The Next Generation in Communication Technology: Roadmap to 6G

Since the last quarter of 2022, studies on fifth-generation (5G) communication systems have been conducted under the name of beyond 5G studies. With the standardization of 5G communication systems, researchers have intensified their work on communication technologies beyond the 5G. The rapid advancements in communication technology have prompted 5G studies to focus on mapping out the roadmap for sixth-generation (6G) communication, which will be the next communication technology. This includes determining the vision and requirements for this new technology. This study investigates the developments in mobile communications from the first generation (1G) to the 5G, the main technologies and challenges in the fifth generation, and the expectations for 6G. It is expected that 6G will be operational by 2030 according to many researchers, countries, and companies.
