Abstract

This paper presents comprehensive experimental results obtained from narrowband and wideband radio channel measurements in an underground mine with narrow veins at 2.4 GHz. From CW measurement data, large-scale distance-power curves and path-loss exponents of the environment are determined. Other relevant parameters such as mean excess delay, maximum excess delay and rms delay spread are extracted from wideband measurement data. Results show a propagation behavior that is specific for these underground environments with rough surfaces.
