Optimización de un modelo de pérdidas de propagación en ambientes internos. Caso Campus UTPL

Abstract:

This research proposes the adjustment to a mathematical model indoor; applying to the propagation characteristics of the Building D and Building 7. The optimized mathematical model can pbkp_redict more accurately an attenuation of a signal passing through the various obstacles that are made up of the buildings. Through a measurement campaign in the mentioned infrastructure, and the use of specialized equipment in the transmission and reading of an electromagnetic signal (at 915 MHz), it was possible to obtain the signal levels that correspond to the loss in the interiors of the buildings and the respective analysis of the acquired data, besides it allowed the modification of the results to the theoretical model (Log-distance). In addition, this research includes a brief analysis of the attenuation produced in electromagnetic waves by humans, taking as a reference the density and body position.
