Análisis de la calidad del servicio en redes de comunicaciones de datos 4G y propuesta para mejorarla

Abstract

This monograph describes the situation of the quality of service QoS in Bogota Colombia, which places it outside the top 100 countries in 2024 in 4G speed. Initially a compilation of results of studies on 4G networks in the world is made, going through the history of the technology from 1G, 2G, 3G, to 4G LTE, the information found for Bogota is presented with dates and mobile operators to authorized (claro, tigo, movistar, wom) by the CRC, its distribution in spectrum for the area, with the Resolutions: Resolution CRC 4000 of 2012, Resolution CRC 5050 of 2016, Resolution CRC 5400 of 2018, Resolution CRC 6000 of 2022, coverage maps are shown, average tables of indicators for each operator with upload speed, latency, jitter, packet loss. Once given this context, the measurement system is chosen with the SIM7600G module and the G-net Track lite tool; these will be compared in 8 points of the city described with GPS coordinates, The SIM7600G system receives a python 3 script that will take the measurements, G-net Track will be used to contrast that they are within a close range; The SIM7600G system receives a python 3 script that will take measurements, G-net Track will be used to verify that they are within a close range; a driving test (vehicle displacement) is performed to verify the stability of the network in the face of displacement and finally with the average of samples with SIM7600G of the 8 zones of the city will be used to compare the data with those registered with the CRC page by the operators, conclusions are drawn from these results, From these results, conclusions and recommendations are drawn and a solution proposal is submitted based on the initial research, proposing the implementation of Self-Organizing Networks (SON) state collaboration in a pilot plan in selected areas of Bogota for adjustments and refinement to be made by specialized engineers to improve the quality of service QoS in Bogota or other areas of the country.
