Tata Elxsi offers complete product development services along with a comprehensive suite of system software, reference designs and individual layers to help equipment vendors design and develop platform optimized and scalable solutions for eNodeB market.
The eNodeB solution is designed to support multi-core and multi-thread architecture, which enables easy integration with multi-processor platforms and third party software. Specially designed for customization, it exposes well defined interfaces for vendors to incorporate product differentiator algorithms in areas like Radio Resource Management, Scheduler, and Hardware Acceleration for crypto algorithms etc.
The LTE eNodeB software stack is compliant with the latest 3GPP Release 8 specifications. This includes components like PDCP, RLC, MAC, RRC, RRM and RoHC. The eNodeB protocol stack comes with a proven and highly-scalable architecture to support multiple variants. The high capacity variant supports Macro and Micro deployments with 20 MHz 4 x4 and above with dynamic load balancing capabilities. The low capacity variant supports Femto and Pico deployments with customizable architecture for meeting a given performance objective. Both the variants exploits the platform’s underlying hardware engines and programming model for optimized Data Plane / User Plane, MAC-PHY Interface and Scheduler implementation.
- Multi-variant support - Flexible and scalable architecture to support Femto, Micro and Macro deployments
- Platform optimized and efficient solution - designed to run on lesser cores and hence lesser power consumptionMulti core abstraction layer - for easy migration to other multi core processors
- CIL (Common Interface Layer) - for control plane configuration
- Ability of the stack to function only in user plane to verify scalability and system throughput
- Generic descriptor based MAC-PHY Interface - to support GiGE / PCIe / SRIO based physical interconnect
- SAP abstraction for inter layer communication - allows the integration of third party components and product differentiator algorithms
- Generic OAM interface layer - for system configuration, monitoring and evening purposes
- Extensive logging mechanisms for easy debugging and maintenance of the stack
