Digital Drift Leaky Feeder System

LEAKY FEEDER. RE-INVENTED.

Leaky feeder radio systems form the backbone of critical voice communications and safety systems in underground mines.

Despite this, the design of most line amplifiers is over two decades old.

THE SOLUTION

RFI’s amplifier design experts were tasked to re-invent this critical infrastructure.

Introducing the Digital Drift Leaky Feeder System - an innovative, ground-up re-design of the vital leaky feeder radio system.

The result delivers superior radio clarity, while also incorporating RFI’s Digital Drift technology, allowing high-speed Ethernet data to be natively transported over the same cable, without the complexity of cable modem technology.

IMPROVED AUDIO QUALITY

• Low noise figure operation:
• - Quieter, highly linear amplifier
• - Gain of up to 25dB, enabling 500m spacing
• Wide and flat passband

INCREASED RANGE FROM THE CABLE

• High RF power output (OP1dB > +17dBm)
• Consistent output power per channel, regardless of the number of simultaneous channels in use

LOW UP-FRONT INVESTMENT

• Inter-operability with existing amplifiers and cabling
• Upgrade existing radio networks to carry high-speed data
• Start small and expand as results are delivered

ONE CABLE FOR VOICE RADIO & HIGH-SPEED NETWORKING

• Native Ethernet support
• Proven high-speed data up to 800Mbps
• Integrates with existing underground fibre networks

LESS MAINTENANCE & NO ONGOING TUNING

• Self-adjusting gain management algorithm
• In-built self-diagnostics processor
• Simple cable terminations
• Easy installation and maintenance by site electricians
