Enabling Technologies for Range Enhancement of MI Based Wireless Non-Conventional Media Communication

The most efficient way of establishing communication through radio waves are no longer suitable in Non-Conventional (No-Co) media viz. underwater & underground due to dynamic channel conditions. To overcome the associated problem, researches have proven Magnetic Induction (MI) communication method to be more suitable in these media. As, the principle operation of this method is at low band frequency, thus providing constant channel conditions for the magnetic fields in these media. MI communication is a very promising & emerging technology, but it suffers from a major drawback of short-range communication of upto few meters only. Recent researches in the field have shown ways for increasing the range of MI communication through coil parameters, structure, material, configuration, etc. This paper provides a categorized brief summary on accounts and ways of increasing the range of MI communication in No-Co media.
