Temporary Tunneling Voice Communications

PBE engineers are the design and deployment experts of underground voice communications and are the most reliable in the tunnel construction industry.

Voice communications during the construction stage are normally provided by either Leaky Feeder or Wi-Fi. Both solutions can provide reliable and robust communications.

PBE’s Leaky Feeder System can be tailored to specific site requirements to provide the best radioPBE BDA-4 Tunneling coverage and data communications. The Leaky Feeder System is a tunnel radio system that can provide complete communications coverage for your site, including above ground surface coverage. This system can also include a connection to the local above ground telephone network via a telephone interconnect and integration into the emergency services mobile network.

Systems can be analog or digital, providing multiple channels and allowing complete operator control. Leaky Feeder systems have been a proven technology for many decades, although recent innovations enable Leaky Feeder to also become the backbone for vital monitoring and tracking systems.  PBE’s new BDA-4 amplifier not only boosts the signal along the cable but can be used as a tag reader, modem and in-line controller.PBE HEC-4 Tunneling

PBE provides a wide range of radio options for site, surface and underground linking and mine radio communications, including Motorola, Tait, and Kenwood two-way radios.

Wi-Fi can also be deployed to provide IP voice and data. This can form part of a fibre deployed network or use the Leaky Feeder backbone.
