7.4.2 C-ITS Communication Mediums
The C-ITS platform would use various communication mediums depending on the C-ITS application to be delivered. For example, vehicle-to-vehicle and/or vehicle-to-infrastructure safety applications require low latency, highly reliable and free communication mediums. The primary communication means of these applications would be Dedicated Short Range Communications (DSRC) via the 5.9 GHz radio band. This band is critical for the objectives of C-ITS to be achieved. It is recognised that C-ITS will need to address the interaction and interfacing between 5.9 GHz and other rapidly evolving communication mediums such as cellular networks and private microwave and fibre networks.
