Abstract
En la actualidad existe una creciente demanda de Servicios de datos a través de red celular en entornos rurales y remotos. La disponibilidad de esta conectividad IP de banda ancha por red celular se considera fundamental como factor impulsor de crecimiento socio-económico para estas regiones y escenarios. Tres tecnologías se presentan como elementos clave para el desarrollo de este tipo de servicios. En primer lugar la tecnología de small cells que proporciona un nodo de acceso radio a usuarios del servicio celular, flexible, de bajo coste y rápido despliegue, en segundo lugar la tecnología LTE, que aporta prestaciones y flexibilidad suficientes para proporcionar capacidades de banda ancha sobre la red celular y en tercer lugar la tecnología satélite que a través de los nuevos satélites de mayor capacidad y adaptados al servicio de datos, permite servir de enlace de interconexión de backhaul para conectar la red de acceso de small cells con la red troncal de los operadores móviles y prestar conectividad celular LTE en regiones rurales y remotas carentes de servicios IP. La convergencia de estas tres tecnologías está dando paso a un nuevo mercado potencial para la industria satélite en el cual se tienen puestas muchas expectativas y que permitirá el despliegue de forma intensiva de soluciones de conectividad LTE basadas en small cells con backhaul satélite en escenarios muy diversos: comunidades rurales, industria remota, medios de transporte aéreo y marítimo, entorno militar, etc.
En este proyecto se analizan de forma pormenorizada todos los aspectos relevantes que permiten entender las claves del desarrollo de la conexión de backhaul satélite para la prestación de servicios celulares LTE a través de small cells en entornos rurales y remotos.
Today there is a growing demand for IP connectivity via cellular network in rural and remote environments. The availability of this IP connectivity broadband cellular network is considered essential as a driver for socio-economic growth in these regions and scenarios. Three technologies are presented as key to the development of this type of service elements. First small cells technology that provides a radio access node to cellular users, flexible, low cost and rapid deployment, second LTE technology, which provides benefits and flexible enough to provide broadband capabilities on the cellular network and thirdly satellite technology through new higher-capacity satellites and adapted to the data service, can serve as backhaul interconnection link to connect the access network of small cells to the backbone of the mobile operators and provide LTE cellular connectivity in underserved rural and remote regions of IP services. The convergence of these three technologies is giving way to a new potential market for the satellite industry in which they have placed many expectations and will allow the deployment of intensively LTE connectivity solutions based on satellite backhaul and small cells in many different scenarios: rural communities, remote industry, planes and ships, military environment, etc. In this project we analyze in detail all aspects relevant for understanding the keys to the development of satellite backhaul connection to provide cellular services through LTE small cells in rural and remote environments.
