Communications & Tracking

The Smart Choice for Mining Communications & Tracking

IWT communications and tracking systems are designed for underground applications. Engineered to be highly reliable and extremely durable, our networks require little maintenance and make work safer and easier; all while outperforming Wi-Fi, leaky feeder, and text-based systems. The reusability, expandability, stronger signal and low maintenance provide an overall lower cost of ownership making IWT systems the smartest choice in comms and tracking. 

IWT’s ACCOLADE® and second-gen SENTINEL™ systems deliver the features and benefits that matter most to mine safety and operations:
