A Review of 6G: Towards The Future

Abstract

The first wireless communication signal was transmitted across the Atlantic by Marconi in the early 1900s. The world has been revolutionized by mobile communication since the 1980s. The internet has transformed all aspects of people's lives. As a result, communication and sharing of information have greatly improved. As 5G opens up endless possibilities, technology companies begin to wonder what 6G will bring. A 6G network will provide more than just communication in a new generation of mobile devices communications. An era of true intelligence in everything will begin when the physical, biological, and cyber worlds are connected by neurons. It will continue to evolve as connected people and things develop connected intelligence. Ultimately, it will bring intelligence to every individual, home, and business. A holistic view of 6G is presented in this article, the study highlights the most promising lines of research in the recent literature that support this vision. A key contribution of the paper is the exploration of 6G communications' critical issues and key features, including: The vision and key features of the organization; the challenges and possible solutions; and the research activities. For a specific, concrete, and concise conclusion to be reached, these controversial topics were critically examined in relation to their various sub-domains of motivation. This article will help researchers learn more about a topic so they can continue investigating it.
