The evolution of telecommunications technologies has brought significant transformations to contemporary society, particularly with the advent of fifth-generation mobile networks, known as 5G. This technology promises higher connection speeds, lower latency, and the ability to connect a significantly larger number of devices simultaneously, enabling advancements in solutions such as the Internet of Things (IoT), smart cities, industrial automation, and real-time connectivity. However, the deployment of 5G in regions with specific geographic and socioeconomic characteristics, such as the city of Manaus-AM, presents technical, logistical, and social challenges that warrant scientific investigation. This study aims to analyze the main factors influencing the implementation of the 5G mobile network in Manaus, considering its current technological infrastructure, the logistical obstacles posed by the Amazon region, the socioeconomic impact of the technology, and the prospects for the development of Industry 4.0 within the Manaus Industrial Hub (PIM). The research adopts a case study methodology with a qualitative and quantitative approach, based on bibliographic review, document analysis, and secondary data collection from sources such as ANATEL, IBGE, ITU, and telecommunications operator reports. The results indicate that, despite recent progress in terms of coverage and spectrum availability, there are still limitations related to fiber optic infrastructure, antenna density, and unequal access in peripheral and riverside areas. Furthermore, the integration of 5G into the local industrial sector still requires substantial investments in modernization and technical training. The study concludes that achieving the full benefits of 5G in Manaus requires coordinated efforts between public policies, operator strategies, and digital inclusion initiatives. This research contributes to the understanding of regional challenges in the deployment of 5G in Brazil and provides insights for more equitable and sustainable technological development strategies.

According to Fisch (2002), the Amazon Region has an average rainfall of approximately 2300 mm, although it has regions where the annual total reaches 3500 mm. In their work, Figueroa and Nobre (1990) used 226 rainfall stations to identify the spatial and temporal distribution of rainfall in the Amazon region. This survey identified in detail the period of the year where rainfall occurs most frequently in the region, while the period of highest rainfall was identified between November and March. The city of Manaus, is located in the central part of the Amazon, Region that have high precipitation rates over 600 mm. This work was developed with the objective of analyzing the effects of these atmospheric precipitations on the signal propagation of the LTE 4G technology in the city, to identify areas of low coverage, since these failures are due to rapid rains, heavy rains or long term rainfall. Natural phenomena that frequently occur in the rainy season of the Amazon Region. Signal Prediction software installed on a notebook was used to collect this data received by the network access equipment, a modem enabled for web access and other services, and a Frequency Scanner was also used to collect the Gross Signal, the electromagnetic wave itself emitted by the Base Radio Stations (ERB) installed by the city of Manaus in several strategic points. Subsequently, a comparison was made of the measurements made in the environment with enough trees and few buildings with opposite climatic conditions, intense rains and intense sun. The chosen location of the first comparative analysis is located in the neighborhood of Santa Etelvina, chosen for analysis of aerial images of the city of Manaus with the Free Software Google EARTH. The second location chosen for the comparative analysis was the neighborhood of Cachoerinha, where there are quite old buildings and not much wooded and following the same criteria, opposite climatic conditions, intense rains and intense sun. With the comparative, we can verify attenuation that occurred in the rainy season and improve the coverage in those periods that frequently occur in the city.
Projeto de revitalização da infraestrutura da rede do Hospital e Pronto socorro Dr. João Lúcio Pereira Machado
(2024-12-04) Cruz, Elizandra Ferreira dos Santos; Santos, Alyson de Jesus dos; http://lattes.cnpq.br/5998752909180697; Souza, Daniel Fonseca de; http://lattes.cnpq.br/4043793492782488; Fontinelle, Carlos Gomes; http://lattes.cnpq.br/8988006492142629
This work proposes the modernization of the logical infrastructure of the Dr. João Lúcio Pereira Machado Hospital and Emergency Room, implementing a ring network topology with the additional possibility of aggregating future link redundancy. The initiative aims to increase the reliability, availability and resilience of the hospital's IT systems, ensuring the continuity of healthcare services in the event of communication failures. The choice of ring topology is motivated by its ability to provide multiple paths for data traffic, reducing points of failure and enabling agile recovery. Traffic redundancy is crucial to maintain the uninterrupted flow of information, even with failures in specific segments of the network. The project involves analyzing the existing infrastructure, identifying specific needs, planning and implementing the new network architecture, considering technical, operational and security aspects. Floor plans and network topology models will be used to illustrate the project. The expected result is a robust, secure and highly available communication network, which supports the hospital's daily operations and future technological demands, improving the quality of services provided to the population and optimizing hospital care and management.
