Underground communications cover mines, tunnels, underwater passages, rails, pipelines, deep wells storages, burial sites, etc. Typically, wave transmissions are extremely difficult, due to all kinds of electromagnetic anomalies, such as alternation, absorption, blockage, reflection, diffraction, scattering, depolarization, noises and interferences.
In the United States, we have been invited by AMR (American Mine Research) in deploying our unique systems in AMR mines in West Virginia and Virginia. The results are exciting to the extent that AMR now uses Teletronics system for MSHA (Mine Safety and Health Administration) approval with a prospective of nation wide deployment. |
