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.

The urbanization growth and world capitals industrialization were expressive in the last decades, although pollution problems, fuel and constant congestions threaten the efficiency of urban development. Electric vehicles are a promising option to contribute in the energy diversification and an alternative to polluting forms commonly used in urban and rural road infrastructure, despite the differences between the duration recharging and refueling times between the types of vehicles. The inteligente transportation systems represent the implementation of transport advanced technologies to sense and process road conditions to improve traffic fluidity and avoid accidents. In order to improve the efficiency of electric vehicle charging, the research proposes the integration of recharge infrastructure with intelligenttransportation systems as a way of assisting drivers and companies seeking to join the new ecological trend.
Projeto em internet das coisas aplicada a um cenário residencial visando a melhor implementação e experiência do usuário

The Internet of Things consists of a network of physical objects capable of gathering and transmitting data. Such technology is characterized by the large number of connections, devices and countless applications, all integrated to the Internet and working together, interconnecting all current and future services. In the realm where physical objects connect and create a transmission network, the scenario of Smart homes emerges that have often been conceptualized as a creative dream for communities of the future. For these services to meet the needs of users and become a reality, it is necessary to collect a large amount of data, needing to identify all network devices and integrate them into an intelligent system. It is at this point that this monograph comes into play, aiming to carry out a case study and develop an efficient and simplified home automation infrastructure focused on the use of the Internet of Things. The project transforms the room of a common house into an intelligent one, using few resources and making the integration of several physical objects to a network controlled by a virtual assistant that, through routines and voice commands, automates the environment.
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.
