5G
Fifth-generation mobile telecommunications standard
Overview
5G refers to the fifth and current generation of cellular network technology and the successor to 4G. In common commercial use, the term refers primarily to mobile networks based on the 3rd Generation Partnership Project (3GPP) 5G system and its New Radio (NR) air interface, which were first specified in 3GPP Release 15. 5G was developed to meet the International Telecommunication Union's IMT-2020 framework for fifth-generation mobile systems. Large-scale commercial deployments began in 2019, including South Korea's national 5G rollout. 5G networks may be deployed in non-standalone mode, using existing LTE core-network infrastructure, or in standalone mode with a dedicated 5G Core.

Key concepts
How 5G connects to the ideas, people and events around it.
A cellular network or mobile network is a telecommunications network where the link to and from end nodes is wireless and the network is distributed over land areas called cells, each served by at least one fixed-location transceiver.
4G refers to the fourth generation of cellular network technology, introduced in the late 2000s and early 2010s.
The 3rd Generation Partnership Project (3GPP) is an umbrella term for a number of standards organizations which develop protocols for mobile telecommunications. Its best known work is the development and maintenance of:GSM and related 2G, 2.5G, and 2.
5G NR is a radio access technology (RAT) developed by the 3rd Generation Partnership Project (3GPP) for the 5G mobile network. It was designed to be the global standard for the air interface of 5G networks.
The International Telecommunication Union (ITU) is a specialized agency of the United Nations responsible for many matters related to information and communication technologies.
International Mobile Telecommunications-2020 are the requirements issued by the ITU Radiocommunication Sector (ITU-R) of the International Telecommunication Union (ITU) in 2015 for 5G networks, devices and services.
In telecommunications, Long Term Evolution (LTE) is a standard for wireless broadband communication for cellular mobile devices and data terminals. It is considered to be a "transitional" 4G technology, and is therefore also referred to as 3.
A cell site, cell phone tower, cell base tower, or cellular base station is a cellular-enabled mobile device site where antennas and electronic communications equipment are placed on a raised structure to create a cell, or adjacent cells, in a cellular network.
