WNC-M25MSO4
Silver Edition OEM Configuration Modem
Subnero’s silver edition underwater smart modem is the workhorse communication node to be used in the general commercial deployments. This modem also provides options for customization and extension at many levels, allowing network protocols as well as physical layer algorithms to be implemented and tested easily.
Key Features
- Up to 15 kbps data rate*.
- Up to 5 km communication range (horizontal & vertical) in tropical waters.
- Ranging functionality with 0.1 m precision.
- Doppler resilience of ±4 knots or better.
- Support for coherent and incoherent communication schemes.
- Support for arbitrary signal transmission as well as recording (passband, baseband).
- Support for user defined communication schemes using UnetStack.
* Depending on channel conditions and reliability requirements.
OEM Configuration
The OEM configuration (OC) is tailored to facilitate seamless integration and adaptability, making it a top pick for incorporation into larger platforms, such as AUVs, ROVs, and sensors. Additionally, for free flooded platforms, it comes equipped with a pressure hull option.
