Fourth air interface technology added to 5G standards

Members of the International Telecommunication Union (ITU) today approved a fourth technology as part of ongoing standards development for 5G mobile services.

Known as “DECT 5G-SRIT”, the new technology supports a range of uses, from cordless telephony and audio streaming to industrial Internet of Things (IoT) applications, particularly in smart cities.

It was added in the first revision of ITU’s IMT-2020 key recommendation, which broadly encompasses fifth-generation, or 5G, networks, services and devices.

This ITU Radiocommunication Sector (ITU-R) Recommendation – which provides a set of global 5G technical standards – reflects ongoing consultation and discussion among governments, businesses, regulators and other stakeholders dealing with radiocommunications. in the whole world.

In addition to fostering cross-border connectivity, ITU promotes the global deployment of 5G as a key driver for achieving the 17 United Nations Sustainable Development Goals.​

“New and emerging technologies such as 5G will be key to building an inclusive and sustainable future for all people, communities and countries,” said ITU Secretary-General Houlin Zhao. “As part of the ongoing International Mobile Telecommunications or IMT program, our diverse members around the world continue their longstanding contribution to the advancement of mobile broadband communications, furthering our mission to leave no one behind to connect the world.”

A new radio interface technology

The ITU – the United Nations agency responsible for coordinating the world’s radio frequency spectrum – today released specifications for the new technology as Recommendation ITU-R M.2150-1.

The technology is designed to provide a thin but strong technical foundation for wireless applications deployed in a range of use cases, from wireless telephony to audio streaming, and from professional audio applications to industrial Internet of Things applications. (IoT), such as building automation. and monitoring.

The European Telecommunications Standards Institute (ETSI) has laid the essential groundwork together with the DECT Forum, a global industry association for digital enhanced cordless telecommunications (DECT) or cordless technology.

ITU Director of Radiocommunications, Mario Maniewicz, said: “The highly collaborative process involves substantial input and coordination with ITU Member States, equipment manufacturers, network operators, service organizations. standards development and the academic community. The ITU provides a unique global framework for discussing the capabilities of new radio technologies.”

Andreas Zipp, Chairman of the DECT Forum, welcomed the addition of the new technology to IMT-2020. “Inclusion in the ITU’s 5G global standards confirms the importance of this technology moving forward,” he said.

Other candidate air interface technologies have been through the International Mobile Telecommunications (IMT) evaluation process over the past year, although only one may be added at this stage.

The revised IMT-2020 recommendation now includes the new standard, which European standards developers say could support 5G adoption everywhere.

“The ETSI DECT standard received IMT-2000 approval over twenty years ago,” noted ETSI Technical Director Adrian Scrase. “5G therefore represented an ideal opportunity to develop this new non-cellular radio standard, particularly suitable for smart meters, industry 4.0, building management systems, logistics and smart cities.”

Based on the requirements defined in the ITU evaluation process, the air interface technology demonstrates worldwide compatibility in terms of operation, equipment and roaming. It also addresses the ultra-reliable low-latency capacity (URLLC) stipulated by IMT-2020 – the underlying global coordination framework for so-called 5G services.

About IMT-2020

IMT-2020 corresponds to the requirements issued by the ITU Radiocommunication Sector for 5G from 2015.

The large-scale commercial deployment of 5G networks only started last year, following the ITU’s publication of a key recommendation on radiocommunication technologies.

The ITU published the only globally accepted IMT standard for air interface technologies in February 2021 as Recommendation ITU-R M.​2150.

At the time of publication, three technologies meet the stringent performance requirements of IMT-2020. Two of them (3GPP 5G-SRIT and 3GPP 5G-RIT) were from the Third Generation Partnership Project (3GPP), while another (5Gi) was submitted by the Telecommunications Standards Development Society of India.

Collaborative assessment

The ITU solicited a wide range of input to ensure that the new recommendation would reflect the latest real-world requirements.

At the same time, ITU launched the development of IMT for 2030 and beyond, paving the way for new research activities. The ITU-R Working Party 5D, responsible for studying IMT systems, has begun to examine the future needs for the global adoption of the next generation of international mobile telecommunications. The upcoming World Radiocommunication Conference (WRC-23) hosted by the United Arab Emirates will address other aspects of IMT systems, among other topics.

“Even as 5G becomes mainstream, research is well advanced on the next generation of mobile networks,” Secretary General Zhao said.

About ITU

The International Telecommunication Union (ITU) is the specialized agency of the United Nations for information and communication technologies (ICT), which stimulates innovation in ICT with 193 Member States and more than 900 companies, universities and international and regional organizations. Founded more than 150 years ago, the ITU is the intergovernmental body responsible for coordinating the shared global use of the radio spectrum, promoting international cooperation in the allocation of satellite orbits, improving the infrastructure of communication in the developing world and to establish global standards that promote the seamless interconnection of a wide range of communication systems. From broadband networks to advanced wireless technologies, through aeronautical and maritime navigation, radio astronomy, oceanographic and satellite Earth monitoring as well as convergent fixed and mobile telephony, Internet and broadcasting technologies, ITU is committed to connecting the world.​
