At only 1 kbit/s or less, our NESC codec enables efficient and robust voice transmission in areas where reception is only possible via direct-to-device satellite connectivity, making universal coverage a reality. NESC helps to facilitate NTN voice services over GEO, MEO and LEO constellations ranging from emergency services, audio messaging applications to satellite voice services that are comparable in quality to terrestrial calls. Fraunhofer NESC with its market leading coding efficiency is ready for commercial deployment at scale by SNOs and MNOs today.
