A Survey on Enabling Technologies and Recent Advancements in 6G Communication

The growth of IoT and data-driven applications has caused network evolution with a demand for high internet speeds capable of handling data-intensive operations and high-performance computing in real-time. Despite massive strides in the past decade to achieve low-latency ultra-reliable network connections, by 2030, 5G technology will be unable to keep pace with emerging applications like unmanned autonomous vehicles, brain-computer interactive devices, extended reality (XR), ubiquitous AI, Internet of Everything and global network coverage. Subsequently, there will arise a need to transcend from 5G to 6G. 6G is being touted as the next giant leap forward to support ultra-fast intelligent networks resulting in speculations about the various use cases which will adopt 6G. We discuss the enabling technologies and recent advancements in the development of 6G. We talk about the most advanced and promising technologies that will revolutionise 6G communication. Furthermore, we give an objective analysis of these technologies and possible hindrances in their adoption.
