This paper presents results from modeling RF propagation in a mine using Wireless InSite®. The Edgar Mine in Idaho Springs, CO provided the realistic scenario for the model. The path loss exponent was evaluated for a 5m section of the modeled mine by considering three different materials and three different standard deviation of surface roughness values for dry granite. When comparing this simulated data with data retrieved from the Edgar Mine it was determined that the Uniform Theory of Diffraction (UTD) ray tracing code, of Wireless InSite, can portray a communications system within a mine environment.
This paper presents results from sea to land propagation using Wireless InSite®. The effort explores the effects of various elements in the scene and how they impact the results. The various elements in the scene include the ships out at sea, the ships docked, the docks themselves, the buildings around the dock area, and the material properties of each.
