In telecommunications, 6G is the sixth generation mobile system standard currently under development for wireless communications technologies supporting cellular data networks. It is the planned successor to 5G and will likely be significantly faster.
Like its predecessors, 6G networks will probably be broadband cellular networks, in which the service area is divided into small geographical areas called cells. Several companies, research institutes and countries have shown interest in 6G networks. 6G networks are expected to be even more diverse than their predecessors and are likely to support applications beyond current mobile use scenarios, such as ubiquitous instant communications, pervasive intelligence and the Internet of Things
6G will dramatically increase capacity and lower latency for wireless-data transmission, 6G promises to enable applications on new orders of magnitude or which are qualitatively new.
6G’s performance parameters are still being defined, and its enabling technologies are still in relatively early stages of research and development (R&D).
China Telecom issued a white paper setting out its vision for 6G
