It is not correct to refer to (DSRC) On Board Units (OBUs) as "transmitters". There is no transmitter inside those devices, as they reflect the incoming 5.8 GHz carrier, and just modulate this carrier wave, to transfer information back to the road side.

Without any carrier wave from the road side, they can in practice not transmit any information whatsoever.
