Fujitsu develops technology for low power consumption to 5G – Bitmag

The Fujitsu Laboratories, the arm of research of Fujitsu, has developed a prototype wireless built-in to the technology of encoding the inter-subarray of low energy consumption for transmissions of more than 10 Gbps in base stations (Cell sites) 5G, and access points. The prototype, according to the japanese manufacturer, keeps power consumption levels similar to that of Wi-Fi, even with speeds of 10 Gbps simultaneous transmissions to multiple devices.

While awaiting the definition of what will effectively be the standard of mobile communication 5G – the expectation of the International Telecommunications Union is to occur until 2018 – Fujitsu works with focus on the use of wave millimeter range, and multiple antenna elements to transmit simultaneously signals of beams for each device.

the prototype was able to was to decrease the interference in the sending of signals to multiple devices (beamforming hybrid). This method hybrid reduces the number of circuits (that consume a lot of energy) that control analog and digital, but at the same time, presents problems of interference and, consequently, reduction of transmission speed.
