Ítem Applicability of Game Engine for Ray Tracing Techniques in a Complex Urban Environment(IEEE, 2010-09-10) Navarro Cadavid, AndresThis work presents results for a new method of ray tracing in urban environments using game engine and graphic processing unit (GPU). First advantage obtained with this method is the simplicity for 3D modeling from raster digital elevation model (DEM). Second advantage is the ability to precisely obtain ray parameters and the multiple paths interacting between transmitter and receiver in urban environment for high and low base station. A third advantage is the reduction in computing time by using the GPU capacity. In this paper, we show simulation results and compare them with measurements, obtaining a good fit. ©2010 IEEE.Ítem A 3D Game Tool for Mobile Networks Planning(IEEE, 2010-02-10) Madriñán, PatriciaIn this work, we show the concept of serious game applied to a 3D game for mobile planning. We combine the use of a traditional planning tool with a 3D game engine, representing propagation models as "avatars". The tool allows to execute an initial planning and also to "play" a game according to "missions" like perform a planning with a coverage objective.Ítem Prediction of Delay Spread Using Ray Tracing and Game Engine Based on Measurement(Institute of Electrical and Electronics Engineers Inc., 2015-05-11) Gomez, JorgeIn this paper, we show results of channel delay spread estimation using a 3D ray launching tool based on Game Engines and GPU, comparing simulation results with channel measurements of a MIMO system taken in Ilmenau. We show that the accuracy of the simulation is strongly affected by the ray angular separation in the first and second diffraction, obtaining a good fit between measurements and simulation.
