ST Engineering iDirect has reported a recent demonstration that showed interoperability between its ground system and the 5G core. In the demonstration, a non-3GPP satellite network connected with the 5G ecosystem while appearing fully 3GPP-compliant, due to the company’s Interworking Gateway Function. 

ST Engineering iDirect called it a demonstration of its hybrid 5G NTN (non-terrestrial network) strategy, showing that satellite operators can leverage the efficiencies of the 5G core while still using satellite-specific waveforms. This type of hybrid connectivity can be used until the satellite-optimized 5G New Radio (NR) waveform matures. 

“Our goal is to create a unified, interoperable satcom network that enables seamless roaming between terrestrial and non-terrestrial systems, allowing customers to protect their existing investments while transitioning to a scalable, next-generation 5G NTN network,” said Sridhar Kuppanna, ST Engineering iDirect CTO. 

ST Engineering iDirect also said the proof-of-concept demonstrated inter-provider roaming, which allows operators to extend coverage to new regions and orbits. The company said the hybrid strategy is aimed at helping operators unlock new interoperability capabilities.

The company announced the capability ahead of World Space Business Week and will be offering demonstrations during the conference.
