Due to the exclusory, growth in the number of connected devices- predicted 50 billion connected devices in 2020 (Gary Davis, 2020) that demand internet access, an upgraded network is required. The fifth generation is the newest mobile network replacing the 4G technology. Deployed from 2020 in many countries, 5G will provide revolutionary innovations in mobile technologies that will reach various high-level goals to the costumers as well as Companies .To benefit from 5G network services, the whole word is growing up rapidly towards the 5G by developing a clear perspective to include the main challenges, opportunities and key technology components. In this paper, an attempt has been made to provide an overview about the evolution of mobile generations from 1G to 5G by comparing the challenges and features that have evolved from each generation, describe the various scenario of 5G deployment, and discuss the best choice Implementation of 5G NR.
