Tata Elxsi Extends Its LTE Stack

February 02, 2010 |

BARCELONA and BANGALORE, India -- TATA Elxsi today announced the availability of its 3GPP release 8 compliant LTE UE (User Equipment) protocol stack, propelling early delivery of LTE terminal devices and silicon solutions.

Tata Elxsi’s LTE UE protocol stack leverages the company’s deep 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 specially designed for minimized footprint and high performance. 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.
