Abstract: In June 2018, ITS performed mobile clutter measurements in Salt Lake City, UT at 1.7 GHz. This measurement campaign was designed for path geometries with larger take-off angles by placing the transmitter in the hills of the nearby mountains. The resulting measurement dataset contains a large percentage of paths that would traditionally be considered line-of-sight (LOS), in that the terminals have an unobstructed view of each other. We present this LOS data and explore what a LOS path implies within a cluttered environment. We integrate high-resolution lidar data into our analysis showing that traditional assumptions of LOS links need further descriptors to clarify the frame of reference. Finally, we present how lidar data can be incorporated into modeling activities to support improved prediction methods and understanding of the expected clutter losses for such geometries.
