Análisis comparativo de modelos de propagación para 4g en el norte de Quito

Abstract

This technical project addresses the evolution of telecommunications, with a focus on mobile communications and the evolution of cell phone network technology. This progress has led to the emergence of new devices and services. Each generation of mobile network (1G, 2G, 3G, 3G+, 4G, etc.) is associated with an innovative technology (GSM, GPRS, EDGE, UMTS). With each technological evolution, mobile networks improve in performance, allowing faster data transmission. It also analyzes the status of the three operators that are responsible for coverage in the country which are OTECEL, CONECEL and CNT, which provide mobile data service to users, this with the analysis of the different propagation models that for this project were used three, OKUMURA HATA, COST 231, COST 231 WALFISH, COST 231 WALFISH and COST 231 WALFISH, COST 231 WALFISH IKEGAMI, in these models the parameters are explained and also the different types of variables that are for each model, as well as concepts such as fades that focus on multipath fades emphasizing the various causes that may affect the transmission of different signals are also addressed.
