UNDERGROUND : reliable engine-to-ground communications in motion

Managing equipment and improving personnel safety in an underground mine require robust communications in an environment where the installation of wires is problematic and where radio waves propagation is limited by the topology of the tunnels.

For data exchanges, remote control and voice communications with the control room, ACKSYS offers a highly-available WiFi infrastructure solution with a reliable backbone to ensure an overall coverage of the underground mine and support the deployment of general IP applications.

ACKSYS’ rugged WiFi devices enable a trully uninterrupted communication thanks to :

  • a < 30 ms roaming
  • their wide power supply input answering power variations of long DC cables
