Description:
"The electromagnetic noise that exists in a mining environment is quite severe and has been reasonably well-documented by a number of researchers. The noise level is such that prudent communication design requires the careful use of all the electromagnetic noise data available. A comprehensive survey was undertaken to determine techniques used in various industrial environments to achieve secure communications in the presence of electromagnetic interference. Several communication systems intended for use in a mining environment were examined, and the bit error rate as a function of distance was mathematically determined and plotted. The data communication protocol for these communication systems was examined and the probability of an undetected error versus distance was mathematically determined and plotted. The burst error detection capabilities are analyzed and presented. Conclusions and recommendations are presented for different communication systems, and significant mathematical developments and background information is included in the appendices." - NIOSHTIC-2
