Tatara Systems Announces $7 Million Financing

Adoption of Company’s Architecture as Industry Standard and Pending Deployments Leading the Way for Further Expansion of Convergence Solutions

ACTON, MA – June 22, 2010 – Tatara Systems, the leader in SIP-based network solutions for femtocell convergence, today announced that it has secured a $7 million financing. The investment was led by North Bridge Venture Partners, a premier venture firm with extensive experience investing in communications software, equipment, and network infrastructure, with participation from Highland Capital Partners.

Femtocells, a disruptive new wireless communications technology initially viewed as an advanced in-building coverage solution, have increased in prominence recently as a principal element in addressing network capacity challenges and data off-load requirements accentuated by accelerating smartphone usage in both the consumer and enterprise markets. Tatara staked out an early leadership position in this market as the first vendor to announce an all-IP solution for femtocell convergence by introducing the Tatara Convergence Server, the industry’s first femtocell and fixed-mobile convergence application server.

The Tatara Convergence Server utilizes a flat, SIP-based architecture that allows for easier core network integration while providing a carrier grade platform that is highly scalable, is future proof to IMS and 4G, caps circuit switch investment by enabling off-load, and enables services beyond femtocell. Currently being deployed for both consumer and enterprise femtocell service in a Tier 1 CDMA carrier network, the Tatara Convergence Server also supports GSM/UMTS deployments. In March 2010, Tatara Systems’ SIP-based convergence architecture was adopted by the 3GPP2 standards body as the cdma2000 1x Femtocell Network standard. For CDMA networks, Tatara Systems has the only 3GPP2 standard compliant femtocell convergence server on the market today.

“With the explosive growth of mobile data and the evolution to 4G technology, mobile operators are faced with numerous challenges,” said Ed Anderson, managing general partner at North Bridge Venture Partners. “Tatara Systems’ standards-based platform addresses these challenges by offering operational efficiencies, substantial cost advantages and new revenue opportunities while leveraging both the legacy and next-generation network investments.”

“Tatara’s SIP-based convergence architecture has a competitive advantage within the femtocell market since it is the only solution available today that provides operators with the coverage and capacity benefits of femtocells together with the full mobile core offload and enhanced services revenue,” stated E.Y. Snowden, president and CEO of Tatara Systems. “Our Tatara Convergence Server is well positioned for further success in providing superior standards-based solutions to help address other convergence challenges faced by mobile operators.”
