Single Pair Ethernet for the Industrial Internet of Things: Accurate Line Measurements

In this work accurate measurement setups have been developed in order to determine the per-unit-length parameters of Single Pair Ethernet (SPE) transmission lines in the frequency range 0 Hz − 1.0 GHz. In particular, the frequency dependence of all per-unit-length parameters will be derived, which goes far beyond the information in conventional data sheets. Based on these measurement results, accurate simulations in the fields of Automotive Ethernet, Internet of Things (IOT) and Industrial Internet of Things (IIOT) can be performed in future.
