Resumen
Introduction. It is known that in any transmission system what propagates are electromagnetic waves which are transmitted and received and knowing the trend in which it varies with distance is one of the fundamental requirements for a reliable and efficient cellular transmission system. Objectives: To conduct a comparative study of five propagation models in different scenarios in the northern area of the city of Riobamba; to determine which of the five models included in the study is the most applicable in each case. Methodology: To make a comparative diagram by means of graphs showing the trend of each of the propagation models with respect to the measurements obtained by means of the software. Results: The SUI propagation model is the one that was adapted to the scenarios proposed because its calculations to determine path losses include more specific data within a suburban area. Conclusions: After the respective investigations and the results obtained, it was determined that from a considerable distance between the base station and the mobile receiver, the reception power decreases.
