5th generation mobile networks
5G is the fifth generation of data networking hardware and data standards for mobile networks. The technology aims to deliver high-speed, low-latency data transmission and is viewed as an enabling technology for industries ranging from mobile devices to autonomous vehicle systems, augmented and virtual reality, edge computing, and the internet of things, among other application areas.
5G, as a term, is used to collectively refer to a constellation of mobile networking technologies and standards.
One of the first standards for 5G technologies was proposed by the International Telecommunication Union (ITU) in 2015. The ITU's requirements, known as the International Mobile Telecommunications-2020 (IMT-2020) standard, are slated to be finalized by 2020, but parts of the standard were finalized earlier. Its minimum requirements, finalized in 2017, specify:
The 3rd Generation Partnership Project (3GPP), a wireless communications standards body, proposed additions to IMT-2020. 3GPP regularly issues releases to its standards.
In April 2019, the organization published Release 15, a specification for the first phase of rolling out 5G NR, an implementation of the 5G standard. In Phase 1, 5G NR and LTE share common elements, such as both using orthogonal frequency division multiplexing (OFDM).But there are differences:
Release 15 also sets forth new nomenclature for device connection compatibility.
