AMARISOFT: First NTN Rel17 5G NR end to end Call and Data Transfer over ASIA 9 geostationary Satellite.

Paris, 04/12/23 – AMARISOFT, a leading provider of 5G wireless network solutions, announces a major achievement with the successful completion of its first NTN Rel17 5G NR end to end Voice call and data transfer over the ASIA 9 geostationary Satellite. This milestone was accomplished using the innovative AMARI Callbox on the 5G network side and the AMARI UE Simbox on the user equipment side.

The AMARI Callbox, an SDR based 4G/5G Network solution was connected to the ground station payload in band n256. Simultaneously, the AMARI UE Simbox, an SDR based 4G/5G UE emulator, positioned on the user equipment side, was connected to the VSAT ground equipment, also utilizing band n256. The feeder link and service link employed the band Ku, showcasing the adaptability and versatility of AMARISOFT’s solutions. (see picture below for more technical details)

This achievement signifies a major leap forward in AMARISOFT’s readiness for NTN 5G NR deployment. The successful call and data transfer via the ASIA 9 Geo Satellite demonstrate the robustness and reliability of our 5G solutions in real-world scenarios, particularly in satellite communications.

As the industry continues to evolve, AMARISOFT remains at the forefront, providing innovative and reliable solutions that pave the way for the future of wireless communication. The integration of the AMARI Network solution (vRAN and 5G Core) and AMARI UE Simbox with satellite technology signifies a significant advancement in bridging communication gaps and ensuring connectivity in diverse environments.
