Damm Keeping Critical Operations Connected Across Africa
EXTENDING MISSION-CRITICAL COMMUNICATIONS ACROSS AFRICA’S TOUGHEST ENVIRONMENTS
When lives are at stake, communication cannot fail. From remote mining operations and rail corridors to utilities, municipalities, and public safety networks, maintaining reliable communications across vast operational areas has traditionally required significant infrastructure investment and complex network design.
Available throughout southern Africa from the Global Comms, DAMM’s VHF TETRA solution changes that by combining the resilience and security of TETRA with the extended range of VHF communications, delivering wider coverage with fewer repeaters.
PROVEN IN THE REAL WORLD
The world’s first VHF TETRA deployment took place in São Bernardo do Campo, Brazil, where mountains, forests, and large bodies of water presented significant communication challenges across more than 400 km2. The deployment demonstrated that mission-critical TETRA communications can be both practical and costeffective, delivering reliable coverage, crystal-clear audio, and secure communications while reducing the amount of infrastructure traditionally required.
The same challenges exist across many African operations, where difficult terrain, remote locations, and large operational footprints demand dependable communications every day.
WHY VHF MAKES THE DIFFERENCE
Unlike UHF, VHF signals travel further, making them ideal for large outdoor operations and complex underground environments.
This enables organisations to:
Extend reliable communications across larger operational areas.
Reduce infrastructure and maintenance costs with fewer repeaters and base stations.
Maintain clear voice quality, even under weak signal conditions.
Improve worker safety through secure voice and data communications.
Build resilient networks that perform when communication matters most.
DESIGNED FOR AFRICAN OPERATIONS
From open-pit and underground mines to rail networks, utilities, conservation areas, municipalities, and critical infrastructure, VHF TETRA delivers reliable coverage where conventional radio systems often struggle.
Organisations can also combine VHF and UHF, selecting the most appropriate frequency for each operating environment while maintaining one integrated mission-critical communications platform.
BUILT ON PROVEN TECHNOLOGY
DAMM’s robust, field-proven infrastructure, together with professional mobile radios from Sepura, delivers a complete communications ecosystem that has been extensively tested and continuously refined through real-world customer deployments. The result is reliable performance, operational efficiency, and long-term confidence in every installation.
