Estudio de factibilidad de una red de área local inalámbrica aplicando la metodología top-down a una institución educación media.

Abstract

New technologies have the ability to connect one or more devices to the Internet. These are the most powerful, versatile and ubiquitous tools the world has ever known. ICT innovation is a variable and dynamic process at a global level. Educational institutions today have implemented technologies in their teaching methods to improve the quality of education. The management of network technologies has enabled various strategic areas such as health and education to optimize their resources. Among the most notable technologies of technological development in the last decade is wireless technology. This technology provides a connection to a data network from an intelligent device from any point in a certain geographical area, offering faster and more optimal communication, reducing installation costs and maintenance expenses. A network structure must be stable, reliable, robust and allow scalability by adapting to the traffic it will have. The network must adapt to the teaching processes and administrative operations in an agile way in the educational institution. Wireless networks are part of communication, society always seeks to be connected anywhere in the world through the use of wireless devices such as smartphones, laptops, smart watches, desktops, etc. These devices make communication faster and more optimal, since the absence of cables reduces installation costs. The wireless local area network is basically a system that transmits, transfers and communicates data, it does not require computers to be connected by structured cabling, since all network traffic is carried out through radio waves. Currently, the use of web sites has gained notoriety at the educational level, allowing the optimization of student records, the management of grades, as well as providing alternative methods, tools and platforms for teaching and research. The present degree project focused on developing a web site to evaluate if the implementation of a wireless local network is feasible, based on the TOP DOWN methodology using its six phases: 1. requirements analysis, 2. logical design, 3. physical design, 4. testing, 5. network implementation and 6. network monitoring; the evaluation was done through questions divided by phases governed on a Likert scale, this site has as its main page the last evaluations made reflected in a statistical graph with its respective table. In order to answer the evaluation, a previous analysis of the needs, requirements and services of the educational institution was carried out. This system was developed using the JavaScript language with its NodeJS framework for the server, the EJS template engine and PostgresSQL database; it has an MVC structure (model-view-controller, and a client-server network architecture (the user sends a request to the server, the server receives it, if necessary sends it to the database, receives the data and sends it back to the client to show it to the user. Once the web application was implemented, the SEO analysis and evaluation was carried out using web tools that provided data such as loading speed, response speed, code validation, responsive design, performance and security. This site was hosted in Heroku hosting providing other users the facility to know if their study is feasible or not.
