5G as Enabler Technology for Smart City Use Cases

The smart city relies on smart management systems to protect the environment and improve the quality of life of citizens. This paper presents some related use cases and lists their various benefits. In addition, given the implementation of the current systems, specific requirements are presented as challenges to improve the actual delivery. To achieve this goal, this paper examines the role and potential of adding 5G New Radio (5G NR) technologies to smart city implementations. 5G NR is a new radio interface fully developed from the most basic level to support a wide variety of deployments and services. Therefore, an overview of 5G technology is provided here, along with a roadmap for the various releases to describe the 5G evolution path. Next, a discussion is conducted on the key services and features of 5G that are capable of supporting the improvement required in smart city development.
