Its value over existing solutions
HydroFi Modems work in existing heterogeneous environments to overcome the limitations of cable, acoustic and optical technologies and provide reliable data transmissions across the water-air boundary, adding flexibility for deploying and moving equipment easily between different monitoring points.
Optical solutions are subject to marine growth on the units and don’t work well in tidal seawater or water that is turbid or choppy, where light is ambient or where line-of-sight is limited or non-existent.
Acoustic signals cannot cross the water-air boundary and have difficulty transmitting signals in shallow water, degrade in turbid or choppy water, and may affect marine life.
Marine cables are under constant threat of water ingress, often fail due to dynamic bending stresses from wave motion particularly in the splash-zone are engineered at considerable cost.
