Validación de un modelo de propagación empírico, considerando variables ambientales, para las áreas rurales de la cuenca baja del río Guayas en la frecuencia de 5 GHz.

Abstract

The proper design and planning of the local area wireless networks or WLANs, depends mainly on the accuracy of the simulation tools, with which the feasibility studies are carried out and it is in this context that the importance of having reliable propagation models is appreciated and adapted for the different environments of interest where a telecommunications system will be implemented, since by having a successful propagation model, predictions of the signal levels will be achieved with a greater degree of confidence. In the case of outdoor environments, the number of variables such as environmental, type of land, vegetation, etc., generate the need for more specific propagation models such as the "Lower Guayas River Basin" considered in the present study due to its economic and productive interest for Ecuador. The present study validates the efficacy of an empirical propagation model prepared from 310,552 measurements collected between November 2018 and July 2019 for 36 subscriber clients on the 5GHz frequency, also considering the effect that the presence of rain has on the signal levels received with the use of a weather station. The results obtained allow us to determine that the elaborated empirical propagation model has a higher level of effectiveness, for the environment and frequency considered, than several of the bestknown and widely used models do.
