LTE R&D Services


Optimize costs and reduce the time-to-market of LTE and LTE-Advanced products with TCS’ LTE R&D Services and proven end-to-end product engineering capabilities.

The TCS Advantage

Our unique blend of hardware and software expertise enables us to manage your complete LTE product development and testing. We also bring the right solutions and alliance partnerships that provide you with a significant time and cost advantage in your product development lifecycle.


LTE R&D ServicesTCS’ services span architecture, design, development and testing for the following:

  • Protocols for UE and eNodeB (Macro, small cells) – PHY, MAC, RLC, PDCP, RRC and NAS
  • RRM and SON algorithms
  • Core network nodes like MME, SGW, PGW, PCRF
  • Management Systems – EMS, NMS, SON
  • Transport node

TCS has also built a number of solutions that support development and testing on LTE products:

  • Carrier Grade LTE PHY for eNodeB with support for both FDD and TDD
  • LTE Layer 2/ Layer 3 protocols stacks for eNodeb and UE
  • EPC Simulator to simulate the complete LTE core network
  • EPC Test solutions: Supporting scalability, performance and functional testing
  • Femto Gateway Test solution: Supporting scalability, performance and functional testing
  • LTE SON Platform (ANCO – Advanced Network Configuration & Optimization)
  • Small Cell OAM Test solution (TR-069 Support): Supporting scalability, performance and functional testing of the ACS/ Network Manager
  • Hetrogenous Network Plaftform: It offers  optimized use of network resources, with a high computing platform for radio control management that supports predictive analytics. The platform collects real-time data from user equipment and near-real-time OAM data from Element Management Systems (EMS), and factors these into decision-making for handovers. Download Brochure


  • End-to-end product engineering capability: Both for Hardware (RF engineering, System engineering, PHY Layer) and Software (Protocol stacks, EMS/NMS, SON, Platform engineering)
  • Ready-to-use solution accelerators/ frameworks: Product development and product verification solutions in LTE that bring down your costs (typically 30% TCO over 12-18 months) and time-to-market (typically 15%)


LTE PHY Solution

TCS’ LTE Layer 1 reusable components can be used for the development and validation of eNB and UE respectively.


LTE SON Manager

Telecommunication operators are spending large amounts to make their networks more competent as the network architecture becomes flat and networks organize themselves. New networks are evolving and resolving the issues faced by older network generations.


Small Cell OAM Tester

Wireless operators are preparing for exponential growth in mobile data traffic by increasing network capacity, providing mobile users with high bandwidth and high-quality experience by off-loading the existing licensed spectrum and minimizing power consumption. They see small cells and heterogeneous networks as the networks of the future. To make such a network cost-effective, its Auto Configuration Server (ACS) must be tested to make sure that its Operations, Administration & Management (OAM) capabilities meet the required functional and scalability criteria.


LTE EPC Test Solution

Long Term Evolution (LTE) is the next-generation, high-speed wireless broadband technology. Evolved Packet Core (EPC) is at the heart of an LTE network and is required to process massive amounts of data. It handles user data sessions with varied Quality of Service (QoS) and processes millions of control transactions per second. Hence, the EPC needs to be thoroughly validated throughout the product lifecycle in order to meet the operator expectations.
