This experimental scenario involves communication between a fixed tower and a ground mobile node (e.g., a shuttle, car, or rover), as illustrated in the figure. The mobility pattern of the vehicle may or may not be known to the experimenter in prior. Moreover, a vehicle driver may (e.g., a passenger car controlled by AERPAW personnel) or may not (e.g., shuttles, rovers) be needed.
Example experiments in this scenario include vehicle-to-everything (V2X) communications and side-link communications. Experiments can involve two or more SDRs, or SDRs and other equipment (e.g. RF sensors, base stations, IoT gateways/sensors). Similar to UAVs, the UGVs (rovers) will have Pixhawk controllers on them, and hence, experimenters will have the possibility to integrate autonomous trajectory control for experiments that involve UGVs. This makes it possible for a wide range of interesting experiments, where one or more UGVs can individually (or in cooperation) adjust their trajectories based on real-time signal observations.
