Through-the-earth mine communications - Wikipedia

Through-the-Earth (TTE) signalling is a type of radio signalling used in mines and caves that uses low-frequency waves to penetrate dirt and rock, which are opaque to higher-frequency conventional radio signals. In mining, these lower-frequency signals can be relayed underground through various antennas, repeateror mesh configurations, but communication is restricted to line of sight to these antenna and repeaters
