LoRa SF{{ coverage.radio.sf }}, {{ coverage.radio.bw }} kHz (from the node's radio params): receiver sensitivity {{ coverageSensitivity }} dBm with {{ coverageFadeMargin }} dB fade margin, {{ coverageReceiver.gain }} dBi antenna {{ coverageReceiver.height }} m above ground. The signal fades with distance and where terrain gets into the Fresnel zone or blocks the path (ridges as knife edges). Crude estimate over terrain with forests (25 m trees). Single buildings and reflections are not taken into account.
