The propagation characteristics of Electro Magnetic (EM) waves in the soil and also the significant differences between the propagation in the air prevent us from obtaining one direct feature for Wireless Underground Channel. In fact, the underground environment consists of soil, rock and water instead of the air. The challenging reasons of these environments to propagate the wireless signal via the Electro Magnetic (EM) 1 waveguides are considered as: the high path loss, channel dynamic conditions and the high size of antenna. In this study, the details of Bit Error Rate (BER)2 for 2PSK modulations, path loss and the bandwidth of the Magnetic Induction (MI) 3Systems in the underground environment via one small induction coil were evaluated .At the end of this study, a general framework is obtained about the wireless underground communications and wireless underground sensor network. It is concluded that using the proposed framework, the transmission range in MI waves system would be raised and the path loss in that system would be declined severely.
