An Empirical Study of Propagation Models for Wireless Communications in Open-pit Mines

Research output: Contribution to book/anthology/report/conference proceedingArticle in proceedingResearchpeer-review

Abstract

In this paper, we investigate the suitability of the
propagation models ITU-R 526, Okumura Hata, COST Hata
models and Standard Propagation Model (SPM) to predict
the path loss in open-pit mines. The models are evaluated by
comparing the predicted data with measurements obtained in two
operational iron-ore mining complexes in Brazil. Additionally, a
simple deterministic model, based on the inclusion of an effective
antenna height term to the ITU-R 526, is proposed and compared
to the other methods. The results show that the proposed model
results in root-mean-square error values between 5.5 dB and 9.2
dB, and it is capable of providing a close approximation of the
best predictions (i.e. those with lowest root-mean-squared error)
as provided by the SPM. The proposed model, however, reduces
the calibration complexity considerably
