StreetWAVE™ Features
This chapter explains the salient features of the StreetWAVE™ roadside equipment.
Following is the architecture diagram of StreetWAVE™. Each component is explained briefly in
the following sub-sections:
Figure 1: StreetWAVE Software Architecture Diagram
StreetWAVE™ features are explained briefly in the following sub-sections:
4.1
DSRC Radio Pair
Each StreetWAVE™ unit consists of two (2) integrated high power DSRC radios, which are
exposed as the following two interfaces:

Radio 1

Radio 2
StreetWAVE™ radio configuration is very flexible. Any or both radios can be configured on any
of the following channel modes:

Alternating Channel Access

Continuous Channel Access
The following applications can be configured to use any of the two interfaces (Radio1 or
Radio2):

Immediate Forward

Store and Repeat

IPv6-provider

DSRC Message Forward

TCD
Savari Inc., Confidential
Copyright © Savari, Inc, 2017
RSU2 User Guide

RTCM

NTP
However, radio configuration between the above-mentioned applications should be consistent.
You can operate multiple StreetWAVE™ units in a hub-and-spoke configuration in which the
hub unit originates a message. It broadcasts those messages on its configured DSRC interface
to OBUs as well as on Ethernet interface to the spoke StreetWAVE™ units in Savari ’s
proprietary format. The spoke StreetWAVE™ units receive them and broadcast them on their
DSRC interfaces, essentially working as DSRC repeaters. This configuration is useful at an
intersection where no specific location has line of sight to all approaches to the intersection.
The Hub unit does not have to be in the traffic controller cabinet. It can be one of the units on
the pole if it has Ethernet connectivity to the cabinet.
4.2
IPv4 and IPv6 Networking
Each StreetWAVE™ unit consists of one Ethernet interface (eth0). StreetWAVE™ provides
support for both IPv4 and IPv6 networking on all its interfaces (eth0, Radio 1, or Radio 2).
You can enable the following on all the three available interfaces:

IPv4 and IPv6 addresses

IPv6 Router Advertisements
StreetWAVE™ can forward both IPv4 and IPv6 packets between its interfaces (Ethernet and
DSRC) acting as a router. It also supports both IPv4 and IPv6 firewalls allowing the following:
4.3

Source and destination IPv4 or IPv6 addresses

Port-based rules
Immediate Forward
StreetWAVE™ Immediate Forward application supports the forwarding feature in addition to the
following features.
4.3.1 UDP Listener
StreetWAVE™ Immediate Forward application listens on configured UDP ports. If any message
is received on these ports in the format specified in USDOT RSE requirements, it will sign the
message using the 1609.2 protocol, if specified in the incoming message, and immediately
transmits on the configured DSRC interface with the PSID and channel specified in the
incoming message. Incoming messages could specify different priorities but it must specify the
same transmit mode (TxMode) and transmit channel (TxChannel). This feature is used when an
Savari Inc., Confidential
Copyright © Savari, Inc, 2017
RSU2 User Guide
intermediate device (TCID or a Battelle device) is sending periodic Immediate Forward
messages to a StreetWAVE™.
4.3.2 UDP Streaming
The StreetWAVE™ can be configured to receive data from other StreetWAVE™ and stream it
over DSRC. This allows the StreetWAVE™ to function as a repeater. In this setup, one
StreetWAVE™ is configured as the Hub unit and all other StreetWAVE™ that are connected to
it as Spoke units (that are not capable of independently transmitting Store and Repeat,
Immediate Forward etc. and are depending on the Hub to provide this data). The Hub transmits
the data over the air as well as to the Spoke unit typically over an Ethernet link. The Spoke unit,
upon reception of the Hub’s packet, decodes and applies rules that are present in the packet,
signs (if it is present in the packet) and forwards the packet over DSRC. The ability of the
StreetWAVE™ to function in this manner can be used for streaming the packet data (in Savari
proprietary format) from TMCs or back-end servers over the air. This arrangement could be
useful in scenarios where a single StreetWAVE™ may not provide ample coverage for the
geographic area of interest.
4.4
Store and Repeat
StreetWAVE™ supports transmission of Store and Repeat. The Store and Repeat application,
which runs on the StreetWAVE™ unit, transmits on the configured channel over the Radio 1
(default configuration) interface.
Store and Repeat are configured in a data store inside the StreetWAVE™. The data store
supports up to 100 Store and Repeat. The Store and Repeat are stored in the form of Active
message files. Each file contains the transmissions parameters and the actual data of the Store
and Repeat message. Each Store and Repeat message can be scheduled differently. The
active message files follow the USDOT RSE 4.1 Specification.
4.4.1 Active Store and Repeat Message Configuration
StreetWAVE™ supports the USDOT Active Message Configuration file format for configuring
active Store and Repeat messages.
US DOT Active Message Configuration file format
This format is defined in section US DOT RSU 4.1 requirements. Each Store and Repeat
active message should be defined in a separate file.

