Abstract

This paper introduces the concept of a magnetic field area network (MFAN), which uses low-frequency magnetic-field signals by loop antennas. It has two layers, data link layer and physical layer. The physical properties of magnetic field signals enable these systems to operate through soil, rock, water and medium boundary as well as air although magnetic field strength falls off rapidly. Additionally, Loop antennas make it possible to implement low-frequency communication systems. We have designed physical layer functions and a system including ARM7TDMI, FPGA, and several peripheral devices.
