Narrative
This RF scenario emulates the wireless environment in Tampa, FL. around the Tampa Hillsborough Expressway Authority. In this scenario, we have four nodes, one is a Road-Side Unit (RSU) mounted at the traffic light in the Selmon Extension intersection. The other three nodes are Onboard Units (RBUs) installed at three vehicles, one is stationary and parked at the parking lot of the Tamps Expressway Authority, and the other two vehicles are mobile and follow each other on two roads.
Two simulation runs are considered where in the first run, the moving vehicles are traveling north and south in Meridian Ave. from the Selmon Extension intersection and turn around at Channelside Dr and back to the intersection.
The second run emulates the moving vehicles proceeding east and west in Twinggs St. from the intersection to N Florida Ave. and turn around to the Channelside Dr.
Both scenarios are obtained by Wireless InSite ray-tracer and configured as 4 reflections to find the paths between the transmitter and receivers. In addition to this RF scenario, a more complex scenario is also developed that considered one diffraction as well as the 4 reflections in the ray-tracing which provides a more realistic characterization of the wireless environment.
