This letter presents our experimental endeavor to characterize underground magneto-inductive channels. Specifically, a range of experiments are conducted in realistic underground environments, and the measurement data are compared with channel models established in prior publications. The channel model incorporates the impact of soil conductivity, is found in better agreement with the measurement data than models without soil conductivity included. It is therefore concluded that soil conductivity plays a significant role in underground magneto-inductive channels and must be modeled accurately.
