ST Engineering iDirect Milestone in 5G Non-Terrestrial Networks

ST Engineering iDirect, a prominent force in satellite communications, has announced a groundbreaking achievement in the realm of 5G technology. On September 3, 2025, the company revealed that it successfully created interoperability between its ground system and the 5G Core using its innovative Interworking Gateway Function. This crucial step allows a non-3GPP satellite network to connect smoothly with the 5G ecosystem, presenting itself as fully compliant with 3GPP standards.

This proof of concept (PoC) validates ST Engineering iDirect's ongoing strategy in hybrid 5G Non-Terrestrial Networks (NTN). The importance of this milestone is underscored by its potential to revolutionize global connectivity, enabling satellite operators to maximize the efficiencies offered by the 5G Core while still utilizing satellite-specific waveforms, including DVB-S2X and Mx-DMA MRC. Such a setup ensures reliability and performance without necessitating an immediate overhaul of existing satellite infrastructure. Operators can continue using their current systems while gradually stepping into new technological realms.

Furthermore, the PoC illustrated critical advancements, such as inter-provider roaming, which enhances global connectivity. This capability allows operators to expand coverage to new regions and orbits, creating opportunities for new revenue streams and speeding up the time it takes to bring new services to market. By enabling seamless interoperability across networks from multiple providers, the advanced capabilities of the 5G core improve operational flexibility, return on investment, and the ability to offer varied services. End users stand to gain from uninterrupted, secure connectivity and superior application performance.

Sridhar Kuppanna, the Chief Technology Officer at ST Engineering iDirect, emphasized, "Our goal is to create a unified, interoperable satcom network that enables seamless roaming between terrestrial and non-terrestrial systems. We aim to support customers in safeguarding their existing investments while transitioning to a scalable next-generation 5G NTN network. Our hybrid methodology is central to this strategy, and this proof of concept is a testament to our vision becoming reality."

Plans for further enhancements include the development of satellite-optimized gNodeB technology and 5G NR (New Radio) technology. These advancements will tackle the complexities associated with 3GPP access and hybrid User Equipment (UE) modems designed to switch seamlessly between non-3GPP and 3GPP systems. This progressive approach will empower operators, enabling them to unlock new interoperability capabilities essential for future advancements and standardization leading up to a more interconnected 5G-6G landscape.

In anticipation of World Space Business Week 2025 taking place from September 15 - 19 in Paris, France, ST Engineering iDirect plans to showcase this remarkable 5G NTN proof of concept. Interested parties will have the opportunity to schedule personalized demonstrations to witness firsthand the capabilities of this innovative technology.
