High-speed, low-latency broadband internet

Developed by SpaceX, Starlink provides high-speed, low-latency broadband internet around the world. With satellites positioned in low-Earth orbit at an altitude of 550 km, over 65 times closer than conventional geostationary satellites, Starlink achieves significantly lower latency and higher transmission speeds for its end users.

KDDI will act as “authorized Starlink integrator,” enhancing the company’s ability to deliver best-in-class network service to its customers who require stable, reliable connectivity in rural and remote areas, even during events such as natural disasters.

KDDI will begin offering Starlink connectivity to its enterprise and civil government customers later this year.

Low-Earth orbit satellite

Developed by SpaceX, Starlink provides high-speed, low-latency satellite broadband internet around the globe. Starlink satellites are positioned in low-Earth orbit at an altitude of 550 km, so it can achieve significantly lower latency and higher transmission speeds for its end users.

For cellular backhaul

KDDI has selected Starlink for au’s 1,200 remote mobile towers as its network backhaul provider.

Using Starlink to backhaul service from these remote stations complements KDDI’s urban towers that utilize fiber for backhaul.

As soon as 2022, KDDI will be able to offer an urban mobile connectivity experience to its rural mobile customers. 

Starlink will enable communication speeds of over 100Mbps in mountainous areas and island areas, which were previously considered difficult to provide.

6,847 islands

It is said that there are 6,847 remote islands in Japan, excluding Honshu, Hokkaido, Shikoku, Kyushu, and the main island of Okinawa, and there are 254 inhabited islands alone.

No matter how remote an island is from the mainland, au will provide a high-speed mobile connection using Starlink.

16,667 mountains

here are 16,667 mountains on the 1:25,000 topographic map in the "Nihonzanmei Soran" (A Comprehensive Guide to the Names of Mountains in Japan). According to some theories, there are more.

No matter how steep the mountains are, we can provide high-speed communications from space.

And for the next 50 years

KDDI opened satellite communication centers in Ibaraki and Yamaguchi in 1963 and 1969, respectively, to handle Japan's international satellite communications.

For more than 50 years since then, we have been protecting and connecting Japan's satellite communications.

The ground station for Starlink service is installed at KDDI's Yamaguchi Satellite Communication Center.

We will continue to take on the challenge of the next 50 years of satellite communications.
