Time synchronization

With DSRC radio, the POTI service provides a configured position for testing without the GNSS signal. You can upload the POTI configuration file through v2xcast_manager.

Due to the CV2X PC5 radio being based on 3GPP RF requirements which need highly accurate timing synchronization, the CV2X devices cannot send and receive messages without any GNSS signal. In our experience, most of our customers including ourselves use GNSS repeaters for indoor testing.
