Mavenir And Terrestar Achieve Industry First Satellite Voice Over NB-IoT Call In NTN Mode

RICHARDSON, Texas, Feb 25 (Bernama) -- 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.
