- Abstract
- 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 transmitted from one room to the other through the separating wall are deterministically calculated by Snell’s law of refraction. Predictions by the proposed model are compared with measurement data from an office-to-office scenario. The results show that the proposed modeling works with the simplest parameter settings, i.e. assuming no propagation from the room containing receive antenna to the room containing transmit antenna, ray tracing applied separately in each room only involves mechanism of line-of-sight and first order specular reflection.
