Ultra-high-speed, high-capacity data instantaneous transmission within 10cm, close-range wireless communication technology
ETRI, which developed transmission/reception hardware/software, prepares the foundation for commercialization next year

As the current commercialized proximity wireless communication technology has limitations in transmission speed and capacity, interest in the ultra-high-speed proximity communication technology 'Zing' is growing.

Zing is a next-generation high-speed proximity communication technology that can transmit gigabit data between devices at close range, with ultra-high speed and low power transmission of 3.5 Gbps, and has emerged as a key communication technology in the Internet of Things (IoT) era.


In English-speaking countries, the onomatopoeia 'Zing', which refers to the sound made when an object passes quickly through the air, can be expressed in Korean as 'ssang'.

Zing' technology can transmit large amounts of data at 3.5 Gbps in an instant, and can respond to the low-power needs of mobile devices with energy efficiency that is 4,000 times higher than that of existing NFC technology. Accordingly, by holding the device up to a kiosk, desired data can be retrieved immediately, expanding the scope of use of short-range wireless communication, which was previously limited to extremely limited applications such as transportation cards due to limitations in data transmission speed. In other words, it will only take 3 seconds to transmit a 1Gbyte movie using next-generation high-speed short-range communication that does not go through the Internet.

3.5G instantaneous transmission technology 8,000 times faster than NFC

Recently, ETRI (Electronics and Telecommunications Research Institute) attracted attention by announcing that it had developed Zing, an ultra-high-speed proximity communication technology that can easily and quickly transmit and receive gigabyte-level large-capacity content within a close distance of 10 cm without complicated connection procedures.

The research team said that this technology has the advantage of being easy to commercialize as it uses low-power, low-complexity technology of 100mW (milliwatts), and it also uses the free unlicensed 60GHz frequency band, making wideband communication possible.

In particular, wireless power transfer allows you to conveniently use wireless storage devices without power supply, like USB storage devices, and allows for instant content transfer. In addition, since it is used in a secure communication area, it can block the possibility of hacking compared to WiFi, etc.

What the research team developed to implement the technology are hardware technologies such as modems, radio frequency (RF) transceivers, and antennas, as well as SW and system technologies, and they also developed prototypes of readers and tags necessary for data transmission and reception.

ETRI plans to develop a medical device that incorporates 'Jing' technology with Good Doctors Inc. If this device is developed, it is expected to be used to instantly send X-ray images of the oral cavity at dental clinics to a doctor's computer within 3 meters. 'Zing' technology can transfer gigabit content between devices instantly through an intuitive interface, so it can be used on smartphones, cameras, laptops, and other devices around the user.

Adoption of international standards, many applications including wireless storage devices and medical use

In addition, it can be applied to various products and services such as smart home appliances such as TVs and refrigerators, vehicle infotainment, smart IoT advertisements in shopping malls or on the streets, and subway kiosks, so its utilization as a communication technology in the IoT era is expected to expand.

Corp., which participated in this technology development as a joint research institute, plans to receive the Zing technology and develop chips and modules that can be applied to various business models.

In his case study on the development and use of IoT services utilizing the ultra-high-speed proximity communication technology Zing, Eun Ki-chan, CEO of Corp., said, “Zing technology provides a technology for instantaneous transmission of large amounts of data based on an intuitive user interface.” He added, “Since it can supply power wirelessly between devices, it can be applied to devices that do not require constant power supply, and it has the advantage of being easy to commercialize.”
