Tunnel Communications Systems

Providing reliable tunnel communication

For clear communication in underground mines and tunnels, one tried and tested solution is a leaky feeder network. Also known as radiating cable, leaky feeder cable will be installed throughout a tunnel and will feature gaps in its outer conductor that allow radio signals to leak in or out. This allows for wireless communication between radio receivers, such as handheld radios or fixed phones.

Portable, wireless communication solutions for tunnels and rescue

Sybet’s portable communication solution is the only viable solution for rescue operations, or for exploration or maintenance of underground spaces such as viaducts, waterways and dams where there is no static communications infrastructure in place. Sybet’s systems use groundbreaking technology to ensure reliable communications between underground and the surface.

  Radio communication in tunnels

  Tunnel wireless communication means that workers can communicate from any part of the tunnel network.

  Pyott Boone, or PBE Group, offers a wide range of leaky feeder systems that enable radio communication. From conventional leaky feeder systems to a CMTS system, permanent radiating cable network or hybrid networks, PBE provides cable installation and an extensive product portfolio of radios and atmospheric monitoring devices that can be incorporated into the network.

  Caroll Technologies distributes the Pyotte Boone Page BossTM mine page phone series, which is one of the most reliable and advanced range of phones available to the tunnelling and mining industries.

  • The 112S/S Standard GEN II Model 112 page phone features a sounder strobe for increased audible and visual alerts in noisy working areas
  • The model 111 Page Boss is fitted with a bullhorn speaker, 110 or 220 VAC power supply and 12VDC output.
  • The model 140 Page Boss features a touch-tone keypad that can make calls through Model 139 or operate as a standard 12 VDC paging phone

  Carroll Technologies also supplies Pyott Boone leaker feeder cables and VHF leaky cable, as well as a range of power supply solutions, amplifiers, couplers, connectors and termination boxes.  With a comprehensive range of leaky feeder cables and system units, Carroll Technologies can supply a fully customized tunnel communication system, and as a factory-certified repair center for Pyott Boone equipment, Carroll ensures these systems are always running efficiently.
