    This project proposes the design and implementation of a digital FM broadcasting system using software-defined radio (SDR) platforms, with the aim of strengthening practical training in the Telecommunications field. Because adopting SDR technology with digital systems is very costly and complex, a functional prototype is proposed that uses open-source hardware and tools, allowing its replication in low-resource educational environments. The project consists of integrating functional blocks that simulate the behavior of a digital transmitter, using platforms such as GNU Radio and USRP-type SDR devices. Furthermore, the prototype is validated through transmission and reception tests, evaluating technical parameters such as audio quality, spectrum, and link stability. As a result, a digital system was developed using DvSwitch, in which a Raspberry Pi was configured to function as a server, given its relatively low cost, to perform the necessary configurations. Additionally, FM audio communication was successfully established using GNU Radio and USRP, verifying the spectrum and link stability.

    The project seeks to increase the rate of tourists on San Cristobal Island by implementing a tourism digitization system. To achieve this, it is proposed to develop a digital platform that allows tourists to plan and organize their visit to the island in a more efficient and personalized way. The platform includes detailed information about the island's tourist attractions, as well as accommodation, transportation and activity options. In addition, geolocation technology is included to guide tourists during their visit and provide them with personalized recommendations based on their interests and preferences. The project also contemplates the training of local tourism actors so that they can use and promote the digital platform, which will contribute to greater dissemination and adoption of the system. The implementation of the tourism digitization system is expected to increase the number of tourists visiting San Cristobal Island, which would have a positive impact on the local economy and the development of the region's tourism sector

    Caring for older adults year after year represents large investments for their assistance due to the degenerative process that prevents them from leading a full life or performing simple daily tasks. The need to have people in charge of their care also implies applying technologies that help them assist in risk events. This project develops and implements a home automation system based on IoT for the Comprehensive Center for the Elderly (CIAM) of the city of Ambato, which under the guidelines of the staff together with the author's skills, manage to determine specific requirements for the center. The design and construction of IoT devices for the monitoring of variables related to their environment and the control of the facilities, is complemented by a server in the cloud whose resources are directed to provide communication through the MQTT protocol. Automatic control is also integrated into its configuration to provide adequate environmental conditions for older adults, in the face of temperature values not indicated for their daily lives. Through a user interface developed in Node Red, the staff has the technology that supports the assistance of older adults, as well as the Notifications that the system generates when recognizing changes in the measured variables. Speech recognition is added to the system for device control using Raspberry PI. Forming a system capable of providing communication between devices and generating automatic notifications through mobile messaging services.

    The present titling work deals with the development of an access control system through facial and voice recognition, for the authentication of people in a home. Currently, the levels of insecurity have increased and this has led to an increase in theft and damage to real estate due to the low level of security in a home. The device developed in this project is based on a bimodal access biometric, through machine learning and neural networks, a subfield of Artificial Intelligence. The system has two authentication methods: facial and voice, for which neural network models designed by the researcher were used with the stages of: database formation, image and audio processing, and neural network design. He implements two methods of facial and voice authentication to avoid identity theft, a camera is responsible for capturing the person's face and performing recognition through the neural network, if the user is registered, the microphone is activated to capture the key of access and process it through the neural network, to record the data a LAMP server is used where the system information and user notifications are stored through the Telegram application. This project is aimed at controlling the access of people to a home, avoiding the use of traditional authentication methods.

    En el presente proyecto de investigación, se realizó el prototipo de un sistema de alarma comunitaria para el mercado “San Juan” de la ciudad Santiago de Píllaro, un centro que no cuenta con un sistema de seguridad y que a través de la tecnología, permite a la comunidad estar en alerta ante situaciones de vandalismo, brindándoles una forma de medidas de protección humana. El diseño del prototipo se ejecutó en una tarjeta Raspberry Pi 3B+, la cual se desempeña como el centro de procesamiento de todo el sistema, en base a dos modos de funcionamiento, de acuerdo a los horarios de apertura del mercado. Se hizo uso de la mensajería instantánea Telegram y WhatsApp, para el envío de alertas y alarmas tanto auditivas como visuales hacia los diferentes terminales de usuarios y unidades policiales. Para la alarma auditiva se utilizó un puerto GPIO de la Raspberry Pi y una cámara IP para el monitoreo y activación de alarmas en función a la detección de movimiento; todo esto se desarrolló a través del lenguaje de programación Python, en donde se crearon objetos, clases y funciones para ejecutar tanto las alarmas como el sistema de video vigilancia para un control remoto, por medio de una página web. La interconexión entre los dispositivos fue mediante la comunicación inalámbrica wifi que proporcionó el router. Otro servicio desarrollado fue la telefonía IP, en donde se usó Asterisk como centralita para la comunicación entre usuarios, todo ello en base a la configuración de extensiones e instalación del software softphone zoiper en los teléfonos móviles. Adicionalmente, se elaboró el diseño de la red wifi y del sistema de video vigilancia IP, utilizando equipos óptimos para el funcionamiento, en caso llegase a ser implementado. ABSTRACT In the present research project, the prototype of a community alarm system for the "San Juan" market of the city of Santiago of Píllaro was carried out, a center that does not have a security system and that through technology, It allows the community to be on alert for vandalism situations, providing them with a form of human protection measures. The prototype design was executed on a Raspberry Pi 3B + card, which is carried out as the processing center for the entire system, based on two modes of operation according to the opening hours of the market. Telegram and WhatsApp instant messaging was used to send both auditory and visual alerts and alarms to the different user terminals and police units. For the auditory alarm, a GPIO port of the Raspberry Pi and an IP camera were used for monitoring and activation of alarms based on motion detection; All this is executed based on the Python programming language, where objects, classes and functions are created to execute alarms such as the video surveillance system for a remote control, through a web page. The interconnection between the devices was powered by the wireless Wi-Fi communication provided by the router. Another service developed is IP telephony, where Asterisk is used as a switchboard for communication between users, all based on the configuration of extensions and installation of the zoiper softphone software on mobile phones. In addition, the design of the Wi-Fi network and the IP video surveillance system was developed, using optical equipment for operation, in case you get implemented.
