path model to take into consideration the multi-floor case and the antenna pattern radiations. Our contribution consists in a specific method to solve these problems. Moreover, a method for the indoor dominant path calibration is introduced.
