Low power wide area network (LPWAN) technology has expanded and is essential in the development of applications for the internet of things (IoT). The Sigfox LPWAN network is characterized by its long-range coverage, low cost and power consumption. In this article, a set of 5174 values is analyzed, containing 1606 null RSSI data, obtained with the Sipy module and MicroPython, which provide a coverage map of several points with a resolution of 200 meters deployed in Quito–Ecuador. It is evaluated the type of distribution to which the set of network measurements is adjusted and an optimal 900 MHz propagation model in suburban environments is determined from the measurements obtained from the known base station. As a result, the lost values of RSSI were predicted using the inverse normal distribution method in the original values, observing that they conform to a logistic distribution. The data from the base station were subjected to a data augmentation algorithm designed in MATLAB, determining that the stanford university interim (SUI) model reduces the precision error in the trend of the curve by not presenting changes greater than 5 dB, achieving a precision of 97% with respect to the fit of the curve of the data.

This paper presents an analysis of propagation models using power intensity levels measured with the Cell Info Lite application at the Department of Computer Science and Electronics of ESPOCH University, using Movistar’s LTE technology. Using Google Earth software, the base radio was precisely located based on the coordinates obtained. Concentric circles were then drawn, covering 145 points outside the Department of Computer Science and Electronics, covering an area of 36400 m^2. At each point, three measurement campaigns were performed on different days, but with similar schedules. The objective was to compare propagation models and observe variations in losses within the proposed scenario. The findings indicate that the Erceg model aligns closely with the measured values obtained from the Cell Info Lite application. Therefore, this model is considered the most suitable for this particular scenario. These results have significant implications for the deployment and optimization of LTE technology, specifically in scenarios similar to the Department of Computer Science and Electronics at ESPOCH University. The selection of a suitable propagation model, such as the Erceg model, can greatly improve network planning, coverage and performance for Movistar users.

“…En la evaluación de rendimiento de los modelos de propagación se tuvieron en cuenta: la pérdida por trayectoria media, el error de predicción y el error de predicción porcentual; como se hizo en otras investigaciones [8], [21]. El error medio y el error porcentual se obtuvieron por medio de (19) y (20).…”

“…De estas categorías, los empíricos son una opción práctica y eficiente de calcular la pérdida de potencia en un canal inalámbrico a partir de mediciones de campo. Sin embargo, su principal desventaja es la falta de precisión que se presentan al ser usados en entornos distintos de aquellos en los cuales fueron concebidos [8].…”

Tres modelos de propagación empíricos fueron comparados: Cost 231 Hata, Walfisch Ikegami (WI) e Interino de la Universidad de Stanford (SUI); para determinar su efectividad en un entorno urbano. Se hicieron mediciones en la banda de los 1900 MHz en un sector de la ciudad de Barranquilla, Colombia; y la evaluación se hizo mediante comparación de valores de error de predicción y relativo de cada modelo con respecto a las mediciones. Los resultados muestran que el modelo WI presentó el menor error relativo en comparación con el Cost 231 Hata y SUI tipo B. Los niveles altos de error indican que los modelos comparados no representan adecuadamente las mediciones en el escenario considerado.
