Successful Japan-Europe Joint Experiment on Integration of Satellite Links in Japan-Europe Long Distance 5G Network

NICT has conducted a Japan-Europe joint experiment with Japan Radio Co., Ltd. (JRC), SKY Perfect JSAT Corporation (SKY Perfect JSAT) for connecting satellite and 5G, including Japan-Europe long-distance network. Successful transmission of 5G control-plane signal, 4K video, and IoT data was achieved in January and February of 2022 for the first time in Japan. This experiment was conducted in collaboration with the University of Tokyo, School of Engineering, Nakao Research Laboratory, the European Space Agency (ESA), Eurescom GmbH, and Fraunhofer FOKUS Institute.

This joint experiment shows that 5G communications can be established over long-distance links between Japan and Europe, including satellite links, and be expected to lead to the early spread of 5G networks in places where 5G deployment has been difficult, such as in the sky, at sea, or on remote islands.

Symposium on the Development of Frequency Resources 2021

The Association of Radio Industries and Businesses (ARIB) and the National Institute of Information and Communications Technology (NICT) will co-organize the Symposium on the Development of Frequency Resources 2021, under the theme of “Looking into the future ICT through Local (Rural) 5G and Beyond 5G / 6G” on July 9 at Meiji Kinenkan and on Zoom webinar.

As the 5th generation mobile communications system (5G) has been launched, expectations are growing for a local (rural) 5G service that will provide a self-employed 5G service that meets the communications requirements for specific areas and applications. In addition, technical studies and discussions have been initiated worldwide on next-generation mobile communications systems, known as “Beyond 5G” or “6G” for the wireless infrastructure that will support Society 5.0 in the future.

The symposium will focus on those wireless communication technologies that will lead to new forms of using frequencies. Experts from industry, academia, and government will give lectures on policies and the R&D, the standardization and expected use cases of the technologies. We look forward to your participation.

Successful international joint experiment between Japan and Germany in the field of space optical communication using a small satellite

NICT has conducted an international joint experiment with the German Aerospace Center (DLR) between the optical terminal (OSIRISv1) onboard the University of Stuttgart’s Flying Laptop satellite and NICT's optical ground station equipped with newly developed optical bench with fine-pointing system. In February 2021, a success in receiving the downlink light from OSIRISv1 at NICT's optical ground station was achieved.

At the same time, an initial experiment of the newly developed atmospheric turbulence measuring device was performed successfully. Furthermore, a successful demonstration experiment using a simple optical ground station composed of low-cost commercial parts was conducted by receiving laser light from the satellite.

The OSIRISv1 optical terminal uses body pointing for tracking and this is the first time a successful experiment with such implementation is performed in Japan. As a result, valuable experimental data that will contribute to the research and development of future space optical communication technology has been acquired.

Successful Experiment with Stabilization Technology for Wireless Communications for Manufacturing Systems

NICT and Toyota Motor Corporation (TOYOTA) have succeeded in experimenting with radio stabilization technology for manufacturing systems, and to have realized a "non-stop line". The "non-stop line" enables to detect unregistered terminals brought into manufacturing sites by visualizing radio waves, and also to suppress unplanned radio congestion for avoiding sudden interference by coordinated control of different systems. This time, we have demonstrated these technologies at two TOYOTA plants in operation.

In the future, TOYOTA plans to introduce this visualization technology to other factories sequentially in order to manage wireless systems at manufacturing sites properly. While, NICT will continue to demonstrate experiments of the technology at other TOYOTA plants, and to promote the research and development of the Smart Resource Flow (SRF) wireless platform, with the aim to put it to practical use at the plant.

FFPA Completes Technical Specifications to Stabilize Various Wireless Communication Systems Co-located in Factory Sites

Flexible Factory Partner Alliance (FFPA. Chairperson Andreas Dengel) has created the technical specifications that is aiming for various wireless systems co-located in factory sites to operate stably. The National Institute of Information and Communications Technology (NICT) has proposed Smart Resource Flow (SRF) wireless platform*1 which has been adopted as architecture for the specifications. By adopting this platform, stable wireless communication is realized, making it easy to visualize and interactively manage various information on the manufacturing sites.

The technical specifications define functions and interfaces to provide framework for coordination and coexistence of wireless systems with different standards, of different generations, and by different vendors coexisting in a same factory site.

An overview of the specifications will be presented at the FFPA seminar, “A vision of future factory sites created with the SRF wireless platform ~ Introduction of FFPA technical specifications Version1 ~ ” held on October 31 in Tokyo.

* Development of SRF wireless platform by NICT has been supported by the Ministry of Internal Affairs and Communications Japan for the project entitled “R&D on Technologies to Densely and Efficiently Utilize Radio Resources of Unlicensed Bands in Dedicated Areas” since 2017.
