Abstract :
RF channel measurements in mines have important applications in the field of mobile communications for improving operational efficiency and worker safety. This paper presents channel path loss measurements taken in a potash mine using a low cost RF channel measurement system. These measurements, taken at 915 MHz, are compared with a theoretical model. The measurements confirm that the mine tunnels can be modeled as oversized waveguides.
