The Importance of Standards• Standards provide people and organizations with a
basis for mutual understanding• Facilitate communication, measurement, commerce
and manufacturing• Standards form the basis for the introduction of new
technologies• Ensure that products, components and services by
different companies will be mutually compatible.
Play an important role in the economy• Easy business interaction • Comply with relevant laws and regulations• Speeds introduction of innovative products
• Everyday products and services• Lightbulbs into lamps• Common sizes for clothing• Trains on same size tracks

IMEA OneNet Standards CommitteeIMEA OneNet
© 2018 IMEA NMEA
• Embrace Ethernet for Marine Networking• Use standard IP network and addressing infrastructure• Specify the transport of NMEA network messages over IP
• Simple Installation, Configuration, and Use• Automatic discovery and setup of devices and services• Easy connection, configuration and management
• Interoperate with Established Marine Standards• Gateways to NMEA-2000, NMEA-0183, IEC 61162-450 standards• Co-exist with other IP protocols / services on the same cable
• DOES NOT REPLACE NMEA 2000
OneNet Goals
© 2019 NMEA
• Secure Device Communications• Prevent common protocol attack vectors• Significant security even on insecure networks
• Extendible, Scalable Architecture• Scales well to embrace future protocol standards • Inter-operate well with current and upcoming services
• Support high bandwidth applications • Video transport• Radar
• Final Phase – Comment resolution
OneNet Goals
© 2019 NMEA
• Much Greater Bandwidth & Device Count• NMEA 0183 –one device per cable, 5 - 40 kbits/sec, • NMEA 2000 – 52 devices per network, 250 Kbits/sec• OneNet – thousands per network, 100MB – 10GB/sec• OneNet is 40,000x faster than 2000
• More Power • NMEA 2000 provides up to 9 Watts per device• OneNet POE provides up to 25.5 Watts per device
