OEM Development Platform
UnetCube
An embedded platform for building your own underwater modems and hybrid communication nodes.
Build Your Own Underwater Modem
UnetCube is a compact embedded computing platform running UnetStack OEM Edition natively on a single board computer. It allows developers to connect their own analog electronics while relying on UnetStack for signal processing and communication protocols.
This dramatically reduces development time by eliminating the need to rewrite core PHY, MAC, or networking layers, giving you a powerful software-defined foundation.
Key Capabilities
Focus on your hardware differentiation, let UnetCube handle the stack.
Native Execution
Runs UnetStack on embedded SBCs with full agent support.
Custom Integration
Supports custom ADC/DAC & analog front-end integration and custom PHY layers.
Build your Modem
Seamless transition: Simulate -> HIL -> Your Modem.
Hardware Control
Complete control over hardware design and optimal utilization of resources.
Use Cases
UnetCube provides a flexible embedded platform for desktop HIL simulations, building custom modems, or as a network controller for your subsea network.
UnetCube for HIL Simulation
Use UnetCube to run hardware-in-the-loop simulations before procuring modems, reducing upfront costs while allowing you to scale effortlessly by transferring the same codebase to actual modems for sea deployment. Developers can run signal processing, MAC, or networking algorithms as if the devices were operating underwater, enabling controlled and repeatable testing long before field trials.
Build Your Own Modem
UnetCube lets you rely on UnetStack to handle signal processing, networking protocols, and other software functions, allowing you to focus fully on designing the hardware portions of your modem for any supported frequency band. Its open-source interface protocol enables you to build your own modem with minimal third-party support—and even replace parts of the stack—thanks to UnetStack’s open, extensible architecture.
UnetCube as a Network Controller
UnetCube can act as a network controller for mixed fleets of legacy or Subnero modems, enabling you to build and execute custom network protocols to control subsea assets. Similar to a core router in terrestrial networks, it provides a flexible platform for orchestrating communication across distributed underwater systems.
