picoChip: Starent Networks, picoChip and Continuous Computing First to Demonstrate 3GPP Standard Iuh Femtocell Interoperability

TEWKSBURY, Mass., BATH , England, and SAN DIEGO, -- Starent Networks, Corp. (Nasdaq: STAR), picoChip and Continuous Computing today announced the industry's first demonstration of the new 3GPP Iuh standard which is critical to successfully bringing femtocells to mass market. These industry leaders will showcase a live demonstration of the 3GPP Release 8 Iuh interface between the 3G Home Node-B (HNB) and 3G Home Node-B Gateway (HNB-GW) at the Femtocells World Summit in London, June 23-25, 2009.

The emerging femtocell market provides an opportunity for enterprises and residential users to benefit from extended coverage for improved indoor quality of experience, cost savings for data usage as well as next generation multimedia services leveraging a femtocell's ability to determine presence, context and location. Standardization will allow operators to deploy femtocell and network equipment in a multi-vendor environment, thereby opening up competition, accelerating commercial deployments and lowering costs.

"Interoperability and standards compliance are crucial to the success of femtocell technology, and are important aims for members of the Femto Forum," said Prof. Simon Saunders, chairman of the Femto Forum.

The Iuh interoperability demonstration consists of: -- Starent Networks' ST40 platform supporting 3G Home Node B Gateway -- picoXcell(TM) femtocell silicon and PHY software from picoChip for 3G Home Node B -- Trillium femtocell software from Continuous Computing for 3G Home Node B

"The Starent Networks, picoChip and Continuous Computing Iuh interoperability demonstration is an important milestone," said Aditya Kaul, senior analyst, mobile networks at ABI Research. "A necessary condition for successful mass market adoption is true end-to-end open interoperability. Interoperability at such an early stage in the standardization process is a significant achievement, which indicates the level of commitment that the femtocell ecosystem has in working together, ultimately driving operator confidence in the technology."

About Iuh

The Iuh specification is a key component of an accelerated standards definition process undertaken by the femtocell community over the last 18 months with the aim of smoothly incorporating this genuinely disruptive technology into future communications networks. Iuh is important because it helps to solve the problem of how a very large number of small wireless cell sites (femtocells) can communicate back into an operator's network, and on to the global communications infrastructure.

Starting at the beginning of 2008, the Femto Forum took on the task of honing multiple, proprietary implementations of this key communications channel into a single recommendation. With the co-operation of the entire femtocell community it proved possible to present a proposal to 3GPP in time for incorporation in its Release 8 specification which was finalized in March 2009. Demonstrating interoperability between products from Starent, Continuous Computing and picoChip, three of the major players in the industry, represents a further milestone on the route to standardization.
