  • ADDRESS gaps related to standardization for implementing Ethernet-based communication in automotive


What topics or issues does the OPEN Alliance SIG address?

In the early days, the main objective of the OPEN Alliance was to establish the industry standard for 100 Mbps Ethernet connectivity over a single pair, unshielded cable, i.e. BroadR-Reach® technology, and support its deployment with interoperability, compliance, channel specifications and tools. Today, the OPEN Alliance is focused on addressing a variety of automotive Ethernet technical challenges, including the deployment of 100BASE-T1, 1000BASE-T1, 1000BASE-RH, ECU/network test methodologies and the deployment of xMII interfaces.

What types of companies should partner with the OPEN Alliance SIG? Membership in the OPEN Alliance SIG is optimized for businesses in the automotive market. Members should be willing and able to help drive and support new interoperability requirements, third party testing, certification procedures and new data rate specification requirements.

What is the difference in becoming a Promoter versus an Adopter Member?

Promoter and Adopter members have the same rights in respect to participating in and contributing to the OPEN Alliance technical committees. Promoters also have the right and the duty to participate in Steering Committee meetings that deal with the organizational and strategic matters of the OPEN Alliance. Once members have contributed as an Adopter, they may apply to become a Promoter member. Existing Promoter members will then vote on the application. 

Who should sign the Adopter agreement from the applying company (president, VP, manager)?

Only one signature is required from applying companies and it is up to each organization to determine which officer in the company should sign the Adopter agreement.


How much does it cost to join the OPEN Alliance?

At this time, there are no fees associated with becoming a member in the OPEN Alliance SIG. However, as membership increases, as well as associated operating costs and other resources, future members may be required to pay a membership fee. Any changes to the membership policy for joining the OPEN Alliance SIG will be reviewed by the current Promoters and clearly communicated by the organization.
