ETRI sets the global standard for NFC-based internet communication

Newswise — South Korean researchers have achieved a landmark achievement by setting the international standard for short-range wireless communication technology, typically used in the 10cm range, to enable Internet communication.

ETRI (Electronics and Telecommunications Research Institute) announced on July 21 that the international standard “IETF RFC 9428 (Transmission of IPv6 Packets in Near-Field Communications) It was officially adopted by the Internet Engineering Task Force (IETF), a semi-private international standardization organization under the Internet Architecture Board (IAB).

Near Field Communication (NFC), Low-power, two-way wireless communication technology has traditionally facilitated data exchange over a range of about 10 cm. It is mainly used in applications that require short-range communication, such as contactless payments, smartphone file sharing, and NFC tag information access. However, it was not widely used for wider Internet communication. With the introduction of ETRI's “RFC 9428” standard, the use of the Internet in short-range wireless communication environments is now possible.

By using NFC-based Internet communication, the payment environment between NFC devices can also use Internet-based communication. As a result, offline merchants can use existing NFC payment services without the need to install separate dedicated payment terminals.

While commonly used wireless technologies such as Wi-Fi and Bluetooth allow communication over relatively wider areas – with Wi-Fi covering up to 40m and Bluetooth up to 10m – the newly standardized technology communicates over an average range of 10 sm.

This makes it less susceptible to hacking risks compared to Wi-Fi and Bluetooth, thus providing a secure channel for data transmission in wireless communication environments.

In addition, this technology represents a unique achievement that is exclusively owned by ETRI's Standard Research Unit. Along with international standardization efforts, ETRI has secured two international (US) patents registered to the ETRI RFC9428 standard. This achievement is expected to be a cornerstone for bringing high-value results in future domestic and international markets for IoT-related payment and authentication services.

During the development of RFC 9428, the research team participated in interoperability testing organized by the European Union Telecommunications Standards Institute (ETSI), specifically the 6lo-6tisch plugtest in the IoT domain (IETF 6lo WG and 6tisch WG). Prominent international experts in low-power Internet communication technology conducted technical tests and demonstrations and achieved high scores. This validation of technical skills has gained international recognition and ETRI's technology has been introduced as the highest achievement in the Asia-Pacific Network Information Center (APNIC) sector of the International Telecommunication Union (ITU-T).

Kang Shin-gak, Director of 1ETRI's Standards Research Division, emphasized the importance of this international standardization and said, “The development of this international standard and the acquisition of standard patents are of great importance. It represents a valuable breakthrough that can drive innovation in the IoT field and pave the way for future market dominance.

In addition, this technology is envisioned by a group of researchers to find widespread use in various IoT environments, including smart homes, smart buildings, and smart factories, where various types of payments and communication environments that use contactless short-range wireless communication are required.

The IETF's regular meetings, which are held four times a year, are attended by experts from more than 50 countries, from global corporations, research institutes and academia, including Cisco and Ericsson, with a total of more than 1,500 specialists.

ETRI has a history of continuous standardization activities and research in prominent international organizations, including the IETF, where it has contributed to the development of more than 15 international standards, including Next Generation Internet Protocols (IPv6), mobile technologies, and IoT technologies.


ETRI is actively involved in standardization activities in international standardization bodies such as IETF and ITU-T to establish international standards in the field of IoT. This effort was supported by the Ministry of Science and ICT Information and Communications Broadcasting Standardization Support Project.
