Car Connectivity based on Automotive Ethernet MATEnet interconnection system provides bandwidth, flexibility and reliability Page 12 Car Connectivity based on Automotive Ethernet MATEnet interconnection system provides bandwidth, flexibility and reliability TE AUTOMOTIVE /// White Paper | Car Connectivity based on Automotive Ethernet One application area are multiple microphone arrays in vehicles to enable different applications such as voice recognition, active noise cancellation, and in-car communications. In contrast to conventional expensive and heavy high fidelity cabling, the AD242x family of enhanced A2B transceivers works with low cost twisted-pair wire and connects devices in a daisy chain master-slave topography. Like PoDL, A2B can also supply power to other devices in the daisy chain. TE has begun to investigate the potential of MATEnet technology for A2B applications. — HDBASET — HDBASET is an emerging technology, providing up to 6Gbps full duplex data transmission through a 15 m link segment with up to 4 inline connectors at near zero latency. It includes various protocols like Audio / Video, Ethernet, Power and consumer applications like USB and HDMI. TE has an active part in the HDBASET Alliance, where automotive stakeholders collaborate in various technical committees to define appropriate automotive requirements and specifications. Native Networking Capabilities demon- strates the usability of unshielded twisted pair cabling, which can be compared to 100 / 1000 BASET1 applications. Addressing multiple challenges, HDBASET with its unprecedented bandwidth and suitability for existing UTP cabling systems like TE's MATEnet is a key enabler for future in-vehicle connectivity. 7 | SUMMARY AND OUTLOOK Digitization and connectivity are sweeping across the automotive industry because they are the enablers of every individual mobility mega trend: Integrating the car into the Internet of Everything, increas- ing vehicle efficiency, powertrain electrification and intelligent (predictive) hybrid operating strategies, establishing intelligent traffic solutions, and facilitating automated driving. Many new functions are based on networking individual functions/systems, on re-using sensor signals and on communicating with a backend (services) via the cloud and making vehicles part of a swarm intelligence. High-bandwidth, high-frequency data transmission will be a key enabler of connectivity. Automotive Ethernet offers the best cost-benefit ratio. MATEnet offers the robustness, reliability, affordability, fully automated handling, quality level, miniatur- ization, light-weighting, flexibility, and scalability to support car connectivity via Automotive Ethernet. MATEnet components are manufactured in TE plants which operate according to extremely high manu- facturing standards to ensure uncompromising product quality.
