Communication with Gravitational Waves?

Generation and detection of gravitational waves at microwave frequencies by means of a superconducting two-body system
In engineering, it could open up the possibility of intercontinental communications by means of microwave-frequency gravitational waves directly through the interior of the Earth, which is transparent to such waves. This would eliminate the need of communications satellites, and would allow an economical means of communication with people deep underground or underwater in submarines in the oceans. Such a new direction of gravitational-wave engineering could aptly be called “gravity radio”
