NTT to Visit the Yumesu Site of the Osaka and Kansai Expo
Decided to offer all-photonics network
Nippon Telegraph and Telephone Corporation decided on July 20, 2023 to sponsor "All Photonics Network (Below, APN)" for the Future
Society Showcase at the 2025 World Exposition (The following is the Osaka Kansai Expo.).
We will contribute to the success of the Osaka Kansai Expo by providing a network at the Yumesu venue that further evolves the APN
IOWN 1.0 currently being offered.

The NTT Group will provide APNs with low power consumption, highcapacity and high quality, and low delay transmission at the Yumesu
site of the Osaka and Kansai Expo 2025.
By connecting major facilities such as pavilions and event facilities inthe Yumesu venue, we provide a demonstration environment thatenables sharing of various contents and events in the venue, and asense of unity and immersion without feeling the distance.
We will further advance our communications services with theexperience and technological capabilities that the NTT Group has
cultivated, and by co-creating with our many partners, we will realize
an experience that is ahead of the future.

NTT, Chunghwa Telecom, and IOWN
Conclude a basic agreement for the realization
Nippon Telegraph and Telephone Corporation and Zhonghua Telegraph and Telephone Corporation (hereinafter referred to as Zhonghua Telegraph andTelephone Corporation have entered into a basic agreement for the realization of international network connectivity through IOWN on October 25, 2023.
In the future, IOWN's innovative communication technology centered on the All Photonics Network will enable international network connectivity
between Japan and Taiwan, as well as business and security cooperation related to IOWN.

Outline of the agreement
Based on their strengths in optical and wireless transmission
technologies, as well as NTT and Chunghwa Telecom's achievements
in implementing these technologies in society, we aim to realizeinternational network connectivity between Japan and Taiwan byutilizing IOWN's all-photonics network technology.
In addition, we aim to establish interfaces and international
connection rules for the realization of communication transparency ininternational network connections.

Future development
NTT and Chunghwa Telecom aim to contribute to a prosperous
society that can accept diversity through the realization of use cases
utilizing various IOWN technologies through international network
connections using IOWN technologies such as the All Photonics
Network, which is a robust communication infrastructure.
