Abstract: Everybody loves speed and speedy internet, so there is no surprise that every major telecom in the world is working to make it even faster. Following the rise of 4G cellular mobile technology; academics, representative mobile operators, academic institutions have begun to explore the technological progress to 5 G communication networks due to some of the key demands of higher data rates, increased capacity, reduced latency and improved Quality of Service. Recently, various research works or projects involving major mobile equipment manufacturers, scholars and foreign mobile network providers have been launched to create the 5G mobile communication technology base. Nevertheless, it was not clear that 5G mobile services were made available for use, their architecture and their performance. We represent in this paper a thorough overview of the next-generation mobile technology which is 5G. We focus on 5G network architecture, 5G radio spectrum, ultra-dense radio access networks (UDRAN), mobile traffic offloading, cognitive radio(CR), software-defined radio (SDR), software-defined networking (SDN), mixed infrastructure and societal impact of 5G networks.
