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 roadside 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 beamsteering antenna that offers a wide bandwidth and fast beamsteering.
