RTPGE is single-pair Ethernet( SEP) for data rates of 1 Gbit/s. The corresponding interface is 1000Base- T1. RTPGE was standardized by the IEEE working group 802.3bp and forms the physical layer in automotive Ethernet, which can be used as a platform. IP communication with the IP protocol according to IPv4, the User Datagram Protocol( UDP) and the Transmission Control Protocol( TCP) is based on this layer.
RTPGE is implemented as a point-to-point connection over less than three wire pairs. The range is 5 m, optionally up to 40 m. It has autonegotiation and operates on the physical layer with different encodings: 3B2T, 10B7T and 11B7T.
