Fast Underwater
Wireless Communication


LUMA™ is a line of optical modems that are compact, power efficient, and operate from the splash zones down to 6’000 meter depth with a communication speed of up to 10 Mbit/s and the range of up to 50 meters.

Plug & Play

LUMA is designed with flexibility in mind. In its base configuration, it is a transparent link between your legacy systems, making it very easy to integrate. Plug&Play is not just marketing language when it comes to LUMA.

Fast. Faster…

LUMA modems are lightning fast. They can send data at up to 10 Mbit/s bandwidth enabling truly HD-quality video transfer wirelessly through water in real time.

LUMA penetrates air to water barrier with no effort, making it a great alternative to cables in extremely unforgiving splash zone conditions. 

From Splash Zones...

...To 6’000M Depth

LUMA offers unparalleled connectivity and can be a vital agent for real-time monitoring of structures in digital twin systems.

Unmatched Power Efficiency

Our most advanced LUMA modem will consume 1500 times less energy than a fastest acoustic modem on the market per bit of data.


With the small size, low power consumption and high data rates, LUMA opens up new connectivity possibilities underwater in many industries where submerged assets need to be monitored or inspected in real time.

LUMA enables wireless HD video connection for the resident autonomous underwater vehicles (AUVs) so that the pilots could take control over their AUVs remotely near the assets.
