What is the greatest invention

In telecommunications, 6G is the sixth-generation technology standard for cellular networks currently under development for wireless communications technologies supporting cellular data networks. It is the planned successor to 5G and will likely be significantly faster.[1] 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 (Airtel, Anritsu, Apple, Ericsson, Fly, Huawei, Jio, Keysight, LG, Nokia, NTT Docomo, Samsung, Vi, Xiaomi), research institutes (Technology Innovation Institute, the Interuniversity Microelectronics Centre) and countries (United States, countries in the European Union, Russia, China, India, Japan, South Korea, Singapore and United Arab Emirates) 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 (IoT). It is expected that mobile network operators will adopt flexible decentralized business models for 6G, with local spectrum licensing, spectrum sharing, infrastructure sharing, and intelligent automated management underpinned by mobile edge computing, artificial intelligence (AI), short-packet communication and blockchain technologies.
The Next G Alliance, released its report on 6G in February 2022, outlining the development roadmap of 6G.As of 2023, there is no universally-accepted government or non-government standard for what qualifies as 6G technology and it is still in the early stage of development, but expect to be deployed in 2028 as scheduled.
