Evaluation of LTE Mobile Signal Propagation Models and Vegetation Attenuation in the Livestock Department at ESPOCH

Abstract

Introduction: Propagation models predict the power, or information, loss between a transmitting antenna (Tx) and a receiving antenna (Rx). The receive power data in a specific area can be measured empirically, so that comparisons can be made, and models can be found that best fit the actual measured data. Objective: To compare the Okumura-Hata, Ericsson 9999 and SUI propagation models with empirically obtained reception power measurements in an LTE antenna, to know the best prediction model in the open areas of the Departament of Livestock Sciences of the Escuela Superior Politécnica de Chimborazo. Methodology: Quantitative, analytical, and rationalistic approach. Scientific field research; collecting empirical data. Results: The SUI model shows an exponential trend in the prediction of power loss, while the Okumura-Hata and Ericsson 9999 models do not show a particular trend, because they are conditioned according to the attenuation by vegetation present in the area. Conclusion: The Okumura-Hata urban model with vegetation attenuation is the most adequate to predict power losses in the open areas of the Departament of Livestock Sciences of ESPOCH.
