RUCKUS Networks (Japan: Minato-ku, Tokyo; hereinafter RUCKUS) has announced that its Wi-Fi access points have been introduced as the network foundation for the public Wi-Fi service "d Wi-Fi" provided by NTT DOCOMO, Inc. (Headquarters: Chiyoda-ku, Tokyo; President: Yoshiaki Maeda; hereinafter NTT DOCOMO). To solve challenges of communication stability in high-density environments like stadiums and rapid spot deployment, NTT DOCOMO utilized RUCKUS's unique directional antenna technology, "BeamFlex+®". Furthermore, by combining this with network construction techniques using 5G millimeter wave and satellite communication "Starlink", they have achieved overwhelmingly short lead times for network construction without depending on traditional fiber optic installations.
### Background and Challenges: Balancing Quality and Speed in Crowded Areas
As communication becomes essential everywhere, such as for barcode payments and QR code entry confirmation, NTT DOCOMO aims to provide a more comfortable mobile experience to a wider range of customers and expand its economic sphere through "d Wi-Fi". However, at large-scale event venues, sudden congestion creates "walls of people" and radio interference, leading to concerns about the stability of connections with general access points. Additionally, for temporary spot deployment, the conventional method of using fiber optic lines posed significant hurdles in terms of cost and construction periods.
### Deciding Factors for RUCKUS: Dynamic Coverage and High Performance
To address these issues, RUCKUS Wi-Fi access points "R650", "T750se", and "T350" were adopted.
- Stable communication via "BeamFlex+®": By dynamically concentrating radio waves in the direction of devices, it avoids interference and achieves stable, high-speed communication even in harsh, crowded environments.
- Overwhelming lead time reduction: Combined with deployment technology using 5G mmWave and Starlink, they successfully deployed to a large event decided just one week in advance.
- Intuitive management: The GUI of the "SmartZone™" network controller is easy to operate even for non-experts, and is used for settings, evaluation, and analysis.
### Feedback from NTT DOCOMO
Regarding this introduction, Kojiro Oshita of NTT DOCOMO's Network Division stated, "We emphasized the benefits of RUCKUS products, which can respond flexibly and automatically to changes in the situation." Yuto Jinno, who utilized it on-site, highly evaluated its real-world performance, saying, "Once you enter the area, it maintains a solid connection, to the point where people ask, 'How does it stay connected even here?'"
### Future Outlook: Preparedness for Disaster and Next-Gen Standards
This solution is currently deployed at various regional branches nationwide paired with Starlink, contributing to a rapid support system for disaster-stricken areas during major disasters. In the future, with an eye toward supporting the latest standards like Wi-Fi 7, both companies will continue technical innovation to provide comfortable mobile experiences everywhere.
