In the early 1800s it was discovered that every electrical current produces a magnetic field. If a coil is placed in that magnetic field it is possible to generate voltage. In the 1970s Auckland University researchers recognised the potential to harness this science. Decades of propriety research at the University of Auckland has optimised this system to allow transfer of usable amounts of electrical power wirelessly over large air gaps or through non-metallic media.


For more than 15 years, 3i Traffic has been operating in the field of wireless power, otherwise known as inductive power technology. 3i Traffic's inhouse research and development personnel have worked with the University of Auckland, resulting in proprietary innovations in the field.


3i Traffic is now regarded internationally as the "centre of excellence" for LED lighting through Inductive Power Transfer and Inductive Communications Transfer.
