A complete guide to underground DAS deployment for reliable 4G/5G coverage in mining tunnels using leaky feeder systems and RF engineering principles. Why Mining Tunnels Need DAS Coverage Underground mining environments are among the most difficult RF scenarios. Signal attenuation caused by rock layers, concrete, humidity, and metal equipment makes wireless coverage extremely challenging. In a 120...
