Physical Object: Pathway Communications Unit

PCU Communications

Overview

'PCU Communications' provides basic radio communications between pathway infrastructure and nearby mobile devices. Communications with adjacent field equipment (including other PCUs) and back office centers that monitor and control the PCU are also supported. It supports the lower layers of the OSI stack, specifically the TransNet and SubNet layers of the ARC-IT communications model. Message relay capabilities are also included to improve radio communications range, reliability, and performance.
