Wireless sensor network for underwater communication

Although attenuation in electromagnetic 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 speaker has studied the feasibility of using radio transceivers underwater for developing a wireless sensor network that could be used in various applications. Experiments with low-cost wireless sensor transceivers operating at a frequency of 2.4 GHz in the ISM band were carried out, and data was successfully wirelessly collected underwater. A wireless sensor networks is proposed for increasing the communication range. Furthermore, antenna experiments showed that monopole antennas outperformed other types, and will be selected for a further stage in developing the underwater communication systems.