RSU2 User Guide
4.5
1609.3 IPv6 Provider
StreetWAVE™ supports WSAs as per the 1609.3 protocol. If enabled, StreetWAVE™ switches
channels on the configured interface between the following:

178 (control channel)

Configured service channel.
StreetWAVE™ runs IPv6 traffic on a service channel in the configured service channel interval.
Such IPv6 traffic is transparent to StreetWAVE™. It merely routes IPv6 traffic from/to DSRC
interface from the Ethernet interface.
StreetWAVE™ announces this service availability using WSAs including Service Info and WRA
elements. The Service Info element consists of PSID, channel information, and the service
channel. WRAs consist of router IPv6 prefix, gateway address, and DNS addresses so that
OBEs can configure their IPv6 addresses, default gateway, and DNS servers.
4.6
1609.2 Security
StreetWAVE™ supports 1609.2 Draft 9.3 security protocol.
It supports signed Immediate
Forward, and Store and Repeat messages and signed WSAs to announce IPv6 services. The
security feature can be individually enabled or disabled on Immediate Forward, Store and
Repeat, and IPv6 applications.
StreetWAVE™ ships with the following pre-generated certificates supplied by US DOT:

One root certificate

Five different message signing certificates

One WSA signing certificate
The following security profile is used for signing Immediate Forward, and Store and Repeat
messages:

Interface Logging
StreetWAVE™ supports logging all DSRC and IP messages transmitted and received in the
PCAP format to the persistent memory. All packet activity on all interfaces are captured and
logged in the PCAP format. The PCAP files can then be seen in Wireshark after file offload has
transferred the PCAP files to a back-office server. In addition, the system-status log messages
are logged to separate files. There is ~3GB of space set aside for this total logging.
A packet from an OBE can be received and logged potentially by all StreetWAVE™ units at an
intersection. This independent logging feature provides the ability to analyze which unit is
capable of hearing from which approach and from how far. However, it may require analysis of
logs from multiple StreetWAVE™ units to track a single vehicle. Such an analysis can be
performed using post-processing tools and is not the main function of StreetWAVE™. Hence,
this independent logging trade-off is chosen over the complexity of integrated logging.
4.8
DSRC Message Forward
StreetWAVE™ supports the DSRC Message Forward feature as outlined in USDOT RSU 4.1
specification. This application provides the capability to forward any DSRC message received
over the air to an external server over an ethernet link. The specification USDOT RSU 4.1 lists
certain filter criteria that must be met for the messages to be forwarded. The DSRC Message
Forward feature transparently forwards all messages if the filter criterion is successful. The
application does not terminate the packet with regards to security or content.

