ETSI DECT-2020 authorized by ITU-R WP5D for subsequent revision of ITU-R M.2150 (IMT 2020)

ETSI DECT-2020 NR, the world’s first non-cellular 5G know-how commonplace, might be included within the subsequent revision of ITU-R M.2150, aka IMT-2020 know-how advice as per the conclusion of ITU-R WP 5D’s thirty ninth (digital) assembly on Oct 15, 2021.

[Separately, Nufront’s IMT 2020 RIT submission has been withdrawn for consideration in the next M.2150 revision, but maybe submitted in the future. The 5D SWG on Frequency Arrangements could not agree on a revision of ITU-R M.1036 Frequency Arrangements for Terrestrial IMT, which now can’t be approved till November 2022’s ITU-R SG 5 meeting.  That means there is no standard for 5G frequencies, which hasn’t bothered the FCC which is considering licensing frequencies that are not being considered for M.1036, e.g. 12GHz.]

The “DECT-2020 NR” Radio Interface Know-how (RIT) is designed to supply a slim however highly effective know-how basis for wi-fi functions deployed in numerous use circumstances and markets. It makes use of the frequency bands under 6 GHz recognized for Worldwide Cell Telecommunication (IMT) within the ITU Radio Rules.

The DECT-2020 radio know-how contains, however will not be restricted to: Cordless Telephony, Audio Streaming Functions, Skilled Audio Functions, client and industrial functions of Web of Issues (IoT) reminiscent of business and constructing automation and monitoring, and usually options for native space deployments for Extremely-Dependable Low Latency (URLLC) and big Machine Kind Communication (mMTC) as envisioned by ITU-R for IMT-2020.

In response to an e mail to this writer, ETSI helps this DECT RIT primarily due to its URLLC capabilities (3GPP Launch 16 URLLC within the RAN has but to be accomplished and efficiency examined).

DECT-2020 NR is claimed by its sponsor to be a know-how basis is focused for native space wi-fi functions, which will be deployed anyplace by anybody at any time. The know-how helps autonomous and computerized operation with minimal upkeep effort. The place relevant, interworking features to broad space networks (WAN). e.g. PLMN, satellite tv for pc, fiber, and web protocols foster the imaginative and prescient of a community of networks. DECT-2020 NR can be utilized as basis for: Very dependable Level-to-Level and Level-to-Multipoint Wi-fi Hyperlinks provisioning (e.g. cable substitute options);  Native Space Wi-fi Entry Networks following a star topology as in classical DECT deployment supporting URLLC use circumstances, and Self-Organizing Native Space Wi-fi Entry Networks following a mesh community topology, which allows to help mMTC use circumstances.

Dr. Günter Kleindl, Chair of the ETSI Technical Committee DECT, mentioned:

“With our conventional DECT commonplace we already obtained IMT-2000 approval by ITU-R twenty-one years in the past, however the necessities for 5G have been a lot increased, that we needed to develop a very new, however suitable, radio commonplace.”

Launched final yr and revised in April 2021, this ETSI commonplace units an instance of future connectivity: the infrastructure-less and autonomous, decentralized know-how is designed for large IoT networks for enterprises. It has no single factors of failure and is accessible to anybody, costing solely a fraction of the mobile networks each in {dollars} and in carbon footprint.

The IoT commonplace, outlined in ETSI TS 103 636 collection, brings 5G to the attain of everybody because it lets any enterprise arrange and handle its personal community autonomously with no operators anyplace on this planet. It eliminates community infrastructure, and single level of failure – at a tenth of the price compared to mobile options. It additionally allows corporations to function with out middlemen or subscription charges in addition to retailer and devour the info generated in the best way they see greatest becoming for them (on premises, in public cloud or something in between).

One other democratizing facet is the frequency. This new ETSI 5G commonplace helps environment friendly shared spectrum operation enabling entry to free, worldwide spectrums reminiscent of 1,9 GHz.

Jussi Numminen, Vice Chair of the ETSI Technical Committee DECT, explains:

“There’s plenty of discuss non-public networks however that is the primary 5G know-how which might help shared spectrum operation and a number of native networks in cell system frequencies. We see this as a elementary requirement for large digitalization for everybody. With the ETSI commonplace you get instantly entry to a free, devoted 1,9 GHz frequency internationally. It’s a good match for large IoT.”

Non-cellular 5G is constructed on utterly totally different rules from mobile 5G. One of many largest variations – and benefits – is the decentralized community. In a non-cellular 5G community, each machine is a node, each machine generally is a router – as if each machine was a base station. The gadgets routinely discover the very best route; including a brand new machine into the community routing works autonomously as effectively and if one machine is down, the gadgets will re-route by themselves. It means dependable communication eliminating single level of failures.

The usual fulfills each large machine-type communications (mMTC) and ultra-reliable low latency communications (URLLC) necessities of 5G. Reliably connecting hundreds and even thousands and thousands of gadgets is without doubt one of the cornerstones for demanding industrial 5G techniques. DECT-2020 NR helps native deployments with out separate community infrastructure, community planning or spectrum licensing agreements making it reasonably priced and straightforward to entry by anybody and anyplace.

A decentralized mesh with brief hops and small transmission energy additionally means a considerably decrease carbon footprint of the communications system. A current examine in Tampere College in Finland noticed an roughly 60% higher power effectivity at system degree in comparison with conventional mobile topology with the identical radio power profile.

The ETSI DECT-2020 NR commonplace consists of 4 components, printed in April 2021:

MAC: ETSI TS 103 636-4 V1.2.1 (2021-04)

PHY: ETSI TS 103 636-3 V1.2.1 (2021-04)

Radio reception and transmission necessities: ETSI TS 103 636-2 V1.2.1 (2021-04)

Overview: ETSI TS 103 636-1 V1.2.1 (2021-04)

Observe: Updates are being ready


This commonplace is effectively suited to companies reminiscent of good meters, Business 4.0, constructing administration techniques, logistics and good cities. It is going to help within the urbanization, constructing, and power consumption within the development of those good cities. It additionally opens alternatives for brand new use circumstances, scaling at mass the degrees of communication for the long run. The power transition from fossil fuels to electrical energy enhance native renewable power manufacturing and consumption market requiring new communication capabilities. This creates a round financial system and permits for the traceability of products, uncooked supplies and waste.

Finland-based Wirepas obtained €10 million in funding to develop and produce to market the primary know-how options for non-cellular 5G based mostly on the brand new DECT-2020 NR wi-fi connectivity commonplace introduced by ETSI in October 2020.  Wirepas mentioned it was the principle contributor to the event of the DECT-2020 New Radio (NR) commonplace.

ETSI DECT-2020 NR in a nutshell:

  • No intermediary
  • No infrastructure
  • No subscription charges
  • Free devoted worldwide frequency
  • Dense and big community capabilities
  • One tenth of the price of mobile
  • Lowest carbon footprint of large-scale networks

Editor’s Observe:  We’ve invited ETSI to submit an IEEE Techblog article offering extra info and functions for the ETSI DECT-2020 NR commonplace.
