    Cidades inteligentes com infraestrutura de comunicação 5G
    (Centro Universitário do Estado do Pará, 2018-05-07) Teixeira, Cindy Emanueli da Silva; Silva, Luã Barros da; Cypriano, Tiago Morales; Santos, Michelle Bitar Lelis dos; http://lattes.cnpq.br/1208797288539861; Brito, Itamar Jorge Vilhena de; http://lattes.cnpq.br/5143837732124006; Sousa, Marcos Paulo Alves de; http://lattes.cnpq.br/6713232502495902
    In a smart city, intelligent cars could communicate to smartphones, as well as traffic lights and other cars to anticipate traffic conditions and even to avoid collisions, it means that a large proportion of communication will take place between machines, not humans. In addition, with global mobile data traffic expected to grow eight times until the end of 2023, there is a need for more efficient technology, higher data rates and better spectrum utilization. New applications such as 4K / 8K video streaming, virtual reality and emerging industrial use cases will require greater bandwidth, increased capacity, security and lower latency, and this will only be possible with the use of 5G networks. There are already several initiatives of isolated intelligent cities in operation that offer a clue about what is to come with 5G technology and this work aims to demonstrate the operation of these intelligent cities using 5G resources and the requirements for its operation, as well as a theoretical proposal for the implementation of intelligent traffic lights in the city of Belém, which will bring a better operation of the city traffic and a new design in the city performance, bringing new opportunities for people, businesses, health and transportation.

    A tecnologia SDN em redes móveis 5G
    (Centro Universitário do Estado do Pará, 2018-06-15) Ferreira, Flávio da Costa; Carvalho, Pedro Lucas Araújo de; Santos, Michelle Bitar Lelis dos; http://lattes.cnpq.br/1208797288539861; Araújo, Marcos Venicios Conceição de; http://lattes.cnpq.br/2560715841923487; Souza, Paulo Tadeu Resque de; http://lattes.cnpq.br/1696401468737572
    The new technologies that will boost the development of smart cities, autonomous cars and the internet of things will significantly increase the data rates of networks. A diverse range of new devices will emerge and with them the need to attend a series of requirements, in addition to the demands for extremely low latency and extremely high throughput. 5G joins this scenario as a solution to this new era that requires a high number of connection at the same time. In this first moment, the new network is being implemented using the core infrastructure of the existing 4G network, however, a new core is being standardized and will use SDN and NFV technologies, seeking to bring simplicity and flexibility, transforming the current model into a totally new paradigm with great benefits. This work aims to understand, through a technical study, the application of SDN in this new architecture developed for 5G, detailing its operation and highlighting advantages and disadvantages, emphasizing that it will bring dynamism for the network services and it is presented as a key technology for achieving several challenges required in this new generation of mobile networks.
