6G: Opportunities and Challenges

Abstract

The Internet of Everything will soon become a reality that is to be acknowledged to 6G, or sixth generation, mobile network research and development efforts. With the help of 6G, a brand-new network would be created that connects almost everyone and everything, including machines, objects, and devices. Additionally, 6G will put an emphasis on quality of experience to deliver rich experiences with 6G technology. Notably, it is crucial to envision the problems and difficulties associated with 6G technologies. Researchers have been investigating numerous alternatives to attain the needed 6G characteristics and, hence, it is imperative to consider a variety of research challenges, from hardware to software capabilities. The major characteristics of 6G are THz-level data communication with a strong emphasis on short-range communications, network-inherent artificial intelligence, high network heterogeneity, and modified radio topology. From possibility to certainty, the main problems of 6G mobile communication technologies are 100% coverage, terahertz communication, optimal spectrum utilization, flexibility, redundancy and self-healing capability, and low-carbon transformation. © 2024 selection and editorial matter, Dr. Abraham George and G.
