Future applications such as intelligent vehicles, the Internet of Things and holographic telepresence are already highlighting the limits of existing fifth-generation (5G) mobile networks. These limitations relate to data throughput, latency, reliability, availability, processing, connection density and global coverage, whether terrestrial, submarine or space-based. To remedy this, research institutes have begun to look beyond IMT2020, and as a result, 6G should provide effective solutions to 5G shortcomings. 6G will offer high quality of service and energy efficiency to meet the demands of future applications that are unimaginable to most people. In this article, we present the future applications and services promised by 6G.
