Abstract :
The paper presents a propagation characterization based on wideband radio channel measurements made in a mine at a center frequency of 1 GHz. The main attention is focused on the path loss and the delay profile analysis. The path loss has been found to be 40 dB/dec in a straight cave and 80 dB/dec in a curved cave. the delay spread was less than 0.5 μs. The radio channel in the mine proved to be non-reciprocal
