En este sentido, recientemente, dentro del sector de las telecomunicaciones se registró una demanda creciente en el uso y acceso a los servicios. Lo anterior genera la necesidad de que los operadores móviles expandan y aumenten la capacidad de sus redes de telecomunicaciones. Para lograrlo, es importante analizar las estrategias de aumento de capacidad y de cobertura de la infraestructura móvil de los principales operadores móviles. En este estudio, se realizó un análisis longitudinal de la densidad de los nodos por área geográfica a nivel municipal. También se analizaron los cuatro principales operadores móviles con red en México, a partir de datos colaborativos (crowdsourced data). Los datos se filtraron por tecnología LTE y se realizó una correspondencia entre los nodos y las bandas de frecuencia utilizadas por cada operador. Se analizaron las estrategias de aumento de capacidad de la red de los operadores y el porcentaje de uso de las bandas de frecuencia que cada operador tiene asignadas. Como resultado, se obtuvo que los principales operadores móviles con red en México han seguido una estrategia de cobertura similar. En los datos analizados no se encontró una correlación positiva entre la densidad de nodos y las características tecnológicas de las bandas de frecuencia. Se sugiere invertir en infraestructura nueva para el despliegue de nuevas tecnologías, y fomentar la cobertura móvil en zonas rurales. Por último, se recomienda facilitar a los operadores la arrendación de bandas en diversas frecuencias que permitan aprovechar las características tecnológicas de las mismas, mediante costos alineados al mercado internacional.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract It is known that access to mobile telecommunications, and through them to the Internet, can provide greater social well-being. Likewise, within the telecommunications sector there was a growing demand in the use and access to services. This generates the need for mobile operators to expand and increase the capacity of their telecommunications networks. In order to achieve this, it is important to analyze the strategies for increasing the capacity and coverage of the mobile infrastructure of the main mobile operators. A longitudinal analysis of the node density by geographic area was carried out at the municipal level. Likewise, the four main mobile operators with a network in Mexico were analyzed using crowdsourced data. Also, the data was filtered by LTE technology and a correspondence was made between the nodes and the frequency bands used by each operator. The operators' network capacity increase strategies and the percentage of use of the frequency bands assigned to each operator were analyzed. As a result, the main mobile network operators in Mexico have followed a similar coverage strategy. Likewise, in the analyzed data, a positive correlation was not found between node densification and the technological characteristics of the frequency bands. It is suggested to invest in new infrastructure for the deployment of new technologies, and to promote mobile coverage in rural areas. Finally, it is suggested to facilitate the leasing of bands on various frequencies that allow operators to take advantage of their technological characteristics; through costs that are aligned with the international market.]]></p></abstract>
