Although, attenuation in Electromagnetic (EM) wave propagation underwater is high at high frequencies, the theory predicts that propagation is possible at some useful distance in the lower Industrial, Scientific and Medical (ISM) band. The aim of this paper is to study the feasibility of using radio transceivers underwater for developing a Wireless Sensor Network (WSN) that could be used in various applications. Experiments with low cost wireless sensor transceivers operating at a frequency of 2.4GHz ISM band were carried out and data was successfully wirelessly collected underwater. Wireless Sensor Networks is proposed for increasing communication range. Furthermore, antennas experiments shown that monopole outperformed and will be selected for further stage in underwater communication systems. (6 pages)
