Bangalore, India: Tata Elxsi has announced the availability of its 3GPP release 8 compliant LTE UE (User Equipment) protocol stack, enabling early delivery of LTE terminal devices and silicon solutions.

The stack leverages the company's experience in wireless technologies including CDMA, WiMAX, UMTS and EVDO, and is comprehensively tested and proven for conformance to 3GPP Release 8 specifications. The LTE UE solution provides complete software for Layer 2 and Layer 3, including MAC, RLC, PDCP, RRC and NAS. It also features optional LTE specific components such as RoHC v1/v2, Snow-3G, AES and Layer 1 algorithms.

The UE software architecture has been designed for minimized footprint and high performance and the overall architecture is split into control plane and data plane to handle critical and non-time critical operations, meeting the high throughput demands of LTE UE.

The solution has been modularly architected for SoC implementation, and is agnostic to the underlying Operating System and hardware. The LTE UE solution also features a multi-mode controller with intelligence for inter/intra Radio Access Technology (RAT) handover to enable backward compatibility to 3G. The solution has been integrated on an embedded platform and is ready for interop-testing with eNodeB solutions, ensuring optimum implementation and maturity.

It features comprehensive debug trace and statistical logging capabilities, and the descriptor-based MAC-PHY Interface enables easy adaptation of Tata Elxsi L2/L3 solution to third party L1 implementations.

"We have leveraged our expertise in the development, integration, interop and compliance testing for CDMA, WiMAX and 3G-based CPE and handset solutions, to deliver a software solution for LTE terminal devices. Our experience of implementing and integrating solutions on ARM and Tensilica processors provide customers with software and implementation services from a single partner. Customers can benefit from reduced costs, accelerated time-to-market and minimize development risks by accessing our solution," said Nitin Pai, vice president, marketing, Tata Elxsi.

Tata Elxsi addresses software, silicon and system design for wireless, networking, consumer electronics, automotive, semiconductor and broadcast industries.
