Summary:
With the accelerated development of smart terminals and the increasing trend of new applications, wireless information traffic has improved sharply, and the evolving cellular networks (even 5G) cannot fully compete with the rapidly emerging technical needs. A new wireless communication framework, the sixth generation (6G) framework, mainly assisted by artificial intelligence is expected to be implemented sometime in the range of 2027 and 2030. This project presents a critical analysis of the 6G wireless communication vision and structure of its network. A number of important technical challenges are also described, such as opening up the sub-terahertz spectrum for increased bandwidth requirement and the ability to use these bandwidths, pushing the limits of semiconductor technologies to operate within these bands, developing designs and transceiver architectures to realize peak high data rates and achieve sub-second network-level latencies to meet 6G Key Performance Indicators. In addition, possible solutions related to 6G are specified, as well as physical layer transmission procedures, network designs and security methods.
More specifically, the structure of the project is as follows: In chapter 1, a brief introduction is made on the importance of telecommunications, reaching 6G. Following, in chapter 2 a reference is made to the previous generations of communications from 1G to 5G Advanced, focusing mainly on the latter, as it is also the current latest technology (together with 3G, 4G) in use. In chapter 3 is discussed the vision of the 6G architecture that could support it, as well as technical issues that may arise in areas such as radio access technologies, security, network resources, network heterogeneity, and tactile communications. In chapter 4 is discussed in more detail challenges encountered in 6G, referring to the requirements it will have to meet. Finally, in chapter 5, a summary is made and thoughts and conclusions for the future, determined by the evolution of 6G.
