CSignum - Model HydroFi -Wireless Datalogger
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 subsea, and bi-directionally 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.
- Crosses the water-air boundary
- Works reliably in turbid, choppy, low light and biofouled environments
- Automates data transmissions
- Requires less maintenance
- Works through concrete and beneath the seabed
- Requires less power, extends battery life for greater efficiency
- Multiple deployment scenarios
- Greener solution enhances safety, protects ocean life, reduces emissions
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.
Ideal for splash zone and shallow waters, where adverse conditions exist, HydroFi (HyFi) Modems are designed to pair with underwater sensing systems and wirelessly transmit data from the sensing system to a receiver above the waterline.
The HyFi Modem is compatible with multiple sensors using industry standard communication protocols and electrical interfaces. The subsea sensing system is programmed to wake up the HyFi Modem to pass data packets to a topside receiver which connects to a cellular or SATCOM network to deliver data to the operator’s desktop. The HyFi Modem enables sensor-to-shore, real-time data transmission for deployments where cables cannot be used.
