In expansive mining environments, where critical communications are essential both above and below ground, VHF TETRA offers the ideal solution to consolidate multiple networks into one mission critical solution.
Above ground: VHF signals carry further in open spaces, enabling a cost effective but powerful TETRA solution that provides crystal clear audio even in loud, wet or dusty conditions. Below ground: With greater signal propagation, VHF TETRA is ideal for complex or expansive underground networks where safety is paramount.
MurrayWales, Principal Consultant at DXC Technology - Connect, and an experienced integrator of complex communication solutions, highlighted the value of the longer form frequencies: "When running large mines, organisations spread their operations across vast sites, often including ports or railway facilities, and across difficult or hazardous terrain. These could include mountainous and heavily forested areas, with variation between snow topped peaks and tropical vegetation. Torrential rain is a frequent operational hazard, as of course is the huge distance to first aid or maintenance support.
VHF TETRA offers an ideal solution to these organisations, improving coverage above and below ground and ensuring minimum risk to operations."
Ben Tabor, Product Manager at Sepura, explained how VHF TETRA radios improve outdoor coverage.
"Radio Waves in lower frequencies have longer wavelengths meaning they travel further distances in open spaces. Because of this, operators can reduce the physical infrastructure requierd to support the solution, enabling significant savings in equipment and maintenance costs."
The solution fills a notable gap in the market for quality VHF TETRA radios, complementing the reliability, secuirty, and mission critical protocols of TETRA with the powerful audio processing of the SC Series radios, ensuring crystal clear audio in loud, wet or dusty conditions.
