Navigating the Road to Connectivity: Use Cases and Design Considerations for V2X Networks Using Millimeter-Wave 5G Beam-Steering Antennas

Connected and autonomous vehicles (CAVs) rely heavily on a suite of perception sensors such as cameras and LIDAR for accurate and robust on-road decision making. However, these sensors have a limitation of line-of-sight (LOS), which can significantly restrict their effectiveness. To overcome this limitation, vehicle-to-everything (V2X) networks are being developed to wirelessly receive non-line-of-sight (nLOS) data from surrounding sources such as road-side units (RSUs). By leveraging nLOS data, V2X networks can significantly enhance the situational awareness of CAVs, improving traffic efficiency and road safety. In this paper, we present selected use-cases of V2X networks such as vehicle-to-vehicle (V2V) communication, vehicle platooning and cooperative perception using a beam-steering antenna that offers a wide bandwidth and fast beam-steering.
