Engineering a Smarter Planet

Our Products and Technology

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.

Our Products and Technology

CSignum is the only wireless communications provider that enables transmission of data through the water-air boundary, water column, seabed and subsea structures using HydroFi technology.

Modernizing infrastructures

Digitizing data

Driving smart business decisions

Extending asset life

Through the water-air boundary

HydroFi technology uses modulated electromagnetic signals to transmit from subsea sensor to in-air receiver through a propagating medium boundary.

What it does

The HyFi Modem enables sensor to shore, real-time data transmission for deployments where cables cannot be used.

Its value over existing solutions

HydroFi Modems work in existing heterogeneous environments to overcome the limitations of cable, acoustic and optical technologies
