Summary of the article Significant improvement in measurement accuracy and measurement time over three years [Seoul=Newsis] Reporter Jinyoung Lee = A Korean research team has developed the worlds first system that can measure the performance of 5G antennas at high speed.
In the past, most small antenna test facilities were used to measure 5G antennas, but in this case, it took about 200 hours to measure 5G terminals, and there were many difficulties in launching various new products in a timely manner.
According to the Ministry of Science and ICT on the 22nd, the National Radio Research Institute, an affiliated institution, has succeeded in developing a module that combines a measuring probe and a receiver into one through joint research with a domestic university for three years, and is expected to dramatically improve measurement accuracy and measurement time. A system was built in Naju and Icheon.
Looking at the development progress, ▲the 3.5GHz band measurement system in the first year ▲the 3.5GHz/28GHz dual frequency band measurement system in the second year shortened the measurement time.
In the 3rd year, by placing the previously developed core component modules in a circular structure with high density, it succeeded in reducing the measurement time to around 12 minutes by simultaneously measuring the radio waves emitted from 5G terminals in 360 degrees in all directions.
The National Radio Research Agency is promoting international standardization so that the developed high-speed measurement system and measurement technology can be widely distributed to domestic and foreign conformity evaluation testing institutes and manufacturers related to 5G new technology so that it can be used for conformity evaluation tests of new products. It plans to form a consultative body to support commercialization.
In addition, by applying this core technology to the terahertz band, it plans to conduct additional research so that it can be used complementary to the existing 5G measurement facilities.
In commemoration of the successful development of the 5G antenna high-speed measurement system, the National Radio Research Institute held an international workshop for 5G and future radio wave measurement attended by experts from domestic and foreign universities, industries, and measuring instrument manufacturers along with the opening event.
In his congratulatory speech, 2nd Vice Minister of Science and Technology Cho Kyung-sik evaluated that the development of the worlds first 5G high-speed measurement system is a significant step forward in the field of radio wave measurement, and at the same time served as an opportunity to raise the competitiveness of the entire 5G industry ecosystem.
