1 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.

3 Savari S50 Features
This chapter explains the salient features of the Savari S-50 (alternatively known as OBU in
this document).
3.1 Radio
Each S-50 unit consists of two radios:
• A high-powered 5.9 GHz DSRC radio
• A 2.4 GHz radio that operates on a proprietary protocol
Both radios feature an internal antenna.
3.2 IPv4 and IPv6 Networking
Each S-50 unit consists of one Ethernet interface (eth0) and one wireless interface (ath0).
The S-50 provides support for IPv4 on its Ethernet interface and IPv6 networking on its DSRC
interface. The latter functionality is seamless to the user and does not require any
configuration. The Ethernet interface is accessed using the mini USB connector on the S-50. A
corresponding USB to Ethernet adaptor will be required. The default IPv4 address is
192.168.40.40.
3.3 Transcore Application
The specific application has two parts: A downstream communication with the LMU-TC and an
upstream communication to the Savari RSE.
3.3.1 Transcore Application
The Savari S-50 is a small form factor purpose-built DSRC OBU that is capable of 2.4G
wireless communications with a Transcore LMU-TC and receiveing GPS breadcrumb data in a
proprietary format. The S-50 resides in the taxi and is connected to vehicle power using a 2
pin custom cable. See Appendix A for details on the power connectivity.
The RSE transmits a DSRC Wave Service Advertisement (WSA) with a specific Provider
Service Context (PSC) String (defaulted to ‘tsf0’). The WSA is transmitted every 100 ms from
the RSE. The WSA message contains many parameters and instructions that are interpreted