6.1
Log File Handling
The following are the log file handling functions of StreetWAVE™:
6.1.1 Interface Logs
This is a repository for all the packets received and transmitted from all interface radio 1, radio
2 and Ethernet.
The StreetWAVE™ starts deleting the oldest log files (Interface log and Systemlogs) once the
directory occupancy is 80% of the disk capacity.
6.1.2 Tx/Rx Packet Log File Name Format
TX/RX Packet log file names are in the following format:
___YYYY_MM_DD_HH_MM_SS.pcap, where
 is configured prefix
 is eth/dsrc0/dsrc1
 is out for outgoing packets and in for incoming packets
YYYY_MM_DD_HH_MM_SS is the timestamp in UTC when the file was opened.
For example:
root@StreetWAVE:/nojournal/pcaplogs# pwd
/nojournal/pcaplogs
root@StreetWAVE:/nojournal/pcaplogs# ls -l
-rw-r--r-- 1 root root
42808 Jul 20 00:47
StreetWAVE_eth_out_2011_07_20_00_47_26.pcap
-rw-r--r-- 1 root root
1594308 Jul 20 01:01
StreetWAVE_dsrc0_in_2011_07_20_00_47_55.pcap
root@StreetWAVE:/nojournal/pcaplogs#
6.1.3 Retrieving the PCAP Files
The .pcap files can be retrieved only from StreetWAVE™ to any external device through SCP.
NOTE: Please use manual log file transfer when the system is in “standby” mode.

RSU2 User Guide
6.1.4 Deleting the PCAP Files
Once pcap files are copied out of StreetWAVE™, it is advisable to delete them from
StreetWAVE™. This helps to conserve disk space on the StreetWAVE™ for further TX Packet
logging.
6.2
Network configuration
This is used to configure the IP addresses subnet and gateway for Ethernet and Radio1 and
Radio2
6.2.1 IP Address configuration
When a IP address (ipv4/ipv6) is configured / reconfigured for an interface, corresponding
gateway or gateway length should also be updated before committing the change.
6.3
Firewall configuration
Firewall configuration requires separate rules for IPv4 and IPv6. Configuration files are
separate for IPv4 and IPv6, but the format is same.
6.4
Immediate Forward
StreetWAVE™ Immediate Forward application requires the following two configurations:

The main configuration file containing the UDP configuration.

Incoming stream of messages as specified in US DOT RSE requirements
UDP streaming configuration is not needed if only one StreetWAVE™ unit is used at a given
intersection.
6.5
Store and Repeat
StreetWAVE™ Store and Repeat application requires the following two configurations:

The main Configuration file contains ActiveDB path and UDP configuration.
Savari Inc., Confidential

RSU2 User Guide

Store and Repeat active message configuration contains message scheduling
parameters and message contents. (As per USDOT Req 4.1)
6.6
Sample Safety Pilot Deployment configuration
StreetWAVE™ radio configuration is very flexible. Any or both radios can be configured on any
channel in channel switching or continuous mode. Any sub-system (Store and Repeat,
Immediate Forward, and IPv6 provider) can be configured to use any of the two interfaces.
However, channel mode, channel numbers, and DSRC radios between all sub-systems should
be consistent on a given StreetWAVE™ unit.
The following is the recommended configuration:

Store and Repeat and IPv6 run on Radio 1, channel-switching mode between control
channel 178 and any service channel (except 172/178). Store and Repeat transmits on
configured channel (182 default) in ActiveDB files and IPv6 runs on control channel.

Immediate Forward, Immediate Forward, applications run on service channel 182 on
Radio 2, which is in continuous channel mode.
One of the StreetWAVE™ units can be configured as a UDP streaming unit. This is called Hub
StreetWAVE™. Other StreetWAVE™ units can be configured as stream receivers and are
called spoke StreetWAVE™. However, if antennas are disconnected, these messages will not
reach OBEs. The Hub unit can also be one of the units on the pole. In either case, it requires
Ethernet connectivity to the cabinet. All spoke units also should have Ethernet connectivity to
the cabinet.
A sample safety pilot multi-unit deployment configuration is illustrated in Error! Reference
source not found. with salient configuration parameters. Only important parameters are shown
below for illustration. Those parameters that are not shown here should be left at defaults for
this configuration.
