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

This white paper uses Wireless InSite® (from Remcom) to calculate the attenuation of an RF signal at GHz for various tunnel diameters and shapes. The attenuation is calculated at 2.4 GHz and a Weilbull distribution is found that fits the propagation model. The propagation characteristics in our examples follow a Rician distribution.
