The customer is a leading US-based Wireless Infrastructure OEM
The customer wanted to develop a LTE base station solution, perform IOT and integrate EMS for Macro/ Micro eNB.
Tata Elxsi’s Solution
Tata Elxsi helped the customer in the development of eNodeB solution for both Macro and Micro form factors through Staff augmentation for L2/L3, QA, EMS, and OAM. The solution scope included:
- Enabling L2-L3 scheduler development (DL & UL both) from scratch, sector management, RRM, multi-UE scalability testing, MAC/RLC layer re-design and IOT
- Supporting EMS integration test, HARQ and multi-UE scalability tests
- Developing and integrating on-board OAM
- Tata Elxsi used VoLTE feature set delivery for this OEM with complete ownership
- A dedicated team of engineers developed features like DRx, IMS signaling, and SPS
- This activity also included integration and profiling of 3rd party ROHC stack
- Tata Elxsi also helped the OEM to achieve E2E voice call between two 3rd party UEs
Tata Elxsi, in one more engagement with this US based OEM, developed Multi-UE test tool with complete ownership for developing multi-UE Layer 1 on its L1 UE for TI 6670 platform.
We also performed Layer 1-2 integration & Layer 1 implementation as per architecture, which is scalable to 100+ UEs.
- The solution development involved all the activities from design, development, IOT and EMS integration that can be leveraged in the development/ optimization/ validation of similar solutions.
- The skillset developed in integration of Multi UE Layer-1 solution developed by Tata Elxsi is very rare & niche. This skillset and architecture expertise can be used as a reference for further scaling of UEs
