Comparison of small-scale parameters at 60 GHz for underground mining and indoor environments

This paper describes the small scale performances of a 60 GHz channel in an underground mine and in an indoor laboratory using the same channel sounder. The frequency domain channel measurements have been carried out in the 59 GHz to 61 GHz frequency band. Based on the measurements, the two environments are characterized and compared in terms of delay spread, coherence bandwidth. The values of the delay spread are less than 3 ns for both environments. Finally a relationship between the delay spread and the coherence bandwidth is found for both scenarios.
