Advanced Simulation Technology inc. (ASTi), under contract with L3 Technologies, provided its Voisus voice communication equipment for the U.S. Air Force Research Laboratory's Secure Live, Virtual and Constructive (LVC) Advanced Training Environment (SLATE) project.

SLATE technologies integrate live aircraft, pilots in simulators and computer-generated forces to increase the realism and complexity of pilot-training. The new SLATE training radio with high-throughput waveform exchanges data between ground-based virtual (V) and ground- or air-based constructive (C) training components to systems on live (L) aircraft. Live aircraft can appear to sense, target and shoot at VC players as if they were real participants on the training range. This data lets participants train and hone their skills in a cost-effective environment.

ASTi's Voisus system ­– installed at Nellis Air Force Base's Nevada Test and Training Range (NTTR) in Las Vegas Valley, Nevada – offers a variety of capabilities to SLATE. One server gives it a fully digital Radio-over-IP (RoIP) connection to the Rockwell Collins live radios that are ED-137 standard-compatible and scattered hundreds of miles away from the server installation. This connection delivers receive/transmit digital audio and remote radio control to operators on the unclassified network.

Another Voisus server links unclassified RF voice traffic with four classified LVC network voice domains for cross-domain compatibility. This connection ties together aircraft-training at the live range and virtual/constructive network assets together. Voisus clients that use Defense Information Systems Agency (DISA) Secure Host Baseline Windows PCs can give NTTR operators access to all LVC communication assets.
