Underwater communications to

connect networks up here

To digital things down here

wirelessly, without cables

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

Say hello to

The first and only platform to carry data with low frequency electromagnetic fields, nature’s perfect through-the-surface energy for cable-free data transport between more devices in more places than ever before.

Data Rate

We sustain 200 bps through water, the surface, and the air, optimizing power consumption and battery life with enough capacity for virtually every traditional type of sensor mission.

Signal Range

Regardless of water quality – aerated, turbid, etc. – RadiEM handles distances between modems of 30 meters to connect your data below the surface to computing power above the surface.

Battery Life

While battery life is highly variable, a typical 15 minute transmission interval yields 3 months without recharge or replacement.

One Minute Intro to

As our video shows, the key issue that our underwater communications technology solves is the difficulty getting sufficient data from below water of all kinds to the networks above water, onshore. As an American-owned, Scottish-based business, the investment in R&D has already been substantial. It’s why we’re able to support offshore industries, as well as the wider water industry worldwide.

We believe that rather than replacing other modems that use acoustic or optical modems, our underwater communications technology complements those solutions, overcoming the challenges those data transmission types have, because of how resilient, silent and invisible electromagnetic fields are, even under and through water, as well as achieving seamless data transmission across the air/water barrier.

FROM THE DESK OF OUR CEO…

“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.”
