Fujitsu's 300GHz, 10+ Gb/s receiver could transfer 4K and 8K videos 'instantly'

Fujitsu has revealed details of a new wireless receiver capable of data transfer rates of "several tens of Gigabits per second". Operating on the terahertz band, the receiver is over 100 times faster than current devices that use the 0.8-2.0 GHz range.

Described as "the world's first 300 GHz band compact receiver", the receiver is ten times smaller than previous models, opening up the possibility of use in mobile devices. Shrinking the unit has reduced its size to under one cubic centimeter and Fujitsu says that it "enables mobile devices to instantly transfer 4K or 8K HD video".

The need for greater bandwidth has become ever more pressing as file sizes increase due to improvements in image and video quality. High resolution video is very demanding of wireless connections, and Japan's Ministry of Internal Affairs and Communications commissioned a research and development project for the expansion of radio spectrum resources with a view to finding a solution.

While high-speed transfer devices have existed for a while, previous limitations meant that the receiver-amplifier module and antenna had to be separate. By integrating the antenna into the receiver-amplifier, Fujitsu was able to eliminate the waveguide component, but had to then develop a new low-loss polymide for use on printed circuit boards. Fujitsu says:

With mobile devices such as smartphones capable of high-volume communication at rates of several tens of gigabits per second, the use of this Fujitsu-developed technology will enable small devices to receive 4K or 8K HD video instantly, such as from a download kiosk with a multi-gigabit connection. It will also be possible to expand into such applications as split-second data transfers between mobile devices and split-second backup between mobile devices and servers.

Testing starts this year, and it is hoped that the technology will be commercially available by 2020.
