Vehicle-to-everything (V2X), also known as cellular-V2X (C-V2X) is a technology, with a clear evolution path to 5G that defines two transmission modes that, together, enable a broad range of use cases:
Direct C-V2X, which includes vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I) and vehicle-to-pedestrian (V2P) providing enhanced communication range.
Network communications (V2N), vehicle to network, in traditional mobile broadband licensed spectrum leveraging existing cellular network infrastructure.
