Abstract

This work aims to revolutionize the communication and data security infrastructure of small and medium-sized companies by implementing a digital radio link system, thereby establishing a secure network that can interconnect their telephone exchanges and wireless LAN networks The aim is to facilitate fluid and secure communication between the different locations, optimizing the management of critical information and improving the operational efficiency of the company. It incorporates advanced technologies for the establishment of the radio link, selecting the necessary equipment and software to guarantee maximum efficiency and security in data transmission. Evaluate aspects such as modulation type, Error Correction (FEC), and performance, among others, to set up an infrastructure that meets the needs of the business today and is scalable in the future. The use of 5 GHz band antennas and the selection of suitable network devices are crucial for achieving a reliable and high-performance link. To guarantee the integrity and confidentiality of the information transmitted, a secure network is designed by implementing encryption in the radio link, a double authentication system is developed for users who access the wireless LAN network, by creating a captive portal associated with the AAA Radius server, this infrastructure allows double authentication, which will guarantee secure and controlled access for customers and employees of any company.
