Abstract
his paper presents a Building Information Mod- elling (BIM) data conversion algorithm for radio wave prop- agation studies in indoor and outdoor environments. The tool presented here allows to extract the geometrical and physical information of BIM models present in IFC2x3 files. The first conversion step is done using the IFCOpenSHell library through a Python interface and the second one is done using MatLab. Following MatLab results extraction, studies of propagation will proceed. The extracted information allows ray tracing simulations and/or radiowave propagation studies through a real- scale simulation scenarios, spending less computational time. The results presented refer to a small wooden house for a frequency of 3.6 GHz, for 5G, using a directional transmitter antenna and an omnidirectional receiving antenna. It is possible to check the result for the direct component and first, second and third order reflections.
