Case Study: UHF Radio System Upgrade – Offshore Vessel
The Problem
One of our client vessels was experiencing poor UHF radio coverage.
The existing setup, a Passive Distributed Antenna System (DAS), was designed for standard radios.
But the vessel transported gas that required ATEX-certified radios for safety compliance.
The system wasn’t compatible, resulting in serious coverage gaps and unreliable communication.
Our Approach
We deployed a NET technician to assess the system.
The survey confirmed that while the DAS was complex, it wasn’t fit for purpose with ATEX radios.
We proposed a full DAS reconfiguration and the installation of two Motorola repeaters, customised to work with ATEX radios.
What We Did
- Installed and integrated Motorola repeaters into the existing DAS
- Reconfigured cabling and power dividers for improved signal performance
- Upgraded or replaced antennas, including ATEX-rated models in EX zones
- Reprogrammed ATEX radios for use with the new system
- Enabled Lone Worker monitoring, channel announcement, and noise cancellation to boost usability in noisy areas
The Result
The upgraded system was thoroughly tested and delivered on time.
Coverage was verified across all key areas.
Communication is now reliable, compliant, and robust, even in hazardous zones.
Our team worked closely with the vessel’s crew throughout.
The result was safer, more effective communication where it matters most.
