OPEN ALLIANCE SIG: KEY GOALS & OBJECTIVES
 ESTABLISH 100Mbps BroadR-Reach® physical layer
specification as an open industry and de facto standard
 ENCOURAGE and support the development of a high-speed
physical layer solution in a standards organization
 EXAMINE interoperability requirements and identify
independent parties to conduct interoperability testing
 ADDRESS gaps related to standardization for implementing
Ethernet based communication in automotive
