Communication Systems

Leaky Feeder Cables

• Leaky feeder cable is a radio frequency cable with weak shielding which allows radio signals to enter or leave the cable at any point
• A single cable carries several channels in opposite directions with a guard band between them to prevent collisions
• The cable has 16 intermod-free channels with super-low intermodulation noise levels
• Also, the cable is able to transmit wide-spread data and video signals making it ideal for voice over IP handset, WLAN, IP camera, remote blasting and PC connections

VHF System

• 30 meter radio coverage off of the leaky feeder cable
• 500 meter amplifier spacing
• Power supplies can be space up to 8,000 meters apart
• Local and remote diagnostics capabilities which can direct technical personnel to the problem area

UHF Systems

• 120 meter radio coverage off of the leaky feeder cable
• Minimizes the impairment of radio wave transmission in curves, branches, and other spatial limitations inside of a mine
• 350 meter amplifier spacing
• ATEX certified for use in mines at the risk of firedamp

Instrincally Safe System

• Allows for system use in mines or other hazardous areas where explosions are possible as a result of the surrounding environment
• Battery back-up allows for up to 4 hours of emergency power

Tagging And Tracking

• Locate personnel in an emergency situation
• Improve traffic flow and warn of approaching vehicles
• Monitor restricted areas and time spent underground
• Manage operations more effeciently
