Since its foundation, DSPG core competency has been focused on all aspects of Digital Speech Coding and Modem Technology, in particular for use in Mobile Satellite Communication. DSPG continues work in this area, being currently the only company providing independent technical support for AERO-H system used by most of commercial airlines.

As a spin-off from the Digital Speech Coding research, DSPG developed a range of testers to evaluate the voice quality of various voice related products. These testers gave foundation for a range of successful instruments including the BT Network Emulator, Echo Canceller Tester (ECT-1), DSPGenie, VoIP testers and others. Some of these products became the benchmark instruments used by many major telecommunication manufacturers and operators including Alcatel, Nokia, Ericsson, BT, HP, Nortel, etc…..
