NMEA OneNet is a latest standard for maritime data networking based on 802.3 Ethernet, and will complement existing onboard NMEA 2000 networks by allowing for high-capacity data transfers.
Current maritime data networks have bandwidth capacities of less than 1Mbit/s. Building on Ethernet, OneNet allows for capacity in the hundreds or thousands of megabits per second. This extra bandwidth is needed for transferring unprocessed sensor data from sonar/radars, as well as video feeds from for example an engine room.
The primary features and goals of OneNet are as follows:
- NMEA 2000 data transfer over IPv6 in a standard format
- High-bandwidth applications such as radar, video and more that are not possible via NMEA 2000
- Support Ethernet and TCP/IP at 1 gigabit and faster speeds
- Utilize standardized connectors (RJ-45 and X-Coded M12) depending on installation
- Robust, industry-standard cybersecurity requirements
- NMEA 2000 gateway compatibility
- Mandatory device & application certification by the manufacturer, then verified by NMEA
