NMEA OneNet

NMEA OneNet is a future 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.

OneNet is to be announced "by 2014."
