Ultra Electronics Ultra Electronics is a defence and aerospace company specialising in the design, manufacture and support of electronic and electromechanical systems, sub systems, products and services for aircraft, ships, submarines, armoured vehicles, surveillance and communication systems, airport and transport systems. Ultra Electronics Affiliated Company, Ultra Electronics Maritime Systems (UEMS), has developed a new method for communication where you communicate through Magnetic-induction (MI).

MI is a wireless technology that uses pure magnetic fields rather than radio’s electro-magnetic fields to communicate. MI has the ability to ”punch through” most natural and manmade barriers to provide effective tactical communication and command and control.

• MI can communicate wirelessly through soil, rock, salt water and urban structures while radio will not.
• Because MI does not use propagating electromagnetic waves, it is not readily jammed (unlike radio)
• Since it is range limited by design, it is inherently LPD and LPI.
• Since the system works through every media it can be used for communication in caves, tunnels or bunkers where wireless communication equipment usually not work.
• Typical application is voice / data communication, sensor control, alarm, weapon activation or navigation.
