CSignum HydroFi Modems overcome the limitations of acoustic, optical and cabled subsea communications with new wireless solutions that automate and reliably transmit dynamic data as needed underwater and through the water-air boundary. As a result of innovative HydroFi technology, ocean industries can now optimize operations and connect “first mile” subsea data with last mile WiFi signals for an end-to-end digital infrastructure that enables them to respond quickly to change.
