This article validates a design methodology for a wireless telecommunications network to extend rural connectivity in Andean areas of Colombia in the post-conflict framework. The presented methodology allows the design of different types of networks according to geographic information of the urban-rural area of the municipality of Marulanda, located in the region of Caldas, Colombia. Internet connectivity will be delivered through a self-managing telecommunications technology known as WiBACK, which will support future 5G communication technology. Thus, the advantages and disadvantages of two network topologies are compared and a projection of the technological components for the implementation of the network is presented. The results of the research will design the roadmap and the comparative evaluation of the expansion scenarios of the Colombian broadband access network in post-conflict scenarios. En este artículo se valida una metodología de diseño de una red inalámbrica de telecomunicaciones para extender la conectividad rural en zonas andinas de Colombia en el marco del posconflicto. La metodología presentada permite el diseño de diferentes tipologías de red de acuerdo con información geográfica de la zona urbano-rural del municipio de Marulanda, localizado en la región de Caldas, Colombia. La conectividad a Internet se entregará a través de una tecnología de telecomunicaciones autogestionable conocida como WiBACK, que admitirá la tecnología futura de comunicación 5G. Así, se comparan las ventajas y desventajas de dos topologías de red y se presenta una proyección de los componentes tecnológicos para la implementación de la red. Los resultados de la investigación diseñarán la hoja de ruta y la evaluación comparativa de los escenarios de expansión de la red de acceso colombiana de banda ancha en escenarios de postconflicto.

We present deep near-infrared (K_s) images and surface photometry for 80 dwarf irregular galaxies (dIs) within ~5 Mpc of the Milky Way. The galaxy images were obtained at five different facilities between 2004 and 2006. The image reductions and surface photometry have been performed using methods specifically designed for isolating faint galaxies from the high and varying near-infrared sky level. Fifty-four of the 80 dIs have surface brightness profiles which could be fit to a hyperbolic-secant (sech) function, while the remaining profiles could be fit to the sum of a sech and a Gaussian function. From these fits, we have measured central surface brightnesses, scale lengths, and integrated magnitudes. This survey is part of a larger study of the connection between large-scale structure and the global properties of dIs, the hypothesized building-blocks of more massive galaxies.
