Its main requirements are to achieve high data transmission rates, massive user capacity, low energy consumption, high communication reliability and low latency. New antenna technologies have contributed to a notable improvement in mobile communication networks, providing them with of greater capacity, coverage, quality of service and mobility. These techniques have emerged according to existing needs, which have motivated competition between manufacturers to provide the best possible solution according to existing needs and marking an evolutionary character in the use of mobile antennas. That is why in this article a general description will be made of the systems that use large arrays of antennas in the base station, to transmit to multiple users in the same time-frequency resource and that have been proposed to solve these new demands.Ítem Diseño de un enlace de fibra óptica entre los municipios de Valledupar y Popayán.Pinzon Fernandez, Robert Isauro; Gomez Paredes, Juan CarlosThis project shows the design and simulation of a fiber optic link that joins the ends located between the cities from Valledupar and Popayán, choosing the best way to do it and through the simulation to discover which is the appropriate hardware for said solution, to be able to compensate for the needs of the network, this document will be divided into the following aspects: starting with the layout of the route between the municipalities from Valledupar and Popayán, continuing with the selection of both the wiring and the rest of the hardware necessary to establish said route in order to design and simulate the budget of energy and bandwidth so that it can be verified by simulation if the link meets the link quality.Ítem Mediciones comparativas de la experiencia de usuario en las redes móviles 4G y 5G actuales.Suárez Redondo, Camilo Andrés; Gómez Paredes, Juan CarlosThis document presents a comparison between measurements taken in fourth and fifth generation networks (LTE+ and NR-NSA, respectively).

This project proposes the development of a mobile application that acquires the patient's cardiac information from sensors and transmits it through a mobile device using the HL7 standard, to a database where the information will be available at all times and specialists can diagnose whether there are risks to the patient's health and thus avoid medical fatalities that may occur in the long or short term depending on the diagnosis made by the medical specialist. The information is acquired in the App, transmitted through the cellular mobile network and received in the server where it will be compared with a dataset that includes the patient's normal vital signs. The system will indicate if the data obtained are within the ideal ranges and the health professional can proceed with the corresponding treatment to avoid fatalities.Ítem Las amenazas de seguridad a las que se enfrenta IoT y las soluciones en desarrolloDavid Patiño, Dennis Rolando; Sánchez Galindo, Edgar Alexander; Gómez Paredes, Juan CarlosIoT is the main focus in the progress of the technology, its ambition to connect to Internet a huge variety of devices which we live together daily has created that its demand increase every day and it is no longer a small market niche, in fact, the growth of IoT is exponential and we can affirm that in the coming years we will have tens of millions of devices connected and controlled from Internet without any kind of human interaction. This includes the deployment of a big technological ecosystem where data management needs to be implemented through great computing and storage resources dedicated to data processing. However, the IoT growth has generated at the same time an increase in vulnerabilities that may affect devices and perhaps due to the desire of manufacturers to generate IoT solutions, the security information has not been the priority, and that information will be more sensitive and relevant day by day. The aim of this document is to highlight the main security problems that IoT faces, describing how these problems affect the end user and at the same time to study the possible solutions that have been developed to solve the problem.Ítem Puesta en servicio de una portadora nueva de LTE, en la banda de 850 MHz, para un operador de telefonía móvil en Bogotá.Prado López, Gustavo Hernán; Gómez Paredes, Juan CarlosThis article propose a methodology from the RF view, for the initial tunning of a LTE carrier, in 850 MHz band, for a mobile operator in Bogotá.

All these devices have different characteristics that make them have a better performance when using the mobile network, this depends entirely on the characteristics that each mobile terminal has, some have a higher performance than others due to the range either low medium high , this range depends entirely on the chipset with which the equipment is designed, some devices have the same chipset but some have more features enabled than others this is due to the issue of the final value of the equipment, which marks a higher value not lower for The end user. There are different tools that allow you to verify the performance of mobile devices, these can be proprietary of the manufacturer or also mobile applications that allow you to perform an analysis not as similar as a proprietary tool, but allow , you to make a network analysis and identify important values of mobile devices. These tools allow us to verify the different signal levels of the base stations, thus verify the behavior of the mobile terminal, and also see its behavior in the field and in in-building scenarios.Ítem Planeación y análisis de cobertura de una red móvil 3G y 4G en la Localidad de ChapineroOrozco Camargo, Camilo Andrés; Cortés Hernández, Cristian Camilo; Gómez Paredes, Juan CarlosThis document presents the network planning and coverage analysis in an urban environment, for the deployment of radio bases for 3G (UMTS) and 4G (LTE) technologies.
