Introduction
The Savari S-50 is a purpose built On-Board Unit (OBU) for interoperability with a Transcore
LMU-TC (also known as ROVR in this document) and a Savari StreetWAVE™. The OBU
communicates with the LMU-TC and receives GPS breadcrumb information. The OBU stores
this data in persistent memory until it is able to upload it to the specific RSE. The
communication between the LMU-TC and the OBU is over aproprietary 2.4 GHz link whereas
the communication to the RSE is over a DSRC 5.9 GHz link. The S-50 OBU has been built as
a plug and play device without needing any user intervention. However, the S-50 OBU has
been equipped with a provisioning interface that can receive and load new versions of
software, new configurations and instructions to perform logging functions and download log
messages to an external device.
