Automotive Ethernet: Beyond 10 Gb/s Electrical PHYs call for interest

The following request for agenda time for a Automotive Ethernet: Beyond 10 Gb/s Electrical PHYs call for interest has been received from Steve Carlson. It will be discussed at the IEEE 802 LMSC March 2019 Plenary meeting in Vancouver, BC, Canada.

If you have any questions please get in touch with either or directly.

Ethernet data rates in automobiles are being driven by the push to fully-autonomous operation. 100BASE-T1 and 1000BASE-T1 are already in vehicles, and 2.5 Gb/s, 5 Gb/s and 10 Gb/s links (IEEE P802.3ch) are being designed in for model year 2023. With the move from domain-based architecture to zonal-based architecture, 10G+ links (typically redundant) between the electronic control units (ECU) will be required. Latest generation sensors (cameras, lidar, etc.) may transmit uncompressed data at rates greater than 10 Gb/s. "Black-box" data recorders also require 10G+ to handle the greater than 4 TB of data produced per day in autonomous cars. Test vehicles are under development using standard 25 Gb/s and 50Gb/s Ethernet, and will require an automotive Ethernet version for production. In order to meet the design cycles of the auto industry, the time to start this effort is now.

The call for interest will take place during the IEEE 802.3 Opening Plenary on the morning of Monday 11th March. A call for interest consensus building meeting has been scheduled to occur from 18:30 to 19:30 on the evening of Tuesday 12th March. The vote to determine if a Study Group will be formed will take place at the IEEE 802.3 Closing Plenary on the afternoon of Thursday 14th March.
