Could a wireless radio network save a miner's life

Leaky feeders are different. Instead of covering the cable in a solid copper shield, a leaky feeder has small gaps in the shielding to let the signal through. The gaps create a limited wireless radio network environment. Line ­amplifiers and repeaters boost the signal at regular intervals along the cable to make up for signal loss. Advertisement
