In comparing wireless technologies subsea radio waves prefer shallow water and can cross the air/water/seabed boundaries easily.[10] Subsea radio communication is generally limited to under 50 meters (160 feet) through seawater.[12] Subsea radio waves are unaffected by turbidity, salinity and pressure gradients[12] and also has a notable difference between acoustic and optical technologies, in that radio waves can pass through the water-air and water-seabed boundaries easily.[12] Subsea acoustics are efficient at long-range of up to 20 kilometers (12 miles)[10] and have relatively low power consumption for their range.[13] Acoustic communication systems generally perform poorly in shallow water and complex environments and has a limited bandwidth.[10] Subsea optical has an ultra-high bandwidth and a very short range.[10] Subsea optical communication does not cross the water/air boundary and is susceptible to turbidity.[10] Most underwater sensor networks choose acoustics as the medium for wireless transmission.[14] Electromagnetic waves offer great merits for transmission in special underwater environments.[14] Applications for subsea wireless sensor technologies can include subsea wireless sensor networks (WSN) for production monitoring,[13] or oil and gas pipeline monitoring within a wireless linear sensor network (LSN).[15]
