RRA, Korea’s IoT Technologies Approved as International Standard of ITU (December 17)


National Radio Research Agency (RRA) of the Ministry of Science and ICT (MSIT) announced three recommendations developed by Korea have been finally approved as international standards in the ITU-T SG20 Meeting held in Wuxi, China from December 3 to 13.


ITU-T (International Telecommunication Union Telecommunication Standardization Sector): an international organization legislating international standard recommendations in the field of ICT utilization such as mobile, internet, network, IoT and big data and fee settlement.


ITU-T Study Group 20 (SG20): legislate and revise standards under ITU-T recommendations relevant to IoT and smart cities


“Framework of wireless power transmission application service(Y.4202)” technology was approved as the first international standard. This technology defines service framework providing wireless power to various IoT terminals that have difficulty in power supply.


- This standard technology includes requirements, reference models, service flow for defining service framework for providing wireless power transmission service. Therefore, it can be used in establishment of wireless power transmission service infrastructure in the future.


“Service functionalities of self-quantification over Internet of things(Y.4555)*” technology was approved as the second international standard. This technology provides support for information exchanges between self-quantification services developed by various companies in IoT environment.

* Self-quantification service quantifies personal health data (blood pressure, blood sugar level, body temperature etc.) and nearby environment information (weather, temperature, location etc.) to systematically analyze and come up with meaningful information.


- With this international standard technology, self-quantification services developed by different companies can mutually communicate which lead to utilization of various information such as personal health data including blood pressure and blood sugar level as well as nearby environment information including weather and temperature.

“Accessibility requirements for the Internet of Things applications and services(Y.4204)” technology was approved as the third international standard. This technology ensures the vulnerable class such as the disabled and elderly are not left out in the IoT environment due to digital divide by defining demands for accessibility.


- This standard allows the demands from vulnerable class such as the disabled and elderly that can arise from IoT environment to be identified, so that product and service development reflecting the needs from various consumer spectrums would be easy.


In regard to Y.4202 and Y.4555 which have been approved in this meeting, Electronics and Telecommunications Research Institute (ETRI) played a leading role in their initial launch and development. An ETRI researcher led the development of the two standards proposed in 2016 and contributed to making the standard draft and the final version.


SCE proposed the development of Y.4204 standard in 2016 and its development has been proceeded with close collaboration with ETRI.


Meanwhile, three new recommendations proposed by Korea including “visible light communication-based IoT service framework”, which are source technologies developed by ETRI will be approved in this meeting and developed in the future, with Korea playing a central role.


With respect to the approval of this standard, Mr. Jung Sam Young, Leader of International Cooperation Team of National Radio Research Agency (RRA) said, “we have established the foundation for providing interoperability in various IoT services and will actively respond by working together with experts from industry-academia-research institutes within Korea through follow-up standardization measures.”

In addition, Director Hyung Joon Kim of Standard Research Division of ETRI who played a leading role in the project said, “we will continue to develop standards for making various IoT services possible so that changes can be felt by the public and make sure to provide support to companies in Korea to take part in international standardization activities.”
