Análisis comparativo de modelos de propagación para 4G en el valle de Tumbaco

Abstract

The following project talks about the evolution of mobile communications 1G, 2G, 3G and 4G with their respective characteristics used for mobile communication, it also analyzes the current status of the operators Conecel, Otecel and CNT as these are responsible for coverage in Ecuador, it explains the concepts of fading both small and large scale, It focuses on multipath fading, which explains how the environment affects the transmission of signals. Three propagation models that can be used in suburban areas are analyzed in this project, the Okumura-Hata, Cost 231-Hata and Walfisch-Ikegami propagation models were used. Chapter 2 shows the current situation in the distribution of BR of each operator throughout the country and the study is focused on the busiest area of the Tumbaco valley, since with the increase in population, the demand for larger buildings has also grown, and the area is moving from a rural area to a suburban area, For the calculations, a code was created to facilitate the obtaining of losses and the balance of powers, with this the error is obtained and the best propagation model for the valley of Tumbaco and the operator that has the best coverage in the area can be compared and determined.
