TriaGnoSys today announced that it has successfully demonstrated its VoCeM satellite communications compression software over Inmarsat’s BGAN network, and achieved good quality calls with a total bit rate of only 3.3 kbit/s. The test opens up the possibility of offering a low-cost satellite-based VoIP service with good quality voice.

The voice quality achieved during the demonstration was within the acceptable range for terrestrial mobile phone calls. This is particularly significant given the low bit rates used for the calls.

Axel Jahn, Managing Director of TriaGnoSys, said, “The demo last week was even more successful than we had hoped for in terms of the call quality. Our next job is to work with satellite-based VoIP and GSM suppliers to bring down call costs. In particular, we are in discussion with air, land and sea communications providers, since installing VoCeM requires only a simple upgrade.” . For the Inmarsat BGAN demonstration, TriaGnoSys used voice codec hardware containing a 2.4 kbit/s Digital Voice Systems Inc (DVSI ) AMBE+2™ vocoder , which TriaGnoSys integrated with its VoCeM compression and optimisation software.

Dr D V Ramana, Chief Engineer, Global Networks & Engineering, at Inmarsat who initiated the new voice codec activity said, “TriaGnoSys have done an excellent job in developing this system . This successful demonstration opens up a huge potential for offering low-cost VoIP calls over BGAN, backed by the reliability and global reach of the Inmarsat-4 network.”
