It has achieved these high speeds whilst maintaining low power consumption levels on par with Wi-Fi. In verification tests, the prototype successfully transmitted signals simultaneously to multiple devices.

In order to achieve 5G ultra high-speed communications, for which development is ongoing with the aim of practical implementation by about 2020, attention is centered on technology that uses the millimeter waveband and multiple antenna elements to simultaneously transmit signals as beams to each individual device.

Currently, hybrid beamforming is being developed which could reduce the number of circuits, which consume a lot of power, by controlling both digital and analog circuits. However, this method has issues as interference occurs when sending signals to multiple devices, leading to reduced transmission rates.

With this technology, it is now possible for users in an area with a high concentration of other users to simultaneously, and with stability, communicate at high rates.
