Technical Paper Abstract
Use of the Wireless medium in more deterministic applications, more generally known as Motion applications, requires some ability to be time sensitive to below 250 microseconds. This paper examines the tools available to enable time synchronization and how they relate to CIP Motion. Investigations into adding Time synchronization to the hardware infrastructure found the latency on 5G is relatively closed loop motion control, which would not require infrastructure time synchronization, only peer to peer.
Using Precision time protocol in C2C (Controller to Controller), D2D (Device to Device), D2C (Device to Controller) and C2D (Controller to Device) theoretical applications, D2C and C2D applications where deemed the most feasible. In the applications, Closed Loop Motion control was the dominant solution for time synchronization. This paper’s findings suggest C2D and D2D (sidelink) 5G applications are an easy to use and robust toolkit for wireless CIP Motion.
