Item Rede Smart Grid: tecnologias de comunicação(2023-02-03) Prada, Jadson Augusto Simões; Cordeiro, Celso Souza; http://lattes.cnpq.br/4969144304480235; Cordeiro, Celso Souza; http://lattes.cnpq.br/4969144304480235; Souza, José Geraldo de Pontes; http://lattes.cnpq.br/3583358046117558; Ribeiro, Ewerton Andrey Godinho; http://lattes.cnpq.br/0187470129136467Among several discoveries and progress already achieved by science, electricity was one of the most impressive, and today, its presence is a decisive factor for the industrial, economic and social advancement of any region. In this sense, the concept of Smart Grid is highlighted as an intelligent network that can improve the efficiency of the system in general, considering the importance of energy management. However, for Smart Grids to be effectively reliable, it is necessary to integrate different types of equipment, communication technologies and data processing. And as a delimitation of this study, the communication networks that make up the Smart Grids are highlighted, as a topic of great importance in telecommunications systems. In this sense, the objective of this study is: To present the communication technologies that cover the Smart Grid network sector. To this end, a literature review was carried out based on publications in the area of Telecommunications, Energy and Technology, in libraries of higher education institutions and virtual libraries such as the Scientific Electronic Library Online - SciELO. It was verified that the communication system is the key element of the Smart Grid infrastructure, since all initiatives in Smart Electric Grids pass through a communication infrastructure. Therefore, an intelligent electrical system switches the entire supply of energy through the distribution network, managing the need for energy through a communication system. The technologies studied in this study were: Wi-Fi, SigFox, LoraWAN, ZigBee, WiSUN and GPRS, which are technologies that operate from data collection to the calculation of monitored electrical quantities. Thus, the intelligence of the network resides in the ability of the devices to communicate, exchanging information that makes it possible to build a safer and more efficient network, based on a broad telecommunications support.Item Redes wi-fi mesh: uma revisão de literatura(2023-03-02) Araújo, Raman Pimentel; Cordeiro, Celso Souza; http://lattes.cnpq.br/4969144304480235; Cordeiro, Celso Souza; http://lattes.cnpq.br/4969144304480235; Souza, José Geraldo de Pontes; http://lattes.cnpq.br/3583358046117558; Ribeiro, Ewerton Andrey Godinho; http://lattes.cnpq.br/0187470129136467Mesh Wi-Fi networking has been increasingly used as an efficient solution to coverage and performance issues in traditional Wi-Fi networks. With the growing demand for wireless connectivity in business and residential environments, Wi-Fi Mesh technology presents itself as an innovative solution to expand network coverage and improve the user experience. This course completion work aims to present a literature review on Wi-Fi mesh networks. For this, a literature review on Wi-Fi mesh networks was carried out in databases and academic publications, theses, dissertations and book chapters. In conclusion, Wi-Fi Mesh networking technology is an innovative and efficient solution to deal with coverage and performance issues in traditional Wi-Fi networks. With the ability to expand network coverage without compromising connection speed and stability, Wi-Fi Mesh networks are especially useful for environments with many connected devices and multiple access points. Additionally, setting up and managing a Wi-Fi Mesh network is relatively simple and intuitive, making this technology an affordable option for both home and business users. Therefore, Wi-Fi Mesh networking technology is a valuable and promising solution to improve connectivity and user experience in challenging Wi-Fi environments.Item A tecnologia lora no campo das telecomunicações, seus benefícios, inovações e características(2023-03-02) Medeiros, André Luiz Gomes de; Cordeiro, Celso Souza; http://lattes.cnpq.br/4969144304480235; Cordeiro, Celso Souza; http://lattes.cnpq.br/4969144304480235; Souza, José Geraldo de Pontes; http://lattes.cnpq.br/3583358046117558; Ribeiro, Ewerton Andrey Godinho; http://lattes.cnpq.br/0187470129136467With the increasing number of devices connected to the network, more and more the Internet of Things comes into focus. There are applications that demand high or low transmission rate, large or small coverage, or the need for little maintenance, for difficult access places, for example. There is a range of widespread technologies that can cover these demands, and this study highlighted LoRa technology in the field of telecommunications. In this way, the general objective of this monograph is: To present the performance of LoRa technology in the field of telecommunications, detailing its characteristics, benefits and innovations in the area. To this end, a clear and concise literature review on the subject was carried out, based on findings in the literature. It was possible to demonstrate that LoRa devices revolutionized the internet of things, enabling data communication over a long range, using very little energy. When connected to a non-cellular LoRaWAN network, LoRa devices accommodate a wide range of IoT applications, transmitting packets of important information. LoRaWAN networks bridge the technology gap for cellular and Wi-Fi-based networks that command high bandwidth or high power, or have limited range or inability to penetrate deep indoor environments. It was verified that the LoRa technology allows the development of several projects in the sector in which the amount of data to be transmitted by the sensors at the final edges of the structure is not very large. Thus, in episodes where videos, heavy images and other information need to be transmitted to the Application Server, perhaps LoRa is not yet a solution. However, in situations where more succinct information (texts and measurements, among other data) is sent, LoRa networks can be implemented with good performance, as highlighted in this study in the case of intelligent management of the water network, connectivity in the field, detection of natural disasters and environmental monitoring as well as location of assets.
