The ultimate purpose of the upcoming 5G wireless networking is to provide customers with fast network speeds, low latency, important efficiency rises in base station and big developments in anticipated quality of service (QoS) relative to 4G LTE networks. The use of broadband data has increased rapidly, in line to handle new technologies and correlation in form of cellphones, Internet of Things (IoT), autonomous vehicles. Next, the system's bandwidth needs to be increased extensively to meet the latest applications. This development will be achieved with the use of a state-of-the-art spectrum with greater levels of data. The fifth-generation network, in particular, explore to determine the flaws of preceding telecommunications technologies and to create a potential basic facilitator for future IoT apps. This paper examines 5G structure, followed by the use case studies and security issues correlated with the 5G, 5G as an energy-adequate network, different kind of productive antennas invented for 5G, along with their related communication technologies. Future impact and challenges of 5G are outlined and explained. The paper is finished with conclusion and recommendations for future with 5G.
