Australian Rail Operator Deploys TETRA Network in Central Queensland
Tuesday, October 17, 2017 | Comments

Radlink Communications secured a contract with Aurizon, Australia's largest rail freight operator, to deliver one of the largest radio networks in Australia. The network is due for completion early next year and will use TETRA technology, encompassing 79 sites and covering 2,670 kilometers of rail network, linking 50 coal mines and four major ports throughout central Queensland.

The new system will consolidate four outdated independent analog systems across Aurizon’s train control, shunting, maintenance and wayside operations into a singular cohesive TETRA network. The new network will provide the highest level of reliability and availability with no single point of failure, as well as deliver improved monitoring, remote diagnostics, overlapping radio coverage, GPS tracking and distress signal capabilities, a statement said.

Radlink’s technical solution uses Damm Cellular Systems radio base stations with Sepura radio terminals. The system will use Radlink’s digital radio software, a platform specially designed to provide advanced functionality and unlock the full potential of digital radio systems such as TETRA. Applications available to Aurizon will include geofenced auto channel change, weather alerts directly over the radio system, heat maps tracking every radio on a mapping display showing identity and location, speed alerts and signal strength, and a mobile phone client providing two-way radio access and functionality on smartphones.

“Installation of the project is running smoothly, with live testing producing seamless handover between neighboring sites and measured signal strengths vastly exceeding customer expectations,” said Radlink Project Manager Jimmy Whelan. “Since being awarded the contract in mid-February of this year, we have advanced to stage three of the five-stage project and are on schedule for our estimated completion in the first half of 2018.

“To ensure quality of service, we are replacing all components of the existing radio system and adding an additional 19 sites to the old Aurizon radio network.”

Telecommunications firm Radlink is providing a turnkey design and radio network solution including required towers, solar installations, system interfaces and applications.
