Ítem Using 3D game engines and GPU for ray launching based channel modeling in indoor(Institute of Electrical and Electronics Engineers Inc., 2014-08-23) Giménez, Jordi JoanThis paper investigates the use of a full 3D ray-launching system based on Game Engine and GPU for the prediction of channel parameters in indoor. We explore the behavior of the materials and the possible influence of objects external to the room where measurements were performed. We explore the modeling of indoor channel for Digital TV frequencies and analyze the behavior of material on such low frequencies and how the frequencies affect the constitutive parameters of materials in the scenario. Because of the environment used for experimentation, the number of rays is very high and the number of interactions is higher than usual. We show results of the ray tracing model compared with measurements of delay spread at 594MHz in a meeting roomÍtem Using game engines and graphic technologies for ray-tracing in future wireless(Institute of Electrical and Electronics Engineers Inc., 2014-04-11) Guevara, DinaelWe present here a discussion about the use of 3D ray-tracing (RT) techniques based on game engines and graphic technologies to derive the multipath channel. Our approach harnesses the power of video game development engines to provide the urban 3D model and 3D RT for exploration and analysis of multipath channel for a wide frequency range in different complex outdoor scenarios. The advantage of this approach is that it efficiently utilizes the potential and capabilities in the graphical processing units (GPUs) and provide high performance in computing time with accurate results. We demonstrate the usefulness of this approach using our 3D RT in different applications. We show simulation results and compare them with measurements, obtaining a good fit. © 2014 European Association on Antennas and Propagation.Ítem Work in progress - Serious 3D game for mobile networks planning(IEEE, 2010-10-30) Madriñán, PatriciaSerious games is an emerging technology growing in importance for specialized training, taking advantage of 3D games and game engines in order to improve the realistic experience of users. The concept of a serious game combines the concept of computer games used for recreational purposes with specific goals like training specialized personnel and is part of the concept of blended learning. The idea of a serious game for radio planning requires some level of abstraction and a combination between visual designers and engineers in order to maintain accurate concepts about radio and a good "feeling" from the gamer or user side. In this paper we expose the development of a serious game for Telecommunications planning training, which uses open source tools and real data from Digital Terrain Maps. We combine some innovative ideas about propagation models, 3D modeling of digital terrain, game engines and a traditional radio planning too
