Análisis del canal móvil a pequeña escala (short term) en el centro histórico de Quito mediante simulaciones 3D para futuras implementaciones de 5G new radio (NR).

Abstract

The objective of the Curriculum Integration work was the analysis of the small-scale mobile channel (Short Term) in the Historic Center of Quito, through 3D simulations for future implementations of 5G New Radio (NR). Several points within the Historic Center were determined using the Open Map Street software, and through the scientific method, the behavior of the channel studied was evaluated. 5G New Radio has a set of options that allowed us to understand the propagation operation of the latest generation mobile network. Various characterization tests were carried out around the Plaza Grande, where the Transmitter Antenna was located at 20m of height. Finally, we proceeded to calculate the Bandwidth and Coherence time, in order to see if the mobile system needs to be or not equalized. The software used, evidenced that it does not accomplish with all necessary parameters to carry out an adequate characterization study. On the other hand, the mobile channel showed that it was not flat in time and frequency, reason why it is determined that it is necessary to make some modifications and adjustments of parameters to be able to carry out the proper equalization. It is recommended to improve the platform used, in order to carry out comparative studies about the new global trend in communications, the 5G network.
