Estudo, análise e otimização de uma rede WAN empresarial interconectada por radioenlaces P2P e P2MP

Abstract

Microwave links continue to be an important solution in the field of telecommunications. Despite the emergence of competing technologies such as optical fiber and 5G, radio links are still the most suitable choice for serving remote regions or areas with geographical limitations, especially in cases where the client requires fast communication with its branches located kilometers away. This work aims to present the study and optimization of the telecommunications infrastructure of a company that has all its branches integrated into a single high-performance, low-latency WAN network. In addition to the study, a brief overview of the large-scale IP PABX voice system used by the company is provided, as well as the speed and reliability of data exchange between employees and the server, located kilometers away. The study is developed based on various stages, from the planning of the microwave link to its implementation and testing, including some important network-level configurations such as protocols, routing, and port redirection, as well as the analysis of data exchange performance between branch networks. The use of consolidated databases, such as Google Elevation API and Google Earth, is crucial to ensure the accuracy of the project, as well as the assistance of the Pathloss software for system sizing and loss calculations, along with the mathematical tool Matlab for simulations and graph generation. An optimized systemic methodology is applied, tailoring the project to meet the technical and economic objectives of the company, avoiding over-sizing and using margins in certain parameters as needed for precision. For internet connectivity, the company has a contract for optical fiber service with the local provider, and the Starlink satellite network service will be added as a backup link.
