“…Indoor path-loss predictions using RT are also usually satisfactory [8][9][10], at least if penetration is accounted for. This mechanism is particularly important in the absence of LOS or when the terminals are positioned in different rooms.…”

This article investigates the prediction accuracy of an advanced deterministic propagation model in terms of channel depolarization and frequency selectivity for indoor wireless propagation. In addition to specular reflection and diffraction, the developed ray tracing tool considers penetration through dielectric blocks and/or diffuse scattering mechanisms. The sensitivity and prediction accuracy analysis is based on two measurement campaigns carried out in a warehouse and an office building. It is shown that the implementation of diffuse scattering into RT significantly increases the accuracy of the cross-polar discrimination prediction, whereas the delay-spread prediction is only marginally improved.

This paper investigates the prediction capabilities of a Ray-Tracing tool with advanced features, i.e., diffuse scattering and penetration, in terms of the angular spreads and spectra of the directional propagation channel. In particular, it highlights the angular behavior of dense multipaths, which may represent a nonnegligible part of the received power, by comparing Ray-Tracing simulations with experimental data (office and laboratory environments). Results show that a Ray-Tracing approach including diffuse scattering is able to reproduce the dense multipath angular spreads, with errors around 4 to 20 degrees, and that scattering from ceiling is significant to predict the elevation spread. The assumption that diffuse scattering is clustered and strongly related to the most significant specular components is also successfully validated.

Connectivity and security of tactical mobile ad hoc networks (MANETs) can be enhanced significantly by explicit consideration of radio propagation as this not only allows determination of route feasibility and minimization of radio frequency power, but also avoids detectability of emanations. Tactical MANETs (and increasingly general MANETs) typically have geolocation and terrain information available, however as they are likely to be deployed in urban, broken, or indoor environments, simple Free Space or Two-Ray Ground models are not adequate. Although highly accurate radio propagation models exist, they require considerable computational resources and are hence unsuitable for incorporation into real-time protocols, particularly on resource-constrained platforms such as MANET nodes. We therefore propose a simplified, scalable ray-optical radio frequency propagation model that incorporates a Two-Ray Ground model and takes reflections and deflections on terrain features into account. Although our proposed model does not incorporate a comprehensive model of all physical effects, we argue that the approximation provided by our model is sufficient and suitable for the purposes of enhancing network performance and accuracy in the frequency range currently used by wireless networks. The model was incorporated in the NS-2 simulator and validated both using simulation and experimentally
