KDDI‘s Backhaul Restora3on / Case Study 1

159 Starlink Kits
The earthquake resulted in extensiveﬁber op6c failures. During this period,
Starlink's satellite communica6ons
proved to be a reliable subs6tute
for backhaul infrastructure.

We extend our Heartfelt Gratitude
to SpaceX for 350 kits donation for theDisaster Relief , as requested by
the Ministry of Internal Affairs andCommunications in Japan.

SpaceX and KDDI provide Starlink free of charge.

Responses to Starlink's disaster relief in X
“Outstanding!
Exactly what we require at this moment.”“It's impressive how both technology and support
have advanced significantly!”“I've come to realize that communica3on is anindispensable lifeline, much like electricity and water.
It appears that the restora3on of communica3ons is
directly linked to disaster recovery.”By equipping an isolated shelter with Starlink,
an elderly individual managed to make a video callfor the ﬁrst <me in weeks following the disaster,and she was overwhelmed with joy and gra<tude
as she saw her grandchildren's faces.

Construction site
High-Rise Building
There was a challenge of no cellular networkat the construction site of a high-rise building.
Therefore, Starlink was installed at the top ofthe building to create a Wi-Fi environment.

Establishing a cellular network

within Bullet Train Tunnel
The challenge was that there was no cellularnetwork running through the construction site of
the Shinkansen tunnel and there was no way tocommunicate with each other. We are preparing
by utilizing Starlink to blow the cellular network
via satellite into the tunnel.
