Fujitsu develops low power consumption tech for 5G

Fujitsu Laboratories built a prototype wireless unit incorporating inter-subarray coding technology. It helps to achieve high-speed transmissions for 5G mobile wireless base stations and access points in excess of 10 Gbps but consuming less power. In verification tests, the prototype successfully transmitted signals simultaneously to multiple devices. It has achieved these high speeds whilst maintaining low power consumption levels on par with Wi-Fi. Communication engineers are trying to implement 5G ultra high-speed communications by 2020 where the technology of millimeter waveband and multiple antenna elements is explored to simultaneously transmit signals as beams to each individual device. Currently, hybrid beam forming 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. Fujitsu Laboratories has verified the effectiveness of this newly developed technology that can reduce this interference. It limits the reduction in transmission speed while still achieving low power consumption. Keeping in mind the technological prospectus, users communicate at high rates simultaneously and with stability in an area with a high concentration of other users. ...
