5G services are characterized by unprecedented need for high rate, everywhere availability, ultralow latency, and high reliability. The convergence of access and metro networks, which revolves around two key trends of infrastructure integration. With the advancement in the networking technologies the next generation network (NGN) architectures must be 5G-ready & must be capable to support the next generation of applications and services. The convergence in the networking dimension, designates the integration of heterogeneous infrastructure across different network segments to allow end-to-end control of networking resources; aiming towards the integration of different types of networks, mobile, fixed and data centers, to enable end-to-end resource management. This paper provides extensive information about 5G network its features, expectation and future of Wireless network (SDN/NFV, MEC & Network Slicing) and also studied about FMC & data center consolidation.
