Modelos de propagación para edificaciones coloniales en la ciudad de Loja

Abstract

This degree work proposes an electromagnetic wave propagation model adapted to the characteristics of indoor environments for buildings of Ecuadorian colonial architecture, which is obtained by applying two adaptation mechanisms: the method of least squares and the determination of an attenuation constant. The data needed to adapt the model is obtained in a measurement campaign carried out in a series of colonial buildings, where, with the use of transmission and reception equipment, the power losses of an electromagnetic signal at the frequency of 2,437 GHz could be measured as it propagates through specific obstacles within these structures. Also, a comparative analysis of the Log-distance, ITU, Motley-Keenan and One Slope theoretical models is made. After the respective mathematical analysis, this data allows the adaptation of the Motley-Keenan model. Finally, the validation of the proposed propagation model is carried out and it is concluded that the formulated model presents an average error of less than 3 dB and therefore is apt to be applied in this type of buildings.
