It was a privilege to attend Raymond Lao's presentation on Unitywater's Telemetry SCADA Radio Network Upgrade at the recent ARCIA Brisbane event.
The presentation provided an excellent insight into the planning, design, implementation and operational challenges involved in upgrading one of South East Queensland's most critical communications networks, supporting more than 1,000 water and sewer infrastructure sites across a service area of approximately 5,000 km².
The project successfully transformed an ageing serial radio network into a modern Ethernet-based telemetry system, significantly improving network performance, cybersecurity, diagnostics, redundancy and operational visibility. The sheer scale of the rollout, involving more than 950 radio upgrades over a two-year period while maintaining continuous service, is a testament to the expertise and collaboration of everyone involved.
Goto Electrical was proud to be engaged as the project designer and to contribute to the development of a resilient, future-focused communications network for Unitywater. Working alongside Unitywater's operational technology and network specialists, ICA electrical contractors, Automation Group, and CyberCX, the project delivered substantial improvements in data throughput, network management capabilities and long-term reliability for this critical infrastructure asset.
What stood out most from Raymond's presentation was the transparency in sharing both the successes and the lessons learned, from managing large-scale rollout logistics and hybrid network architectures through to resolving RF interference and frequency reuse challenges. These insights are invaluable for our industry and demonstrate the importance of good engineering, collaboration and innovation in delivering successful outcomes.
Congratulations to Raymond, Ratna Geddam, Unitywater, and all project stakeholders on an outstanding achievement. We are proud to have played a role in helping deliver this important upgrade.
