Starent Networks Connects over 7 Billion Subscriber Data Calls; Starent Networks Celebrates Its Five-Year Anniversary and Success as the Leader in Mobile Data Infrastructure Deployments.

TEWKSBURY, Mass. -- Starent Networks, a leader in next-generation mobile infrastructure solutions, is celebrating five years of success and emergence as a leading provider of next-generation mobile data infrastructure. Since its inception, the company has deployed its ST16 Intelligent Mobile Gateway in numerous CDMA2000 and UMTS networks, connecting more than 7 billion subscriber data calls.

Starent Networks has made significant progress in establishing itself as a major packet core infrastructure provider by deploying its solutions in many of the world's mobile operator networks. Deployments include the world's largest 3G network with KDDI, Verizon Wireless' nationwide 1xEV-DO deployment and providing equipment to one of the fastest-growing U.S. operators, Virgin Mobile U.S. The company's customer list includes: China Unicom, KDDI, Movilnet, Rural Cellular Corp. (Unicel), SK Telecom, U.S. Cellular, Verizon Wireless, Verizon Wireless Puerto Rico, Virgin Mobile U.S., VIVO, Zapp Mobile and over 20 others.

Starent Networks has succeeded through its focus on enhancing the mobile subscribers' experience and the operators' profitability by delivering high-speed data, packet voice and multimedia solutions. Additionally, Starent Networks has distinguished itself by pioneering the concept of "In-line" services, which enables the integration of services at the edge of the network in its ST16 Intelligent Mobile Gateway.

To date Starent equipment has successfully connected more than 7 billion customer calls and continues to connect several million calls each day. These connections highlight the robust nature of the ST16 platform, which provides a call completion rate of over 99.999 percent at some of the most demanding tier one mobile operators.

"The Starent team has dedicated five years to solid strategy and execution," said Ashraf Dahod, president and CEO of Starent Networks. "Our success can be traced to our people who are dedicated to innovation. Deployment of our solutions allows mobile operators to offer high-speed data services while also positioning carriers to migrate to IMS/MMD core networks."

"With the proliferation of 3G wireless services across the globe, carriers are always looking to deploy future-proof solutions that seamlessly deliver next-generation voice and data applications," said Peter Jarich, principal analyst with Current Analysis. "Over the past few years, a number of start-ups have attacked the PDSN/GGSN space, but have faded from view. Starent's continuing success is a testament to the credibility of its products and capabilities."

This rapid adoption of Starent Networks' next-generation platform made it necessary to open offices in Asia, Europe, North America and South America, including four development centers. The company employs over 260 people. Starent also has more than 40 patent filings, continually pursuing the tradition of innovation and building on its performance leadership.

In five years, Starent has raised five rounds of funding totaling $95M and focuses on sustaining profitability. Starent backers include many of the world's most prominent venture firms such as, Focus Ventures, Highland Capital Partners, Itochu Technology Inc., Matrix Partners, North Bridge Venture Partners and Samsung Electronics Co. Ltd.
