NEC and TOPPAN Holdings begin joint demonstration as part of 5G co-creation activities
Accelerating co-creation activities toward social implementation of 5G/6G through demonstration results at NEC CONNECT 5G Lab
……
NEC Corporation (Director, Representative Executive Officer, President and CEO: Takayuki Morita, hereinafter referred to as NEC) and TOPPAN Holdings, Inc. (Headquarters: Bunkyo-ku, Tokyo; Representative Director, President and CEO: Hideharu Maro, hereinafter referred to as TOPPAN Holdings) With the aim of social implementation, we are promoting co-creation activities with the aim of combining NEC’s cutting-edge network and information processing infrastructure technology with the TOPPAN Group’s various solutions.
The millimeter wave band (28GHz band) used in 5G can transmit large amounts of high-quality information at high speed, so it can be used for monitoring remote areas, real-time high-definition video distribution, and television. It is expected to expand to various digital services such as conferences. However, because radio waves in the millimeter wave band are highly attenuated and travel in a straight line, there is a problem that communication quality tends to deteriorate due to the occurrence of dead zones where radio waves cannot reach due to buildings or other shielding objects. In response, telecommunications companies are taking experimental measures such as increasing the number of 5G base stations and relay stations, but the problem has not been resolved due to issues such as controlling cost increases and securing installation locations. not here.
To solve these issues, NEC has been conducting co-creation activities with various companies, universities, and organizations toward social implementation of the use of millimeter wave bands. On the other hand, TOPPAN Holdings has developed a lightweight and flexible
millimeter-wave reflective sheet with a metasurface structure that controls radio waves by utilizing design technology using
electromagnetic field simulation and high-definition etching technology cultivated through the manufacture of electronic
components. We have been working on the development of
The joint demonstration that will be carried out under this
co-creation activity will begin in April 2024. Specifically, the NEC CONNECT 5G Lab (*1) uses NEC’s 28GHz band local 5G base station (*2) and a designed millimeter-wave reflective sheet developed by TOPPAN Holdings to transmit 5G indoor radio waves. We will conduct an experiment aimed at eliminating the dead area. Last year, the two companies already conducted preliminary verification (*3) regarding the improvement of radio communication quality using millimeter-wave reflective sheets with no design features. In this demonstration, we will verify the effectiveness of improving communication quality in a test environment similar to actual use.
NEC and TOPPAN Holdings will strengthen co-creation activities from the perspective of exploring 5G/6G business based on the laboratories owned by both companies, NEC CONNECT 5G Lab and TOPPAN DIGITAL SANDBOX (R) (*4). . Through this activity, we aim to respond to the various needs of 5G/6G communication users, accelerate the social
implementation of 5G/6G and even “IOWN(R)” (*5) communication technology, and create new value. We will make suggestions.
For details on the joint demonstration to be launched, please see below. ■About the joint demonstration to begin
In the joint demonstration that will begin in April 2024, the NEC CONNECT 5G Lab will use a lightweight, flexible, and well-designed millimeter wave reflective sheet developed by TOPPAN Holdings with the aim of eliminating 5G indoor radio wave blind areas.
Implementation period: April 2024 to June 2024
Location: NEC CONNECT 5G Lab (Kawasaki City, Kanagawa Prefecture) Demonstration details: We plan to verify the effectiveness of improving communication quality using a millimeter-wave reflective sheet laminated with a wood-grain or marble-like decorative film in a test environment similar to actual use.

■About NEC CONNECT
It is a concept that represents an open co-creation space where ideas for the future are implemented in society using the power of digital, including networks. We promote co-creation based on the three themes of “connecting”: “Connecting the present and the future, Connecting people, and Connecting ideas and implementation.”
■About millimeter wave reflective sheet
The millimeter wave reflective sheet developed by TOPPAN Holdings is a lightweight and flexible sheet with a metasurface structure (*6). In the millimeter wave band used in 5G, it reflects radio waves in the desired direction, enabling high-speed, multiple simultaneous connections in dead zones where radio waves cannot reach. In addition, the reflective sheet has excellent design properties such as woodgrain and marble surfaces, and can be used as indoor wallpaper in offices and factory buildings without damaging the scenery of the office or factory. Masu. Furthermore, because it is lightweight, it is easier to install and construct than conventional heavy plate-shaped reflectors. https://www.holdings.toppan.com/ja/news/2023/06/newsrelease230627_1.html
