A Decision Support Framework to Conceptualize the Impact of 5G on Smart City Ecosystem

5G, fifth-generation technology, is driving digital transformation in the smart city ecosystem by allowing omnipresence of the network and a huge number of interconnections. There are abundant discrete studies on technology use cases related to smart cities; however, the impact of 5G technology on smart city has not been significantly covered as of yet. Therefore, the aim of the paper is to understand the impact of 5G technology on the Smart City ecosystem and how it leads to smart decision making. A decision support framework has been used to structure the process of deriving insights for better decision making in smart cities. The study aims to explore the following aspects; a) Applications of 5G in Smart city ecosystem b) A Decision support framework for better decision making in smart cities. A narrative literature review approach has been used in which literature related to the emerging 5G technology has been analysed with respect to smart cities. Academic documents published in peer-reviewed scientific journals, reports, and articles have been used for research. The paper aims to provide insights to academicians on the use of 5G applications in a smart city ecosystem, and practitioners on developing solutions for Smart Cities using 5G technology for effective decision making.
