Researchers in Japan have developed technology which delivers high-speed communications in excess of 10 Gbps, as required by 5G mobile communication formats. By controlling the phase of signals separately emitted from 128 antenna elements with high accuracy they have suppressed the interference between signals. This enables simultaneous communications in four directions using only one antenna panel. Signals can be varied in both horizontal and vertical directions expanding the communications area. With these developments, components can now be fit on a single 13 cm2 printed circuit board enabling the deployment of compact base stations and high-speed 5G communications in locations where many people gather, such as around train stations and in stadiums…read more.
