An Android phone, showing that it is connected to a 5G network An Apple iPhone showing that it is connected to a 5G Network. In telecommunications, 5G is the fifth generation of cellular network technology, which mobile operators began deploying worldwide in 2019 as the successor to 4G. 5G is based on standards defined by the International Telecommunication Union under the IMT-2020 ...
It was designed to be the global standard for the air interface of 5G networks. [2] It is based on orthogonal frequency-division multiplexing (OFDM), as is the 4G (fourth generation) long-term evolution standard. The 3GPP specification 38 series [3] provides the technical details behind 5G NR, the successor of LTE.
The following parameters are the requirements for IMT-2020 5G candidate radio access technologies. [6] Note that these requirements are not intended to restrict the full range of capabilities or performance that candidate for IMT-2020 might achieve, nor are they intended to describe how the technologies might perform in actual deployments.
From the latest published version (Rel. 18) of the respective 3GPP technical standard (TS 38.101), [5] the following tables list the specified frequency bands and the channel bandwidths of the 5G NR standard. Note that the NR bands are defined with prefix of "n". When the NR band is overlapping with the 4G LTE band, they share the same band number.
3GPP has set an early revision, non-standalone release of 5G called New Radio (5G NR). [6] It will be deployed in two ways, Mobile and Fixed Wireless. The specification is subdivided into two frequency bands, FR1 (<6 GHz) and FR2 (mmWave) respectively. [7]
Cellular network standards and generation timeline. This is a comparison of standards of wireless networking technologies for devices such as mobile phones.A new generation of cellular standards has appeared approximately every tenth year since 1G systems were introduced in 1979 and the early to mid-1980s.
DECT-2020, also called NR+, is a radio standard by ETSI for the DECT bands worldwide. [1] [2] The standard was designed to meet a subset of the ITU IMT-2020 5G requirements that are applicable to IOT and Industrial internet of things. [3]
The 3GPP specification work is done in Technical Specification Groups (TSGs) and Working Groups (WGs). [23] There are three Technical Specifications Groups, each of which consists of multiple WGs: RAN (Radio Access Network): RAN specifies the UTRAN and the E-UTRAN. It is composed of six working groups.
