A Prospect of Efficient radio-frequency based underwater Wireless Data Transfer

Under-water wireless communication link has been a topic of higher interest due to an increase in various underwater operations. Such operations demand higher bandwidth with a fast velocity. This paper presents the experimental and FEM based simulations to investigate the radio waves based wireless link because of its higher magnitude in bandwidth and speed as compared to acoustic and optical technologies. Conduction current method is employed to transmit and receive the data in a conductive medium (Saltwater) with varying propagation heights. The investigations reveal that at the shallow water (less than the length of dipole, below sea level) produce significant surface waves (Airwaves) resulting in unidentified data reception. The height below sea level, more than the dipole length has resulted in the least BER as such it may be called an authentic data reception model.
