In Latin America, progress must be made in the generation of adequate infrastructure to continue growing in broadband services, especially through mobile technologies, which, like the world trend, far exceed broadband services over fixed networks. However, the fundamental thing from the infrastructure point of view is that, whatever the access or last-mile technology, physical integration is required through networks (backhauls, metropolitan networks, backbones and international carrier service networks). sufficiently robust, efficient in terms of information transport capacity, and safe, such as fiber optic systems, which become the great integrating medium, since by constituting New Generation Network technologies (NGN - Next Generation Network) will be able to support the convergence of multi-technologies, multi-services, and therefore, be the ideal foundation for the unbridled growth of content and use of applications. For the development of ICT infrastructure in developing countries, it is essential to have adequate government policies and, hopefully, state policies that promote ICT plans and actions aimed at the universalization of services, which if they can be executed jointly together with a harmonized regulatory environment, can facilitate and promote new investments in ICT, thus managing to boost economic growth and important advances, among others, in sectors such as health, education, justice, transportation and increase connectivity and penetration of band services high-speed broadband, to finally have a positive impact on GDP, employment and obviously reduce the digital divide in developing regions. In this work, statistics of mobile and fixed broadband services are presented worldwide, where it is possible to locate Latin America within the developing countries, making clear the dominance and growth of mobile over fixed services, but showing that this accelerated growth, without a doubt, requires all efforts to react, in terms of Convergent infrastructure and technologies, at the rate of the insatiable needs of connectivity, communication, information, mobility, data analysis, cloud computing, entertainment, among others, being this for obvious reasons, a much greater challenge for societies and / or or governments of developing and underdeveloped countries.Ítem Redes 5G como desarrollo de las redes NGN(2021-02-08) Chica Pedraza, Gustavo Alonso; https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0001394035; https://scholar.google.com/citations?hl=es&user=56zzi_0AAAAJ; https://scienti.minciencias.gov.co/gruplac/jsp/visualiza/visualizagr.jsp?nro=00000000001433; https://orcid.org/0000This document seeks to present a brief study of fifth generation networks, or 5G, as part of the future development of next generation networks.

Pay-as-you-go involves a high price per unit hour but does not require long-term commitment. The subscription-based pricing models are cheaper than pay-as-you-go in the long-term but normally require a long-term commitment and associated vendor lock-in. In this chapter, the currently employed pricing models in cloud computing are briefly described (Section 4). Advance Reservations (ARs), an efficient way to guarantee the availability of a given amount of resources for use at a specific time in the future, are studied (Section 4). Then, the concept of pay-as-you-book (Section 4), a novel manner of acquiring cloud resources in advance for future use based on ARs, is presented. Pay-as-you-book combines the main advantages presented in pay-as-you-go and subscription-based pricing models: no long-term commitment and low cost, respectively. At the end of this chapter, a case study comparing the impact of different resource allocation policies on the economies of a Virtual Cloud Provider (VCP) is developed (Section 4).Ítem Part I.

These data should be consulted to the white space software platform in Colombia, developed by the INVTEL group in 2018. As a result, two technical concepts will be issued, a capacity building strategy for CTeI - academic group-, a final report of research, and a thesis of the master of telecommunications and ICT regulation. In order to achieve this objective, it is necessary to develop software tools that allow the automation of the consultation process for each of the geographical points of the country according to the necessary resolution / granularity, establish the necessary data structure for the storage of said data so that They can be processed for later visualization in heat maps. This whole process requires the development of specific skills in Mongo DB, elasticsearch, python, linux and visualization of heat maps, selecting the best way to articulate these tools for the proposed objective. In addition, knowledge of national regulation, the calculation model, and the operation of the white space software platform in Colombia is necessary to adequately analyze the current regulation and make the pertinent recommendations.

In Colombia for some years, work has been done on how to reduce the digital gap and although by 2018 the country has 98.6% of the existing municipalities with high-speed transport networks to the headwaters, plans for Last mile network infrastructure in small municipal seats or rural areas are only just beginning and fixed internet penetrations are very low. Therefore, and in order to find solutions with a view to continuing to reduce the digital divide that exists in the country, this study proposes to analyze the feasibility of using Broadband Power Line technology in 100% subsidized housing projects located in areas remote and of low demographic density (defined zones thus on the part of the National Government).Ítem Aplicación de la teoría de toma de decisiones en ambientes complejos en el campo de las telecomunicaciones(2017) Chica Pedraza, Gustavo Alonso; http://scienti.colciencias.gov.co:8081/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0001394035; http://scienti.colciencias.gov.co:8085/gruplac/jsp/visualiza/visualizagr.jsp?nro=00000000001433Initial RecordÍtem Establecimiento de reglas de compresión encabezado para la interconexión de dispositivos IoT en redes LoRaWAN a IPv6 mediante la implementación SCHC de referencia desarrollada por IMT Atlantique - Caso: sistema de monitoreo ambiental en la USTA(2017-10) Zona Ortiz, Angela TatianaLPWAN networks have been shown as the solution for the deployment of solutions IoT with low power consumption for the node and good coverage. However, the interconnection of IoT devices in LPWAN networks with IP networks has become a problem. Therefore, from IMT Atlantique they are working with organizations of standardization in the family of SCHC protocols that seek the compression of IPv6 header so that this interconnection is possible, which is reflected in a draft. This draft must be validated through experimental studies in different networks and with different applications, so that it is verified that SCHC is the solution effective and efficient as possible to the interconnection problem. For which they will have to Define different header compression rules and validate in a experimental on real implementations. The present proposal seeks to establish the compression rules that are the most beneficial in the implementation of the SCHC protocol, in an implementation environment of an environmental monitoring system composed of two IoT nodes in the Santo Tomás University on a LoRaWAN network.

This separation is possible thanks to the introduction of controllers in the control plane and the forwarding devices of packages in the data plane. The controllers are responsible for the optimization of network operations, by means of the management of the operation of the devices of forwarding The presence of a single controller in an SDN not only represents a only point of failure, but it brings with it latency and scalability issues. A) Yes Well, the deployment of multiple drivers in an SDN is recommended, especially in large-scale networks or under heavy load conditions. While the multiplicity of drivers in SDN networks is a fact, the problem of their location is a subject that is currently under study by the scientific community. East problem does not have a single solution, nor model that characterizes it, since the location of the controllers in SDN networks is subject to optimization criteria (e.g. scalability, load balancing, resilience, communications delay between controllers), the network topology and the restrictions that it may impose on the controllers and the forwarding devices. To deal with this problem we have defined both exact and heuristic models. This proposal deals with the optimization of location of the controllers in WAN SDN networks. This problem will be addressed in collaboration with IMT Atlantique and will be articulated with students of the Master in Telecommunications and ICT Regulation, undergraduate in Engineering Telecommunications and the MAGNADATA seedbed.
