Abstract
This paper presents a comparative analysis of the propagation models Hata Extended, SUI with a frequency correction factor, and Ericsson 9999 in mobile telephony systems operating in the 1900 MHz band (LTE). The study is carried out by measuring the electric field to establish a recommendation for an existing propagation model that fits the characteristics of the urban area of Ambato City. First, five base stations were located. Then, two base stations working in the band and technology mentioned above are chosen. Subsequently, four radial limits were drawn in the surroundings of the base stations, and four electric field measurement campaigns were carried out with the Narda SRM-3006 equipment for a total of 48 points for 6 minutes per point. In addition, the coordinates of the measurement points were determined using the Spectra Precision Mobile Mapper 50 equipment, obtaining the distances and heights of the terrain with great precision. With the data collected, the propagation losses are calculated to bring the theoretical electric field of each propagation model. Next, a comparison of the measured electric field values concerning each model's theoretical electric field values is performed to evaluate which model best fits the measurements. Also, a comparison of the RMSE is made. Finally, it is concluded that the SUI model with frequency correction factor is the best fit for the urban environment in Ambato.
