Calabasas, CA, June 26, 2012 - Ixia (NASDAQ: XXIA), the leading global provider of converged IP and wireless network test solutions, announced today that Tata Elxsi has selected Ixia to validate their new LTE Small Cell software suite used in low-cost LTE home eNodeBs and enterprise femtocells and picocells. Ixia's IxCatapult test solution helps Tata Elxsi optimize the software suite functionality and performance, and will ensure Tata Elxsi provides high quality advanced features to their global customers.

Tata Elxsi's LTE small cell software suite enables system-on-chip (SoC) based implementations, including L1, L2/L3 and radio integration. The protocol stack for layer 2 and 3 is specially designed for small cell functionality, and has several improvements and optimizations to suit SoC architecture requirements.

The IxCatapult test system was used to fully validate the functionality and performance of Tata Elxsi's LTE Small Cell software implementation. By emulating LTE user equipment and generating both control plane and user plane traffic, the IxCatapult system is able to ensure software functionality, performance, error handling, and resiliency. Improved performance over macro cells is an important market driver for femto, pico, and micro cell access points  - Ixia's solution validates the readiness of LTE small cell devices to provide high quality services such as live conversational video.

Ixia offers the industry's most comprehensive 4G/LTE testing solution, measuring all aspects of 4G/LTE radio base station functionality, capacity, and performance. Ixia's wireless testing solutions accelerate the deployment and quality of mobile data services - from the wireless access, through the mobile backhaul, to the Internet core. By using real-world mobile subscriber modeling customers can perform service quality validation and measure subscriber quality of experience (QoE).

Key Facts:

• Ixia's wireless test solutions offer complete end-to-end performance testing of 3G and 4G wireless networks with a unique focus on subscriber modeling, QoE metrics, and multi-dimensional tests for capacity planning.
• Ixia tests all LTE eNode B variants, from femtocell access points to macrocell base stations, by emulating all surrounding nodes - including thousands of UEs/mobile subscribers, adjacent eNodeBs, the mobility management entity (MME), and the evolved packet core (EPC).
• Tata Elxsi offers fully integrated reference designs for 3GPP Release 8/9 LTE base stations on various silicon platforms, comprising of layer 2/3 and layer 1 integrated with radio.
