Simulación y corrección de zonas de sombra para estaciones de televisión digital terrestre en la ciudad de Cuenca, provincia del Azuay, Ecuador.

Abstract

Nowadays, Digital Terrestrial Television (TDT) in Ecuador is in a transition phase in which it is anticipated that the first stage of migration will be fulfilled by mid- 2018 and the migration of all the open analogue television systems to digital format will be completed by 2020. Currently, in Cuenca there are TDT systems that are performing tests for their operations. TDT systems in comparison to conventional analogue systems show significant differences, being the coverage one of the most important to be considered. This is why it was necessary to carry out a coverage analysis for TDT stations in Cuenca. Based on this premise, this research sought to analyze the areas of shadows generated by TDT stations in Cuenca and appropriate solutions were proposed for the elimination of them through: field measurements of electrical intensity on site, the use of the specialized software for coverage ICS Telecom. This software implements ITU R-1812 propagation model, radiant systems modeling- Antios and an analysis of co-channel interference for SFN networks. At the end of this research, technical parameters were presented to be considered in order to obtain adequate coverage in Cuenca. Furthermore, future recommendations were made to be considered in the planning of these digital systems.
