Estudio para la optimización del uso de la tecnología de la red móvil en la banda 700 MHz y 1700/2100 MHz para mejorar la cobertura en la ciudad de Milagro.

Abstract

The goal of this study is to develop and evaluate a proposal to improve the 4G mobile network in the Milagro canton, Guayas province, Ecuador, with the aim of increasing coverage levels, signal quality, and service capacity in urban and peri-urban areas. The initial assessment revealed that, while 4G coverage exists in the central part of the canton, some areas have received signal strength (RSRP) levels close to the minimum operating limit, as well as low signal-to-interference ratios (SINR), which directly impact throughput and user experience. Existing base stations are located between 2.7 km and 3.75 km from the urban center, resulting in estimated path losses of 110 to 130 dB, particularly at 1700 MHz. Following a technical and geographical study, a solution was proposed focusing on the tactical implementation of small cells. This solution incorporates the 700 MHz band to improve indoor coverage and penetration, along with the 1700/2100 MHz band to increase capacity in high-demand areas. Design verification was performed using simulations with Radio Mobile and QGIS software, integrating a Digital Elevation Model (DEM) to account for the topographic variations in the study area.
