The system also includes a controller that includes a selector function. The dual-mode communication unit transmits a first copy of bearer data to the first transceiver utilizing the first air interface. The dual-mode communication unit transmits a second copy of the bearer data to the second transceiver utilizing the second air interface. The first transceiver and the second transceiver sending the copy of the bearer data to the controller. The first transceiver and the second transceiver also send a quality metric to the controller.
