Wireless Mine Communication System

Additional information:  Since IWT was selected as the only vendor commissioned to develop and produce the equipment (with expected proprietary protections) under specifications defined by an agreement with the U.S. DOL--MSHA, there are no other vendors who produce wireless communication/tracking systems meeting the specific needs of mine rescue and that are compatible with the IWT equipment procured by MSHA.  While there are other vendors who produce general purpose underground communication and tracking systems for permanent underground deployment, those systems rely on permanently affixed infrastructure (cables)  to transmit and receive RF signals. These systems are susceptible to damage do not meet the reliability, compatibility, or operational requirements for mine rescue.
