Comparison of 4G and 5G cellular network architecture and proposing of 6G, a new era of AI

In this 21 st Century, the deployment of wireless technology has created a spur amongst technologists about the future progression of wireless communication. It has not only transformed the way of communication but also paved a way for many multi-functional devices and technology. The essence of modern culture is the digital economy, which is also the base for a wireless system of connections. There was a time when wireless networks evolved, from 0G towards 4G along with their architectures and new features. The correlation is contrasting between 4G and 5G with their architectures, coverage, speed quality of service, bandwidth, and latency rates. But later the 5G system architecture conceptualized a full-bodied network, which introduced an architecture that worked intensively while the petulant analysis and consultations are stimulated to bring an advanced evolvement in the wireless community, hence 5G was slowly and gradually deployed all over the world. Meanwhile, the idea of 6G is being looked into and the researchers and engineers are working on its architecture and development, which will make it significantly different from the preceding generations some of which have made a mark and some that have not. This paper presents a complete understanding of variations between 4G and 5G wireless network architectures, the comparisons, and the evolvement through all these years. The analytical and factual results help in advancing an evolved 6G architecture and the change, enhancement, and transformation it will bring in the future of Wireless Cellular Networks.
