Interim Device Evaluations

The PSCR (Public Safety Communications Research) program has conducted a series of tests to evaluate the functionality of a collection of bridge, or audio gateway, technology products offered by various manufacturers.

An audio gateway device (also called an audio matrix or a cross-band switch) links disparate radio systems to support communications interoperability between dissimilar wireless systems. Such a device simply passes baseband (audio) signals from the receiver portion of one radio to the transmitter portion of a dissimilar radio system.

We have delivered the following evaluations on behalf of DHS/OIC (Department of Homeland Security/Office for Interoperability and Compatibility):
