Major telecommunications construction company MIRAIT ONE Corporation (head office: Koto-ku, Tokyo; President and Chief Executive Officer: Toshiki Nakayama; "MIRAIT ONE"), Rakuten Baseball, Inc. (head office: Sendai-shi, Miyagi; President: Yosuke Komeda; "Rakuten Baseball"), NTT Data Kansai Corporation (head office: Osaka-shi, Osaka; President: Masao Furuta; "NTT Data Kansai"), and GranBright Consulting (Head office: Yokohama-shi, Kanagawa; Representative: Hiroaki Noguchi; "GranBright") will jointly conduct a proof of concept (PoC) at the Rakuten Eagles Fan Festival 2022 to be held at Rakuten Seimei Park Miyagi on November 23, 2022 for the purpose of establishing a high- speed, high-capacity and low latency broadband network using the new "DX Wi-Fi®" and 5G, aggregating video from cameras installed in multiple locations over a wide area and using AI to analyze and display congestion and provide guidance to further increase the convenience of the stadium. Rakuten Mobile, Inc. ("Rakuten Mobile") will provide the 5G network infrastructure for the PoC.

A high-quality hybrid wireless network made using the new "DX Wi-Fi®" and Rakuten Mobile's 5G technology will be used for the wide-area high-speed wireless network used in the PoC.

"DX Wi-Fi®" is a product handled by NTT Data Kansai, which is sold, designed, integrated and maintained by MIRAIT ONE. The new "DX Wi-Fi®" supports Wi-Fi6 (IEEE802.11ax), and not only enables the creation of higher speed network environments than the original product enabling the creation of wide- area Wi-Fi environments over distances in excess of 500 meters, but is also resilient to line congestion and enables communication without load even when multiple devices are connected simultaneously. Video from cameras installed in multiple locations over a wide area in the stadium will be transmitted using this stable hybrid wireless network.

The aggregated video will be analyzed in real time using the WaitTime*1 AI congestion analysis solution on an edge server. It automatically identifies lines based on video of the restaurants surrounding the stadium, and estimates the number of people in the lines and the wait time. It also analyzes congestion at outdoor eating spaces and restrooms where congestion is anticipated. This PoC will verify the precision of these congestion analysis results, and verify how a smart stadium should provide the congestion information and implement operations such as guidance to enable visitors to enjoy themselves in comfort without stress.

MIRAIT ONE will proceed to consider full-scale implementation with Rakuten Baseball based on the results of the PoC, and plans to offer stadium solutions made up of networks and services utilizing the networks that increase the value of stadiums not limited to ballparks.
