KDDI announces today that the first mobile tower in Japan to use Starlink has started commercial operation in Hatsushima, a remote island in Sagami Bay. Starting with this location, KDDI will expand its coverage to 1,200 remote towers in order to pursue its vision to bring an urban mobile experience to its rural customers.
Developed by SpaceX, Starlink provides high-speed, low-latency satellite 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. Using Starlink to backhaul service from these remote stations complements KDDIs urban towers that utilize fiber for backhaul.
KDDI has been conducting technical demonstrations of Starlink including for use in mobile backhaul since 2021. In order to ensure sufficient quality for cellular service with voice and data, Starlink has met the companys network technical guidelines in latency, jitters and uplink/downlink bandwidths. KDDI has completed its evaluation of Starlink and confirmed the conformance in customer experience that could be comparable to that of optical fiber.
KDDI will also offer Starlink Business to enterprise and civil government customers this year. With Japan having more than 16,000 mountains and 6,000 islands, with Starlink KDDI is now able to bring a new dimension of connectivity to Japanese society.
