Results show that when large scenarios are analyzed, adaptive meshing is necessary to avoid algorithm divergence, leading to accurate results when comparing with real measurements. In addition, simulation results of an indoor large and complex scenario in terms of received power and power delay profile are presented, showing significant influence of multipath propagation in indoor radio channel behavior. The use of the adaptive meshing for the analysis of large and complex scenarios can aid in the adequate deployment of wireless communication systems for large, complex indoor scenarios.
