Narus selected by KDDI for 3G EvDO service

April 19, 2004

Narus, a mediation system provider, announced it is expanding its focus into the mobile market through new business with long-time customer and Japanese 3G operator KDDI. As KDDI has evolved and grown into their revolutionary EvDO mobile network, Narus has been chosen to provide the mediation system for that growth.

KDDI shows how value-based 3G Services can succeed today

KDDI has been using Narus since it first deployed its CDMA2000 network in 2001. This network has grown to more than 10 million subscribers and Narus has been a part of that growth. With the launch of their EvDO network, KDDI has become the largest 3G operator in Japan. The Narus system is used by KDDI for the billing of KDDI's data services; a service which is leading KDDI's profit and subscriber growth as reported in their August 2003 company update report. The Narus system deployed by KDDI includes Narus' high-availability option, providing greater than 99.999% system reliability/uptime. This Narus system has exceeded these levels with 100% uptime, not losing any data or associated revenue in well over a year in production.

KDDI mobile data services to include revolutionary EvDO technology

As part of its continued effort to offer more value-based mobile services, KDDI is deploying Narus as part of its revolutionary CDMA 1xEvDO network that began commercial service in November 2003. On this network the handset can now achieve 2.4 Mbps (maximum) bandwidth, which provides true broadband data speeds to a mobile handset. The Narus high performance mediation system, which was chosen by KDDI and deployed by NEC, enables the world's most advanced and largest scale high performance mobile data services.

Narus solutions also provide tremendous billing flexibility, content settlement, and service and subscriber level intelligence, which are key for offering these new multimedia mobile services. By combining EvDO, which provides higher throughput/lower packet cost with Narus mediation, which provides this informational flexibility, KDDI will continue to strengthen its competitive position and will create a new wireless multimedia mobile society in Japan. KDDI is also increasing its existing CDMA 1x subscriber base and continues to add Narus software to its network to enable further network and subscriber growth.

"Asia continues to lead the way in new mobile services, and the successful examples of leaders like KDDI can be leveraged by mobile operators in Europe, the Americas and other regions," said Greg Oslan, president and CEO of Narus. "We are pleased that the leading companies in providing mobile services such as KDDI continue to look to Narus to help drive their success."
