Underwater communications to

connect networks up here

To digital things down here

resilient

EM fields are not only underwater communications that travel through more environments than sound, light, or radio, they also sustain more integrity on their journey. That’s why EM fields uniquely pass through the surface of water while sound and light scatter.

silent

Until now, acoustics have been the global foundation of underwater data communications . As our sensitivity to marine life grows however, silence becomes a more beautiful option every day. And of course for security, silence means safer.

invisible

When data speeds are critical, and the water quality is right, optical systems deliver. But, if marine life is sensitive, or security is in play, only totally invisible EM delivers performance and stealth.

We use electromagnetic fields to connect data networks above the water to digital things in the water

Resilient Cable-Free Communications

Breaking Through the Barriers –  CSignum’s EM-1 solution uses patented electro-magnetic field signaling (EMFS) for wireless communication, uniquely capable of transmitting data from the seabed to the shore, from a ship’s hull and propulsion systems to the deck, and from riverbed to riverbank. This technology can transfer data without reflection at the water-to-air interface, a common issue with acoustic systems.  

CSignum’s EM-1 supports bidirectional sensor data transfers at distances up to 50m, extendable to 200m with an external antenna enabling the successful deployment and operation of Internet of Underwater Things (IoUT) monitoring devices. The CSignum electromagnetic field based communications method can also be used to communicate underground and pass data through rock, concrete and soil.

Technology is changing faster than ever to adapt to the world’s challenges. CSignum transmits automated, digitized data dynamically when and where it needs to be. Armed with dynamic readings, our customers can make data-driven decisions for any situation they encounter — whether that means structural integrity of an offshore platform, preventing harmful algae blooms, improving ocean observing or optimizing the health and sustainability of fish farming.
