Seung-Hyun Cho has been appointed Chair of IEC Technical Committee 103: Transmitting equipment for radiocommunication. He will head the TC until February 2025.
IEC TC 103 prepares standards on methods of measurement, safety requirements as well as transmitter control and interconnection of transmitting equipment for radio communication purposes.
The introduction of radio-over-fibre (RoF) technologies has changed the way IEC TC 103 works. Most of the new standards in preparation have something to do with RoF technology. One of the documents in development, for instance, deals with the frequency response of optical to electric conversion devices in high-frequency radio over fibre systems. Transmitting radio over fibre optic links reduces transmission losses and sensitivity to noise and electromagnetic interference compared with all-electrical signal transmission. Applications range from mobile radio signals including 5G and Wifi to the transmission of cable television signals, using digital compression formats such as 4 k and 8k.
To pave the way for RoF technology, IEC TC 103 requires experts with a strong background in optoelectronics and engineering. Seung-Hyun Cho not only meets that profile, he is also an experienced IEC and ITU expert. He obtained a Ph.D. degree in optoelectronic materials at the Hanyang University of Seoul in 2010 and started his professional career as a researcher for Korea Telecom before joining the Electronics and Telecommunications Research Institute.
He started working for the IEC in 2015 where he was the project leader for the IEC 62149-10 standard which establishes performance standards of RoF transceivers for mobile fronthaul systems, inside IEC TC 86. He became a member of IEC TC 103 in 2018 and joined the working group dealing with radio on fibre transmitters. He is also secretary of the SG 15 section of the ITU-T committee in Korea. CBI
