Technologies Assisting the Paradigm Shift from 5G to 6G

Abstract

AbstractArtificial Intelligence (A.I.), Blockchain, and Internet of Thing (IoT)-based applications require a massive resource, enormously high data rates, and increased throughput of 1 Tbps. To accomplish these requirements, existing 5G network may not be proficient. 5G will likely not have the ability to fully meet the needs of new applications based on self-driven vehicles, drone technologies, virtual reality (V.R.), augmented reality (A.R.), mixed reality (M.R.), and extended reality (E.R.). 6G networks will be the data superhighway and make the intelligent cyber-physical world fully connected. The 6G technologies are surprisingly helpful for integrating people, devices, vehicles, sensors, information, cloud resources, and robot specialists. 6G network enables great data rate, ultra-low latency, high bandwidth speeds, high quality of services, energy efficiency, and intelligent spectrum utilization. This chapter focuses on the evolution of 1G-6G and technological advancement that enabled a paradigm shift from 5G to 6G. Performance metrics of 6G is compared with 5G, and key features of 6G are also highlighted in the proposed chapter. Terahertz communication, MIMO, and fast full-inclusion access will bring about the densification of the 6G network. Further, the chapter also introduces 6G applications with emerging technologies.Keywords6G5GNetwork architectureTerahertz (THz) communicationBlockchainSecurityIoE
