Abstract: The development of wireless technologies in recent years started an era of highly-effiencient information society. It is expected that the wireless technologies will become wider and deeper in the coming years. Understanding the greater importance of wireless communication in the future for both academies and industries around the world have initiated the study of the next generation, namely 5G, of wireless communication systems. The 5G technology ( fifth generation) also know as 2021 wireless network technology is the foremost phase of wireless communication standards ahead of current 4G/IMT standard. The coming 5G technology and Information & Communication technology (ICT) networks signify evolution of the globally connected digital society. The main contribution of this paper is definition of 5G i.e. Fifth Generation mobile network concept which is seen as user-centric concept instead of operator-centric as we have in 3G or service-centric concept as seen for 4G. In the proposed concept the mobile user is on the top of all.
