Coverage Efficiency of Narrow-Band Wave Propagation in Mining Environments

This paper presents statistical and experimental analyses of narrow-band wave propagation at 2.4 GHz in an underground gallery. The aim of this study is to address the deployment issues associated with wireless communication systems of Wi-Fi wireless access points and their coverage. A genetic algorithm is used to produce all the numerical results present in this paper. Four known statistical models based on different cumulative distribution functions are used to compare these results with those obtained from experimentally. The models are applied to two different galleries in an underground area. Two performance evaluation criteria, the mean square error (MSE) and the Kolmogorov-Smirnov test, are used to comparatively assess models' efficiency. These are the MSE and the Kolmogorov-Smirnov test.
