Researchers from LG Electronics and Yonsei University have demonstrated full duplex radio technology based on an 80 megahertz multiple-input multiple-output broadband antenna at the electronics company's research and development campus.

Full duplex radio (FDR) is capable of doubling the frequency efficiency of existing networks.

The company said FDR is based on a broadband multi antenna technology called multiple-input multiple-output (MIMO), run on the 80 megahertz (MHz) frequency range. It also stressed that FDR can boost frequency efficiency in the fifth-generation (5G) network environment, compared to the existing time division duplex (TDD) technology.

LG expects that the FDD will be a major standard in 5G technologies.

FDR technology conducts multiple data transmissions in a single frequency range at the same time without time differences. By contrast, TDD technology is designed to send and receive with a time lag.

LG Electronics said FDR technology is expected to be particularly effective in frequency ranges under 6 GHz, in which the available bandwidth of frequency is limited.

5G mobile communications are expected to be commercialized in 2020. 5G offers 20 times significantly faster transmissions than the existing, LTE-based 4G technology, with a user experience transmission speed to be 10 to 100 times faster than 100Mbps, reaching the 1Gbps.
