The NetNodeIS, Intrinsically Safe, is the latest adaptation of Cobham’s world-leading COFDM (Coded Orthogonal Frequency Division Multiplexing) wireless communications product range. Developed specifically for deployment in underground coal mines, the system can remain active and uninterrupted even when an explosive atmosphere has been detected, leading to improved production efficiency and miner safety.
The design of the NetNodeIS is based on proven Cobham COFDM technology currently used in demanding environments by military, government and broadcast organisations worldwide. The wireless mesh system is now offered with the European ATEX and the International IEC Ex M1 certifications, ensuring its intrinsically safe design and build quality. These standards permit its use in underground coal mining environments.
