The recommended mounting location is a traffic light or street light horizontal mast arm as close
to the center of the road or intersection as possible. In addition, the mast arm that is closest to
the traffic signal controller cabinet is used for installation.
Ethernet connectivity between each mounting location and the cabinet is required. Please
make sure that an Ethernet cable is routed accordingly. If Power Over Ethernet (PoE) is used to
power the device, Ethernet cable is the only cable required to be connected to StreetWAVE™
unit. This is the recommended method to power the RSU.
1.4.3 Optional Components
You may need to procure the following optional components if not already available at the
installation site:
1. Ethernet cable long enough to reach the RSU mounting location from the cabinet.
2. A CAT 6 weatherproof cable is required to connect the RSU to the traffic signal
controller cabinet.
3. An 802.3at compliant PoE injector is required inside the traffic signal controller to
interface between the traffic signal controller and the StreetWAVE™ RSU.
1.5 Various Parts and Functions
An ideal installation of the SW-1000 RSU will require the following parts/functions.
1. Mounting hardware: To enable mounting the RSU to the pole/mast. This consists of a
mounting bracket, mounting bolts and a metal strap
2. 802.3at compliant PoE switch and/or injector: To enable power and communications to
the RSU
3. DSRC antennas: N-type 5.9 GHz antennas for transmitting and receiving DSRC
messages
4. GNSS antenna: An L-1 band, GNSS (GPS, GLONASS or both) antenna for positioning
and timing
5. Self sealing electrical tape: To further ensure that there is no water seepage into the
antenna connectors
6. Lighting arrestor (Optional): Used to protect the RSU by preventing the rise in voltage
when struck by lightning.
