5G: A digital society

Breakthroughs in wireless innovations are changing the economic and societal growth in entirely new way. Mobile communication has become everyday commodity due to rapid increase in demand of user to access the real-time world. Humans are continuously attached to their device, and the need is forcing the evolution beyond limit. LTE(Long Term Evolution) in 3GPP has reached a mature state, whereas LTE - Advanced is already been implemented with the data rates getting close to Gbps. The concept of 4G has been intensively discussed already, with its architecture following the same old-school pattern. This paper will define the concept of 5G (Fifth Generation) mobile network, which will be user-centric instead of operator-centric. We will discuss on productive results of 5G after separating indoor and outdoor communications. The article will boast on the potential cellular architecture, and discourse other promising technologies for 5G wireless communication system, such as MIMO communication, enhanced VoIP, Green technology, Visible Light Communication and few Coding Techniques. 5G technology aims to reduce the challenges like spectrum efficiency, latency and high-speed vehicular communication.
