TTP in Cambridge, UK, has integrated its satellite and systems design expertise with tools from Keysight Technologies to provide a digital twin of 5G satellite networks.

TTP is integrating its proprietary lab testing tools with Keysight’s PropSim Channel emulator and EXata network modelling suite alongside the Ansys STK physics-based modelling environment.

This combination enables TTP to offer a complete digital twin modelling, emulation and validation system for 5G non-terrestrial networks (NTN) that satellite operators, device manufacturers, app developers and network infrastructure providers can use to establish how their products and services will interoperate with the NTN network.

The digital twin and lab emulation platform will be demonstrated by TTP and Keysight at Mobile World Congress in Barcelona next week.

The testing environment can help validate solutions against 3GPP Release 17 NTN specifications. This includes end-to-end coverage of user terminal and antenna designs, satellite link budgets, regenerative payloads, ground stations and 5G core network components. The digital twin also includes full environmental modelling with detailed terrain analysis for real-time protocol measurements, real-time physics-based analysis, and user application modelling.

“Keysight’s digital twin solutions offer significant advantages to network operators in quickly rolling out technologies because they can be used to test the behaviour of their physical counterparts under diverse operating conditions. With this integration Keysight is enabling TTP to help the telecoms and satellite ecosystem bring NTN technology to the market faster,” said Peng Cao, Vice President and General Manager of Keysight’s Wireless Test group.

Adrian Hillier, Next Generation Market Lead at TTP says the digital twin will enable developers fine-tune 5G NTN innovation, ensuring more efficient satellite network deployments in the near future. 

“Using the digital twin, TTP’s radio engineering capabilities and Keysight’s testing and modelling technology, our clients and partners can explore system configurations for Regenerative payloads, model inter-satellite handover and terrestrial and non-terrestrial interactions, and ultimately, measure the quality of service experience for upcoming Non-Terrestrial Networks,” he said.;
