The explosion of mobile data traffic and emerging application scenarios (e.g., IoT, immersive multimedia/application, tactile internet) has propelled a drastic evolution from traditional 4G(long-term evolution(LTE)) networks. 5G) mobile system, is believed as no longer an evolution of 4G but a revolutionary industry driven and massively expanded service ecosystem that will enable us to connect the entire crowded world for more than 7 billion peopl world without any limitations and can constitute a "World Wide Wireless Web" (WWWW). The purpose of this paper is to give a well systematic overview of the 5G contributing in application areas for future communication networks. We analyze this transition, from 1G to 4G, with respect to the dynamics of RA technical systems settings, data rate and network technology. The essence of this paper is in depicting the enablers of 5G which include new network structures( hence reconfigurable multi technology cores and cognitive terminals)and game -changer physical layer technologies(hence Full- Duplex communication, Filter Bank Multi- Carrier crisis(FBMC), Non Orthogonal Multiple Access Noma).Sparce Code Multiple Access(Scma). We also comment on major enablers and supporting key technologies including SDR, CR,nanotech-nology, cloud computing to realize the 5G vision.. The study concludes that 5G is the preeminent technology for a digital society and resulted from naturally evolving technical specifications such as higher capacity, lower latency, faster.
