Reliable connectivity and communication is much more than convenience — it is necessary for the safety of people, vehicles, and overall performance. Tunnel Radio’s innovations and expertise in closed space communications, are next to none, and have been for over 30 years. Our patented technologies and customized solutions keep operations running efficiently, reliably and most important of all – safely. From design to installation, and even system maintenance, Tunnel Radio’s in-house team of experts know what customers need and back it up with second-to-none support.
Tunnel Radio’s fiber optic (FO) solution provides scalable and seamless connectivity under all conditions, especially for expansive operations.
Our patented ULTRACOMM® Distributed Antenna System has a range of 1,000 feet — more than triple the range of other systems.
For customers with relatively short term needs for advanced radio coverage in confined spaces, such as water tunnel inspections, our TempComm solution can be customized to your job and budget.
Unbroken simplex or duplex operation through the longest tunnels and most remote passes. All within the AAR 160 MHz band. Plus, Tunnel Voice is compatible with digital narrow band.
If you use LAN, our Ethernet Readers give you the features of Tunnel Radio’s powerful RFID system without a distributed antenna system.
Extend the 220 MHz signal through any length of tunnel or mountain pass, meaning you never lose sight — or control — of your trains.
Our network of amplifiers and distributed antenna cable extends the distributed power and end-of-train/head-of-train radio signals, keeping your systems connected from portal to portal.
TMS (Tunnel Monitoring System) relays network data to the server in a user-friendly format, so system health and status are easy to track from anywhere, any time.
TRCentral makes data on system performance, troubleshooting, and other information easily accessible through local networks or online remotely.
OFA connects to existing base sites wirelessly, with adjustable frequencies. It’s compatible with Tunnel Link and Tunnel Voice, and it can run on solar power if a wired power source is unavailable.
Customizable radiating coax (leaky feeder) solutions for safety and operational efficiency in underground and maritime infrastructure.
Customizable solutions for safety and operational efficiency in oil & gas environments.
We’ve worked with some of the biggest names in drilling, mining, and transportation.
Tunnel Radio creates leading-edge communication technologies that serve the needs of the mining, rail (freight), oil & gas, and public and private infrastructure markets.
