Newtrax over leaky feeder
Multihop deployment in active face of mine for stope-level online tracking
Option of backhaul to surface via 1,200-9,600bps radio modem
Checkpoint deployment for zone-level tracking

Newtrax extension for leaky feeder backhaul

The Newtrax wireless communication infrastructure can be installed as an extension to leaky feeder because hundreds of two-way low data rate packet-switched connections can be maintained with a central server through a single circuit-switched 1,200-9,600bps analog radio data modem.
