Press Releases

Fujikura Ltd. (President and CEO: Masahiko Ito) has begun providing samples of 60 GHz mmWave Wireless Communications Module that uses a "high gain phased array antenna" to achieve high speed wireless communication in the 60 GHz band. This is a compact, embedded module that integrates wireless protocol processing (baseband) functions with RF (radio frequency) circuit functions including an antenna.

Various applications such as video distribution and games using VR/AR are becoming widespread in society. This has created a demand for faster and larger capacity communications, but the Sub6GHz frequency band used for 4G is too narrow to achieve this.
To solve this problem, we developed a wireless communication module that uses the millimeter wave band, which can secure a wide bandwidth. The wide bandwidth that can be secured by the millimeter wave band increases communication speeds by an order of magnitude, enabling gigabit-class high-speed communication. However, since the millimeter wave frequency band has a large transmission loss, in order to maximize the characteristics of the wireless communication module, it is necessary to wire the RF-IC (integrated circuit) and antenna in the shortest distance. Therefore, we solved this problem by selecting a low-loss LCP (liquid crystal polymer) material for the RF circuit board and integrating the RF-IC and antenna into a module. This simultaneously achieves world-class communication speeds (>2Gbps) and long-distance transmission (>500m). In addition, the "4x16 element phased array antenna", developed using Fujikura's unique antenna design and electromagnetic field analysis technology, enables stable automatic beamforming with a wide angle of ±45 degrees. It also simultaneously achieves stable antenna characteristics that fully cover the 57-71GHz frequency band.

この無線モジュールは、通信ネットワークにおける「バックホール向け機器」 や「アクセスポイント（AP）」、「顧客構内装置（CPE）」、「V2X向け機器」等に適用が可能です。
当社は、本モジュールに加え、高周波対応製品の提供により5Gなどの高速無線通信ネットワークの構築に貢献していきます。
このモジュールのライブデモをバルセロナで開催されるMobile World Congress 2020 (MWC2020: Hall 5 stand 5E81）で行いますので、ご来場をお待ちしています。
※ライブデモの状況は、後日、下記URLに掲載をいたします。
