TriaGnoSys 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. 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.
