Cable-free communications

Unlock the potential of your underwater communications with our advanced acoustic and optical technologies. Our wireless performance revolutionises subsea data transmission. By eliminating the vulnerabilities of traditional underwater wiring, we provide a robust and innovative communication solution that adapts to your most challenging maritime research and operational needs.

Our acoustic and optical communication platforms are engineered to provide solutions for every underwater communication need. We understand that each project is unique, which is why our technologies can be precisely configured to your specific requirements across any water depth, bandwidth demand, budget constraint and power source configuration. Anything is possible, from optically streaming live HD video directly from underwater environments to collecting data acoustically from the ocean depths, all without the limitations of cables.

We deliver versatile deployment options that seamlessly integrate with your existing maritime infrastructure. Whether you’re operating research vessels, small survey boats, stationary buoys, unmanned surface craft, underwater vehicles or managing diving teams, our wireless data recovery and communication solutions ensure you stay connected in the most challenging aquatic environments.

Our digital Wideband signal technology provides unparalleled capabilities to track, communicate, and receive data wirelessly from underwater instruments, diving personnel, and underwater vehicles. The system’s robust design ensures reliable performance across any operating environment, from shallow coastal waters to the deepest ocean trenches.

Choose our wireless communication solutions and you dramatically reduce operational risks and costs. Traditional underwater cables are expensive, vulnerable to damage, and require frequent maintenance. Our acoustic and optical technology eliminates these challenges, lowering your maintenance and replacement expenses while simultaneously enhancing overall operational reliability and data integrity.
See below for an overview of our key communication products.

HPT Modem

Our HPT acoustic transceivers used to track underwater targets can also be used as efficient and reliable acoustic modems. If you need to harvest data from or communicate with Sonardyne-equipped sensors on the seafloor or from underwater vehicles, as long as your vessel is equipped with a Mini-Ranger 2 or Ranger 2 system, then you already have the tool to do the job. Versatility and operational efficiency comes as standard with our vessel-based technologies.
