NMEA OneNet

NMEA OneNet is a latest standard[1] for maritime data networking based on 802.3 Ethernet, and will complement existing onboard NMEA 2000 networks by allowing for high-capacity data transfers.[2]

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

The use of the X-Coded M12 connector allows for up to 10 Gigabit Ethernet,[3] but the full capabilities do not have to be utilized, and would also depend on the cabling that is installed.
