Health, culture, study and work services are all available in the palm of your hand without leaving your home. Being connected is not synonymous with leisure, many responsibilities involve computerized systems and the internet is the means to reach them. Loaded with this thought, this work brings the technical vision behind the implementation of a Mesh network system in a home environment, a technology that increases the Wi-Fi coverage capacity and simplifies the way to connect to the internal network. The work aims to identify the main problems that befall the wireless transmission medium and, through a case study with an applied research nature, introduce changes that directly improve the user experience in terms of stability, mobility and performance. The development indicated that the bad positioning of the access points was the biggest responsible for the instability in the connection, where the implementation of new network devices that guaranteed the performance and brought gains of 611.11%, when comparing the lowest speeds registered. The 2.4GHz coverage achieved strong signal incidence across the scene and the addition of the 5GHz frequency introduced a new level in terms of speed. These records give account of even attractive specifications, but quite achievable by simpler networks, the real gain of this work is to provide freedom to the user, while the devices connected to the network can be moved around the environment without any limitation or loss of connectivity.
Análise e implementação da técnica de invasão Man-in-the-middle em redes sem fio IEEE 802.11 com a elaboração do relatório incidente

As technology advances, people become more susceptible to network intrusions, and the Manin-the-Middle invasion becomes extremely dangerous because of its ease of implementation. The purpose of this monograph is to create an incident response document, based on an implementation of a Man-in-the-middle attack carried out on the Centro Universitário do Estado do Pará - CESUPA network.
Proposta de dimensionamento de enlace Wireless PTMP

In several locations in the State of Pará the most viable, technically and economically accessible way to the internet is via radio link. Internet providers using copper cable or fiber optic links are not yet interested in small municipalities or peripheral neighborhoods in the metropolitan region of Belém. This work aims to propose a methodology for the dimensioning of a PTMP (Point-to-type) link -Multipoint) optimized to serve customers in geographically different positions within a 2km radius and with different internet plans (5Mbps, 10Mbps, 15Mbps and 20Mbps). For this, we analyze the main factors that can interfere in the propagation of the radio signal, we study methods to optimize the parameter adjustments of the equipment and we dimension a proposal for a PTMP link in Ananindeua - PA. In the end, we hope to optimize the quality of the end customer's connection.
