Abstract
The most important difference between the wireless underground sensor networks (WUSNs) andthe wireless ground sensor networksis the propagation environment of the signal .In fact, the underground environments consist 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) 2waves are considered as: the high path loss, channel dynamic conditions and the high size of antenna. At the present study, the details of Bit Error Rate (BER) 3 for 2PSK modulation, path loss and the bandwidth of the Magnetic Induction (MI) 4Systems and Electro Magnetic (EM) Waveguide in the underground environment areevaluated. Meanwhile, a new method isintroduced via MI waveguide that provided the constant conditions of channel by the small inductive coils. At the end of this study,itisfounded that the transmission range in MI waveguide system would be raised and the path loss in that system would be declined severely.
