Beyond 5G: Reinventing Network Architecture With 6G

The roll-out of 5G has begun in many parts of the world and ought to get completed by the end of 2021. However, given the ever-increasing bandwidth demand and need for automation, the existing capacity of even the most technologically advanced network architecture is expected to run out by 2030. The aim of this paper is to have a peep into the future of wireless communication and its associated technologies. With a higher transmittal rate, improved spectrum efficiency, greater connection proportions, a greater spectrum coherence, and much shorter latency, 6G is expected to revolutionize the digital world. This paper presents the findings of a detailed study regarding the construction of 6G. The main focus of this detailed survey is on the 6G along the lines of mobile communication and the key technologies likely to be fielded on 6G enable networks. Towards the end, this paper also presents ongoing research initiatives being carried out by various research organizations.
