ST Engineering: Blueprint for a Connected Planet

The telecommunications landscape is evolving, with the lines between terrestrial and satellite networks blurring to deliver on the long-standing goal of truly ubiquitous connectivity.

At the heart of the transformation is 5G Non-Terrestrial Networks (NTN), a technology set to reshape global communications.

ST Engineering iDirect, a recognised provider of satellite ground infrastructure, is playing a pivotal role in advancing the shift, actively driving progress in the field.

With a rich heritage of more than 40 years in the satellite communications (satcom) sector, ST Engineering iDirect has established itself as a cornerstone of the industry.

Its extensive portfolio, marketed under the trusted iDirect brand, is synonymous with high performance and reliability across critical sectors, including mobility, broadcast and government.

Now, drawing on the insights of its leadership, it is championing a future built not on proprietary silos but on open standards and deep collaboration.

A paradigm shift for global connectivity

For decades, the worlds of satellite and terrestrial communications have operated in parallel, often as distinct and separate ecosystems.

The advent of 5G NTN, driven by the standards set out by the 3rd Generation Partnership Project (3GPP), is set to demolish the walls between them. By design, the framework weaves satellite capabilities directly into the fabric of the global 5G network.

Sridhar Kuppanna, CTO at ST Engineering iDirect, frames the shift as a pivotal moment for the industry.

“Until recently, satellite and terrestrial communications existed in largely separate realms, but the introduction of 5G NTN, spearheaded by the 3GPP, changes that,” he explains. “The 5G NTN standard as defined by 3GPP allows for seamless roaming between satellite and terrestrial networks, enabling more reliable, consistent and global connectivity than ever before.”

For telcos, the integration offers a paradigm shift. It means the ability to extend service coverage to the most remote and previously unreachable locations on the planet, from maritime routes and aeronautical paths to rural farms and isolated industrial sites.

The expansion is not merely about plugging coverage gaps. Instead, it is about creating new revenue streams, enhancing network resilience by providing robust backup paths and enabling sophisticated enterprise services on a global scale.

As 3GPP standards continue to mature with Releases 18 and 19, the satellite is cementing its role as a core, indispensable component of the unified 5G ecosystem.

The critical imperative of standardisation

The realisation of the immense potential of 5G NTN will only be when the industry collectively embraces standardisation.

Historically, the characterisation of the satcom industry was through proprietary hardware and software.

While effective, the approach created fragmentation, making integration between different systems complex, costly and slow, a significant hurdle in highly regulated and hardware-intensive sectors like aviation.

Standardisation, as championed by 3GPP, provides the common language necessary for disparate systems to communicate fluently.

It democratises the technology, reducing vendor lock-in and fostering a more competitive and innovative marketplace. Sridhar highlights how standardisation directly empowers operators.

“5G NTN is redefining what’s possible for telecom operators by removing traditional infrastructure barriers,” he notes. “Features like network slicing enable tailored, high-performance services for use cases such as enterprise broadband and mobility, but IoT and public safety.”

The standardised approach streamlines billing, roaming and network management across both terrestrial and non-terrestrial domains.

It paves the way for true interoperability, not just within the 3GPP framework but with non-3GPP satcom systems, creating a scalable, integrated global network that is far greater than the sum of its parts.

Collaboration as the engine of progress

Adopting robust and universal standards is not a solitary endeavour, it hinges on collaboration.

As Sridhar points out, “Standardisation doesn’t happen in a vacuum. It requires a coordinated effort across multiple stakeholders, including satellite operators, telecom providers, terminal manufacturers and cloud service platforms.”

The collaborative ethos extends beyond the crucial work within 3GPP.

A constellation of industry consortia is playing a pivotal role in translating standards into real-world applications. Bodies such as the Seamless Air Alliance (SAA), the Digital Intermediate Frequency Interoperability (DIFI) consortium, the WAVE Consortium and MEF are bringing together diverse market expertise to solve specific integration challenges and accelerate adoption.

A recent milestone perfectly illustrates the principle in action. In partnership with the European Space Agency (ESA), the SAA demonstrated the first-ever aviation use case for 5G NTN, showcasing seamless, gate-to-gate multi-orbit connectivity built upon 3GPP standards.

This tangible success story illustrates how cross-industry collaboration has the potential to transform theoretical standards into demonstrable value, paving the way for the next generation of in-flight connectivity.

Charting the course for a connected future

The journey to full integration 5G NTN world is a marathon, not a sprint.

It demands a sustained commitment to collaboration and a shared vision for a truly connected planet.

For ST Engineering iDirect, it is more than just a business strategy: it is a core mission.

It not only adopts standards but actively helps shape them, ensuring its next-generation, cloud-native ground systems like Intuition are ready for the industry’s integrated future.

As Sridhar concludes, the company’s commitment is unwavering.

“We are actively involved in the 3GPP standard bodies, ensuring a seamless integration of our multi-orbit satellite system with the 5G core by supporting 3GPP standards. We are proud to be at the forefront of this movement, working closely with industry leaders to shape the future of global connectivity,” Sridhar concludes.
