Shaping the future with
“Millimeter Wave Technology ”
Fujikura Millimeter Wave Technology Contributes to High-Speed,
We at Fujikura see it as our mission to continue to help build communications infrastructure.
To this end, we continue to provide products that support consecutive technological innovations.
We build on technology cultivated over our 135-year history, starting with conductors and moving on to optical cables and wireless communications. Now we are developing millimeter wave (hereafter, “mmWave”) devices that incorporate our phased array antenna design technology, FPC production technology and electromagnetic field analysis technology.
In addition to developing a 60 GHz mmWave communications module with integrated an RF module and a BB module, we are also developing RF-ICs and Phased Array Antenna Module at the 28 GHz frequency bands. Our 60 GHz mmWave wireless communications module simultaneously achieves world top-class transmission speeds (max3.5Gbps) and long-distance transmission (> 500 m).
We also start developing band-pass filters and other low-loss, high-performance devices even for 70 GHz frequency bands and above.

CHALLENGES IN COMMUNICATIONS NETWORKS
Speed and Capacity Is an Important
Challenge for Society
Various applications such as video streaming and VR/AR games are widely spreading. These rich applications require high-speed and large-capacity communications, but the Sub 6 GHz frequency bands used in 4G is too narrow for these purposes. This is why mobile networks are starting to move from 4G to 5G. In order to achieve the features offered by 5G: the enhanced Mobile BroadBand (10 Gbps), Ultra-Reliable and Low Latency Communications (< 1 ms), and massive Machine Type Communications (1 million per km2), new broadband communication infrastructures using mmWave bands (e.g., 28 GHz, 38 GHz, 47 GHz, and 60 GHz) are being developed worldwide.

Beamforming technology required for 5G
Millimeter-waves have a wide bandwidth and
are necessary to meet 5G requirements.
On the other hand,the frequency used for 5G communication is 10 times higher than that of microwaves.
Millimeter-wave communication requires a different installation method and usages.
In conventional microwave band communication,
radio waves are transmitted and received in all directions.
In contrast, if the same method is used for mmWave communication, the radio wave strength will be reduced to about one-hundredth,and thus largely limit communication range.
So, for mmWave communication, beamforming is necessary to concentrate energy only on the communication target, condense the radiated beam, and follow the target.
Beamforming as desired is possible by controlling multiple antenna elements, called antenna arrays. The amplitude and phase of signals in antenna arrays can be set independently.
that applies beamforming technology.
