Through the Earth Communication
Our through the earth (TTE) communication system uses Magneto Inductive (MI) technology with quasi-static AC magnetic fields as a wireless channel for signalling, communications, and navigation. The unique physical properties of the magneto inductive channel enable it to operate through almost any medium including ice, rock, soil, water, and concrete including subterraneous tunnels, caves or bunkers, as well as urban structures.
The MI channel produces no far field (RF) emissions; thereby, eliminating the possibility of detection outside of the operating area. This contributes to the MI channel's high resiliency to conventional electronic warfare countermeasures.
Ultra Electronics Maritime Systems, MI products provide communications solutions in areas where traditional wireless systems are unreliable and where direct cabling is problematic.
