El presente trabajo aborda el diseño de un sistema distribuido de captura y visualización de espectro para la banda ISM de 2.4 GHz, con la capacidad de capturar el SSID, el RSSI y el canal de frecuencia de una red Wi-Fi para generar reportes gráficos que permitan observar el funcionamiento de la red y aplicar mejoras en caso de ser necesario. En primer lugar, para el desarrollo de este proyecto se diseñaron cuatro nodos sensores capaces de recolectar las variables de interés sobre la red. Luego, se implementó un servidor con el lenguaje de programación Python que permitiera la recepción de la información y su posterior visualización. Finalmente, se realizaron diferentes pruebas con el sistema de cuales se encontró principalmente que es posible a partir de la información presentada por los nodos en la interfaz de usuario; determinar si el lugar donde se encuentra ubicado el router es el más indicado y si el nivel de interferencia en el canal donde se configuró la red afecta de forma significativa la tasa de transmisión de datos ; This paper is about the design of a distributed spectrum capture and display system for the 2.4 GHz ISM band, with the ability to capture the SSID, RSSI and frequency channel of a Wi-Fi network to generate graphic reports that allow to observe the operation of the network and apply improvements if necessary. In the first place, four sensor nodes capable of collecting the variables of interest on the network were designed for the development of this project. Then, a server was implemented with the Python programming language that allowed the reception of the information and its subsequent visualization. Finally, they carried out different tests with the system of which it was found mainly that it is possible from the information presented by the nodes in the user interface to determine if the place where the router is located is the most indicated and if the level of channel interference where the network was configured significantly affects the data transmission rate ; Proyecto de grado ...
