Vital Alert uses Very Low Frequency, magnetic induction transmission to create waves used to carry our proprietary digital signal through the earth and other man-made and natural barriers.

Vital Alert holds the exclusive rights to the Los Alamos National Laboratory (LANL) patent for digital transmission Through-the-Earth and has 4 additional TTE related patents.

Vital Alert secured the rights to the LANL patent in 2008 and has spent many years developing, testing, certifying and commercializing our TTE technology. This, together with our patent portfolio, makes Vital Alert the global leader in Through-The-Earth Communication and positioning technology.
