Breakthrough deployable via software upgrade to existing GEO satellites using available S-band spectrum to allow operators to monetize NTN services immediately

RICHARDSON, Texas, Feb. 24, 2025 (GLOBE NEWSWIRE) -- Mavenir, the cloud-native network infrastructure provider building the future of networks, and Terrestar Solutions Inc., Canada’s premier mobile satellite operator, have achieved a groundbreaking milestone by successfully completing an industry first Voice over NB-IoT (Narrowband Internet of Things) call in NTN (Non-Terrestrial Networks) mode. The achievement was conducted over a 3GPP-standardized NTN S-band spectrum, avoiding interference common in terrestrial networks. Designed to work with GEO satellite delays as well, the network ensures consistent coverage despite higher latency. This approach enables GEO operators to monetize NTN services immediately.

This industry-first call was made earlier in the year, January 2025, using standard codec, Sony’s Altair ALT1250 module, Mavenir Open RAN (Open vRAN and Open Beam radio), Mavenir Converged Packet Core, and was conducted in collaboration with Terrestar.

The successful VoNB (Voice over NB-IoT) call highlights Mavenir’s and Terrestar’s industry leadership in delivering innovative solutions that bridge the connectivity gap in challenging and remote environments. By leveraging 3GPP standards-based NTN technology, the collaboration is driving the integration of satellite and terrestrial networks to bring seamless connectivity to underserved regions, supporting IoT use cases and extending the scope of reliable communication.

Jacques Leduc, President, Terrestar Solutions: "Terrestar Solutions embodies innovation and leadership as the first MSS player to offer a real-time voice service based on a fully compliant 3GPP non-terrestrial network. With our dedicated S-band spectrum and an open network architecture, we leverage the strength of the 3GPP ecosystem to drive a breakthrough that sets us apart. Our mission: to accelerate the ecosystem development and provide all, through their mobile service provider, with satellite mobile connectivity that ensures security, autonomy, and independence."

Sachin Karkala, SVP & GM, RAN Business Unit, Mavenir: "Satellite services provide the perfect addition to existing terrestrial networks, adding a layer of widespread coverage, and nowhere is this more important than underserved and remote regions. This development allows satellite operators to launch voice services immediately using available spectrum, existing GEO satellites and industry-standard user equipment with a simple software upgrade to deliver voice services country-wide.”

This achievement paves the way for broader adoption of NTN-based NB-IoT solutions and further integration of voice services into IoT ecosystems as the standards progress. It also reinforces Mavenir’s role as a pioneer in delivering technologies that empower industries and communities worldwide.
