The performance of a ray-tracing model for received power prediction in an underground mine gallery has been presented. The error involved in the prediction is less than 6.5 dB. This error is less than the deviation observed during measurement. The sensitivity study clearly shows parameters which affect the model efficiency values. Also, the electromagnetic parameters (εΓ , σ) in the studied gallery...
This paper shows that a ray-tracing model focused on reflected rays can be used for power prediction in an underground area. The model is calibrated and then validated in scenarios where the received power prediction efficiency is confirmed by experimental measurements recorded along three distinct routes in the same gallery with the transmitting antenna located at three different locations. Different...
