IMT-2020
{{Short description|Official standards for 5G connectivity}}
International Mobile Telecommunications-2020 (IMT-2020 Standard) 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.{{Cite web|url=http://www.itu.int/net/pressoffice/press_releases/2015/27.aspx|title=ITU defines vision and roadmap for 5G mobile development|website=www.itu.int|access-date=2019-04-15|archive-date=2020-05-23|archive-url=https://web.archive.org/web/20200523144637/http://www.itu.int/net/pressoffice/press_releases/2015/27.aspx|url-status=dead}}
On February 1, 2021, the standard was published as Recommendation ITU-R M.2150-0 titled Detailed specifications of the radio interfaces of IMT-2020,{{Cite web|title=ITU towards "IMT for 2020 and beyond"|url=https://www.itu.int:443/en/ITU-R/study-groups/rsg5/rwp5d/imt-2020/Pages/default.aspx|access-date=2021-08-17|website=ITU|language=en-US}} but most of it was finalized years earlier.{{Cite web|title=What Is IMT-2020?|url=https://www.sdxcentral.com/5g/definitions/imt-2020/|website=SDxCentral}} For example the requirements for radio access technologies listed below were adopted in November 2017.{{cite web|url=https://www.itu.int/pub/R-REP-M.2410|title=Minimum requirements related to technical performance for IMT-2020 radio interface(s)|publisher=ITU|date=November 2017|access-date=28 August 2019}} Following the publication of the requirements the developers of radio access technologies such as 3GPP and ETSI are expected to develop 5G technologies meeting these requirements. 3GPP is developing radio access technologies 5G NR, LTE-M and NB-IoT that together are expected to meet all requirements,{{cite web|url=https://www.ericsson.com/en/blog/2018/12/lte-m-and-nb-iot-meet-the-5g-performance-requirements|title=LTE-M and NB-IoT meet the 5G performance requirements|publisher=ITU|date=9 December 2018|access-date=28 August 2019}} while ETSI is developing DECT-2020 NR and Nufront is developing EUHT (Enhanced Ultra High Throughput).
Requirements
The following parameters are the requirements for IMT-2020 5G candidate radio access technologies.{{cite web|url=https://www.itu.int/dms_pub/itu-r/opb/rep/R-REP-M.2410-2017-PDF-E.pdf|title=Minimum requirements related to technical performance for IMT-2020 radio interface(s)|publisher=ITU|date=November 2017|access-date=28 August 2019}} 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.
