The core behind connectivity beyond the ground
Satellite NTN networks are moving from pilot to product: IoT devices reaching satellites directly, remote regions coming online, and phones connecting where no tower stands. But most of the market sells the satellite layer and leaves the network core as an afterthought. Connectivity beyond the ground only works if the core treats it as part of the same network — same subscribers, same policy, same standards.
Summa Networks gives providers a modular core built for that convergence — so satellite coverage extends your service instead of fragmenting it.
A core built for satellite NTN connectivity
Satellite and terrestrial on one core
NTN connects to the 5G core through 3GPP standards — so a device moving between a tower and a satellite stays on the same network, with the same subscriber profile and the same policy. Our 5G Core and Unified SDM give you one core across both, not two systems stitched together.
Ready for the models that are emerging
IoT over satellite, remote and rural coverage, direct-to-device — the connectivity models arriving now share one need: a core that adapts. A modular architecture lets you support new NTN use cases as they mature, without re-platforming each time the market shifts.
Modular by design — extend, don’t rebuild
Add NTN-driven services on the same core that runs your terrestrial network, with no forced bundling. The Full Core for Mobile, IoT, and Private Networks extends to non-terrestrial coverage as another model it was built to carry.
Reach beyond the ground, without fragmenting your network
The promise of NTN is reach — connectivity where terrestrial networks stop. The risk is fragmentation: a separate stack for every new coverage model, each with its own subscribers and rules to manage.
A modular Full Core keeps satellite, IoT, and terrestrial services under one subscriber and policy layer, so you extend where your network reaches without multiplying what you have to operate.
Built for the providers reaching further
Operators extending coverage
Reach remote and underserved regions by adding satellite coverage to the same core that runs your terrestrial network.
Satellite operators moving to 3GPP
Connect non-terrestrial access to a standards-based 5G core, so your service interoperates with the wider mobile ecosystem.
IoT and NB-IoT providers
Support devices that connect over satellite where terrestrial coverage ends, managed from one subscriber and policy layer.
MVNOs and new entrants
Build a service around emerging NTN models on a modular core, and add coverage types as the market matures.
