In military operations, field personnel enter tunnels and other dangerous and hostile environments where traditional communications are unavailable. In these situations, for operational effectiveness and personnel safety, undetectable, portable, two-way communication is required both vertically and horizontally through the earth and man made obstructions.

Vital Alert systems provide portable, Through-the-Earth, covert voice and data communications via electromagnetic induction transmission. Vital Alert can integrate with existing field communication systems above and below ground. Our technology also supports text-messaging for environments where silence is a priority.
