KDDI moves to IP based network

July 18, 2005

Motorola announced that it has received orders in the 2nd quarter for its CDMA2000 1X SoftSwitch from Japan's KDDI for 3G cellular phone services. The SoftSwitch provided by Motorola will be used as the core switch in KDDI's CDMA2000 1X network.

Significantly more compact than conventional circuit switches, the Motorola SoftSwitch (MSS) minimizes the space and power required by telecom carriers. With this, significant reductions in capital investments and operating expenses are realized, leading to an increased competitive advantage for carriers in an increasingly competitive global market.

"To continue providing cutting edge solutions and services to our customers, we have been aggressively upgrading our network infrastructure. We expect that by replacing the existing circuit switches with the Motorola SoftSwitch, it will allow us to reduce operational costs on our network side," said Tadashi Onodera, president and chairman of KDDI Corporation.

"The award of this contract shows that the Motorola SoftSwitch itself has been highly valued by KDDI, and at the same time reflects their trust in Motorola over the past years., said Simon Leung, regional president, Motorola Asia Pacific.

In April 2002, KDDI began its nationwide deployment of CDMA2000 1X, a 3G cellular service, on Motorola's cdmaOne network. Since then, Motorola has played a vital role in building KDDI's wireless mobile network as the sole vendor of CDMA2000 1X RAN systems.

The MSS platform has been deployed as a full-featured serving MSC in greenfield, expansion and legacy switch replacement environments. The ability to provide telecom carriers a smooth migration without negatively affecting existing systems is a key driver behind its continuing success.
