Overview
The COM C200 is a through-earth communication system for long-range wireless communication in enclosed spaces such as mines and tunnels. It uses very-low-frequency electromagnetic waves and takes the ground itself as the propagation medium, building a communication channel between the underground station and a surface station for two-way voice, short-message and data transmission.
The equipment is intended for daily communication, data transmission and emergency rescue in coal mines, non-coal mines, tunnels and underground garages. It overcomes the difficulty of laying communication lines, or the loss of a wired link, and restores contact with people trapped underground after a mine disaster.
Very-low-frequency technology gives strong penetration and suits extreme environments such as mines and underground rail transit.
Wireless operation makes the system a dependable emergency communication link where infrastructure is unavailable.
Mine MA safety-mark certification and intrinsically safe explosion-proof design meet coal and non-coal mine requirements.
Flexible antenna technology keeps the footprint small and makes system deployment quick, and one unit serves both as a relay node and as a terminal connection.
IP67 protection rating for a rugged, durable and safe unit.
