This paper examines the performance of magnetic induction communication systems for body area networks. First a theoretical study, examination and investigation of the properties and capabilities of near field magnetic induction communications as an emerging form of short range telecommunications access is given. From both a theoretical and hardware tests, results are correlated showing strong agreement between theory and hardware implementation. It is shown that power decay follows an inverse law of distance to power 6 and that certain structures in the communication terrain can affect the magnetic flux created by the transmitter from reaching the receiver thus limiting the range of communications. A body area network of the devices is shown in which a centralised hub aggregates data from the nodes before accessing a wide area network of choice
