1. A radio frequency signal transfer anomaly notification method comprising:
determining, at a first roadside unit, presence of an anomaly of wireless radio frequency signal transfer within a wireless communication range of the first roadside unit based on the first roadside unit receiving radio frequency communication of acceptable quality, if at all, from fewer than a quantity of mobile devices from which radio frequency communication is expected, wherein the wireless radio frequency signal transfer includes a communication signal reception, a satellite positioning system signal reception, or both;
determining, at the first roadside unit, a type of wireless radio frequency signal transfer of the anomaly; and
transmitting, from the first roadside unit to another entity, an anomaly indication indicative of the anomaly of wireless radio frequency signal transfer and the type of wireless radio frequency signal transfer of the anomaly.
