## 1 Introduction  
Use and access of information and communication technologies (ITCs) are identified worldwide as fundamental factors for the economic and social development of each country, especially for underdeveloped or emerging countries where inequalities are present in everyday life. For this reason, in 2015, the United Nations (UN), through the Sustainable Development Goals (SDG), presented the objectives that would govern the countries strategic development until the year 2030. SDG goal nine (9), entitled \"Build resilient infrastructure, promote inclusive and sustainable industrialization and foster innovation\", in its target 9.C states, \"Significantly increase access to information and communication technology and strive to provide universal and affordable access to the Internet in least developed countries by 2020\" [1]. International Telecommunications Union (ITU) statistics on the behavior of global ICT development indicators from 2001 until 2019 show the progress in subscribers per 100 inhabitants for mobile telephony, Internet use, fixed telephony, mobile broadband, and fixed broadband [2]. Except for fixed telephony subscriptions, the indicators have increased since the \"Millennium Declaration\" in 2000 (see Figure 1) when the objectives prior to the SDGs were presented. Despite the efforts made by different governments, there are notable deficiencies in terms of fixed broadband connections and individuals who use the Internet worldwide. Against this backdrop, different technological institutions, companies, and organizations have advanced regarding the development of technologies that can facilitate ICT access economically sustainable initiatives that allow connecting rural areas where around 60% of the population without connectivity resides [3]. Such is the case of Google Loon balloons, Facebook Aquila drone, low-orbit satellites, Fraunhofer Fit Institute technology WiBACK, or efforts to implement free cellular network technologies allowing broader coverage of mobile operators to rural areas at a more accelerated rhythm. Reduce the digital divide, understood as \"the separation that exists between people (communities, states, countries...) that use information and communication technologies (ICT) as a routine part of their daily life and those that do not have access to same and that, even if they have them do not know how to use them\" [4]; as part of the social and economic revolution necessary to promote the most vulnerable population development and thus, provide opportunities regarding education, economics, research, and health services. For example, in Montes de Maria subregion, Colombia, there is a Plan of Action for Regional Transformation (PATR--Plan de Accion para la Transformacion Regional) which raises as objective to improve the transport, energy, connectivity, irrigation, and drainage infrastructures for agricultural production that allows regional integration and access to goods [5]. Some difficulties that must be overcome from government institutions to carry out social intervention projects are associated with both up-to-date information on territorial realities such as demographic density, territorial location, and installed capabilities, as well as the precariousness of transport infrastructure, decisively to improve accessibility and increase productivity, or network infrastructure to improve digital connectivity. The absence of updated information and the lack of adequate infrastructure make it difficult to access public information as an essential condition for government institutions' trust generation, while distrusting the institutional makes it difficult for social interaction and becomes an obstacle to sustainable and human development [6]. This work is part of Colombia Cientifica Program entitled \"Reconstruccion del Tejido Social en Zonas de Posconflicto\", and one of its objectives is to integrate connectivity services to rural development models through the backhaul network design and installation to improve rural connectivity areas of Sucre department, Colombia.
