Modeling RF Attenuation in a Mine Due to Tunnel Diameter and Shape

Accurately characterizing the propagation of RF signals in tunnels is important for rescue, safety, and military purposes. The material composition of the tunnel, the tunnel shape and size, obstructions, and tunnel bends present challenges. In this paper we use Wireless InSite to analyze how tunnel diameter and shape affect the propagation characteristics.
