Keysight and Capgemini speed up NTN RAN validation

Regenerative NTN radio access networks (RANs) represent a significant leap in 5G technology. These networks amplify and process signals, enhancing communication quality and reliability. Testing regenerative NTN RANs presents unique challenges due to the need for seamless integration of terrestrial and satellite components, ensuring robust connectivity, and maintaining high performance across various environments.

Keysight’s UeSIM UE Emulation RAN solution effectively tackles the challenge of emulating multiple NTN-enabled user devices through its advanced integrated channel simulation capability. This solution allows the testing of NTN network protocols at scale, with precise orbit channel modelling, additionally enabling the realisation and demonstration of the NTN Beam Management concept. By leveraging Keysight UeSIM UE Emulation RAN solution, Capgemini successfully tested its 5G NR NTN RAN software (in regenerative and transparent architecture) for LEO/MEO/GEO constellation usage.

Rajat Kapoor, Head of Software Frameworks at Capgemini Engineering, said: “Capgemini's 5G NR NTN software framework is compliant with 3GPP Rel-17/18 and O-RAN based architecture, and helps to accelerate the development of various satellite based communication systems for different use cases for the satcom industry. The validation and interoperability of our 5G NR NTN software framework for transparent and regenerative mode with key partners such as Keysight are crucial milestones, enabling swift progress to meet the escalating demand for 5G NR NTN deployment.”

Peng Cao, Vice President, and General Manager for Keysight's Wireless Test Group, said: “Validating regenerative NTN RANs is crucial for advancing the 5G industry, as it ensures reliable and high-quality communication in non-terrestrial networks. Our collaboration with Capgemini Engineering addresses the complexities of satellite communication, supporting the development of innovative solutions for the market.”
