This paper proposes a hybrid modeling approach for prediction of the room-to-room radio propagation channel. The model combines ray tracing with propagation graph. The propagation graph vertices are obtained at each room by ray tracing with the assumption that the receive antenna (or transmit antenna) virtually locates on the surface of the separating wall between two rooms. Rays transmitting from one room to the other through the separating wall are deterministically calculated by Snell’s law of refraction. The proposed approach is validated by being applied to the real-world scenario and being compared with the measured data. The results show that the proposed modeling works with the simplest parameter settings, i.e. assuming no propagation from room containing receive antenna to room containing transmit antenna, ray tracing applied separately in each room only involves mechanism of line-of-sight and first order specular reflection.
