Push-to-talk-Over Cellular (PTT)
AMBE+™ Vocoder Technology
DVSI's 2200 vocoder technology is used in the iDEN (Integrated Digital Enhanced Network).
This all digital technology is a highly spectrum-efficient radio network that allows
users to easily and instantly communicate with one or many people at the push of
a button. The iDEN Push-To-Talk (PTT) service is available in the United States,
Canada, Mexico, Peru, Brazil, and Argentina. Cross-border PTT is also available
between users in Israel and Jordan.
DVSI technology helps extend the voice capability of a group’s secure network communications to anywhere broadband connectivity exists. DVSI’s software is integrated in apps that convert consumer smartphones or PCs into push-to-talk (PTT) devices that simulate and communicate with land mobile radios (LMR). DVSI’s AMBE+2 algorithm enables POC apps to help administrators who need to communicate with or track locations of team members without requiring additional LMR radios, providing a more economical path to noncritical safety communications such as P25, through the use of legacy system gateways or as a stand-alone system. Because PTT communication can be extended from a regional system to the nationwide coverage of a commercial carrier, utility companies, fleet services or railways, to name a few examples, have an alternative to traditional radio systems, or they can expand the functionality and coverage of the land mobile radio systems they’re using.
