Indoor coverage : Out2InSight
Conventional wisdom in the RF world says that the building material and frequency are the only relevant factors when predicting building penetration losses. This would appear to be true when predicting with classical models or ray-tracing engines that do not calculate the 3D angle of incidence. However, now that this capability is available in WaveSight, accurate building penetration losses can be calculated leading to accurate indoor predictions.
Once the signal has penetrated the outside wall, the indoor loss calculation is a dB per meter loss model.
Since indoor building databases, details about wall structure and material might not be available, ray tracing is not needed. Furthermore, changes to the indoor environment can be highly variable, even during the course of a day, such as closing of doors/blinds or moving indoor plants. Therefore, a straightforward indoor loss model is often sensible.
The WaveSight outdoor-to-indoor model is based on the model developed within the Cost-231 project.The resulting signal level attenuation gives a very accurate prediction of the coverage inside buildings on multiple floors.
