Evolution of wireless communication networks from 5G to 6G future perspective

Industry 4.0 relies heavily on artificial-intelligence(AI) and cloud-computing(CC), both of which have been greatly aided by the 5th-generation mobile-network (5G). The arrival of 5G, however, is seen as a watershed moment that will radically alter the current global trends in wireless communication practices and the lives of the masses. 5G envisions a future where the digital and physical worlds merge. The 6th-generation (6G) wireless communication network will likely unite terrestrial, aerial, and maritime communications into a single, unified system that is both more stable and faster, and can accommodate a far larger number of devices with ultra-low latency needs. This research hopes to foresee a scenario in which 6G supersedes 5G as the dominant standard for wireless communication in the years to come. Several advances have been made, but the utopian period of instantaneous global communication, instantaneous global computation, and no latency has not yet arrived. This essay investigates the most significant obstacles and difficulties that the transition from 5G to 6G may encounter on the way to realizing these loftier goals. The vital goal of "technology for humanity" is to improve service to the world's most disadvantaged people, and this article lays out a plan for 6G that includes the enabling technology infrastructures, obstacles, and research directions that will get us there.
