Abstract: A network use optimization system may include a communication connection controller for being carried by a vehicle. The controller is configured to receive data signals from at least one data source, assign a data signal category to the data signals, and evaluate a current availability of each of a cellular data communications device and a radio frequency communications device. The controller is further configured to select one of the cellular data communications (CDC) device and the radio frequency communications (RFC) device for transmission of the data signals based on the current availability of each of the cellular data communications device and the radio frequency communications device and the category assigned to the data signals. The controller (1) outputs the selection to a person for confirmation and in response to a received confirmation, transmit the data signals using the selection or (2) automatically transmit the data signals using the selection.
