Tatara Systems Sells Mobile Broadband Product Line to Smith Micro Software

By Rajani Baburajan SIP Trunking Report Contributor

Tatara Systems, a company delivering Session Initiation Protocol (SIP)-based solution for femtocell network integration, has sold part of its mobile broadband product line to California-based communications solution provider Smith Micro Software. Financial terms of the deal were not disclosed.

As per the deal, Smith Micro Software acquired assets associated with Tatara Service Manager client software and the client management solution Tatara Subscriber Gateway. Smith Micro also assumed responsibility of Tatara’s facility in Vancouver, Canada.
E.Y. Snowden, chairman and CEO of Tatara Systems commented that the transaction enables Tatara to monetize the value of its mobile broadband products to apply those resources to femtocell convergence and applications enablement.
Femtocell, or micro cellular access points, promises to improve mobile voice coverage and deliver enhanced services to home and business users, while dramatically reducing cost.
Recent research from Informa Telecoms & Media found that the number of femtocells deployed worldwide by the end of 2013 could exceed the 40 million mark, with 22 million net additions in 2013 alone.
The research from also found femtocell installation could help operators to offload up to 8 percent of total mobile traffic to fixed networks via the end-user subscriber line, resulting in significant saving opportunity by reducing the need to create additional macro-cell capacity to cope with the amount of traffic.
Tatara Systems had raised an additional $6.5 million in May 2008 from Highland Capital Partners and North Bridge Venture Partners, bringing the amount of total capital raised by the company to $43.5 million till then.
The SIP-based architecture offers a number of advantages. While other radio access network-based approaches for deploying femtocells add to the load on and cost of the operator’s legacy circuit-switched mobile core, the SIP-based solution allows for the most cost-effective end-to-end femtocell deployment option, yielding OPEX/CAPEX optimization to recognize substantial savings, because it is the only method that offloads the legacy mobile core infrastructure, says Tatara.
At the core of Tatara’s SIP-based architecture is Tatara Convergence Server, which leverages a VoIP or IMS core to give any SIP-based end point presence on a mobile operator’s network. For femtocell applications, this ensures service parity with the macro network, while eliminating the need to tie radios directly into the mobile core, circumventing the attendant scalability and interoperability challenges, the company said.
