Currently, the fourth generation cellular communication provides a low latency that is insufficient. It is unable to cope up with the future requirements. The future is the enhanced version of today. Various aspects that are to be considered in the next generation of mobile communication are enormous unprocessed raw facts and figures, better data rates, increment in mobile devices etc. This technology is termed as 5G. This paper draws its attention on the advancements towards the improvement considered as the improved version of 4g i.e.5g. We discuss the comparative study that tells the evolution of previous generations in the case of cellular communication as well as the major limitations of 4g. All of these features will improve the performance scenario and will result in a better tomorrow.
