By securing core 5G technologies and increasing the efficiency of limited frequency resources, we anticipate trillions of dollars in economic value.

On the 29th of last month, LG Electronics jointly developed and demonstrated the world's first 80MHz bandwidth, wideband multiple antenna (MIMO, Multiple Input Multiple Output)-based 'FDR' communication technology with Yonsei University (Professor Min Byung-wook), thereby securing a lead in the core 5G technology.

'FDR' communication technology can increase frequency efficiency by up to two times compared to existing 'FDD (Frequency Division Duplex)' and 'TDD (Time Division Duplex)'.

LG Electronics, which has been developing "FDR" technology since 2014, successfully demonstrated "FDR" technology operating at the LTE frequency bandwidth of 20MHz in October of last year. This year, it successfully demonstrated "FDR" technology at the 80MHz frequency bandwidth, a key requirement for the 5G standard.

The "FDR" technology demonstrated by LG Electronics is a promising candidate for the 5G standard, capable of dramatically increasing data transmission speeds. It is particularly useful in frequency bands below 6 GHz, where available bandwidth is limited. Considering the high auction prices for limited frequency resources, the improved frequency efficiency enabled by 'FDR' technology is expected to create economic value worth trillions of won or more.

This demonstration integrated the individual antenna, analog, and digital technologies required to achieve FDR into a single system. Furthermore, it incorporated multi-antenna technology (increasing the number of transmit and receive antennas to two or more) to further enhance frequency efficiency.

LG Electronics Vice President Kwak Kook-yeon, head of the Next Generation Standards Research Institute and CTO Division, emphasized, “By securing the ‘FDR’ technology, which is expected to be a key 5G standard, we will continue to strengthen the competitiveness and influence of future 5G standards.”
