Combination of geometric and finite difference models for radio wave propagation in outdoor to indoor scenarios
G de La Roche, P Flipo, Z Lai… - Proceedings of the …, 2010 - ieeexplore.ieee.org
In this paper, a new model used to compute the outdoor to indoor signal strength emitted by
a base station is presented. This model is based on the combination of 2 existing models:
IRLA (Intelligent Ray Launching), a 3D geometric-like model especially optimized for
outdoor predictions, and MR-FDPF (Multi Resolution Frequency Domain ParFlow), a 2D
FDTD-like model initially implemented for indoor propagation. The combination of these
models implies the conversion of the ray launching signals on the border of the buildings …
