Abstract
A remote keyless entry system includes a portable communication device for communicating with an electronic control module of a transportation vehicle. The transmitter has at least two selectable communication channels for broadcasting communications signals to the transportation vehicle. A vehicle based electronic control module communicates with the portable communication device. The electronic control module includes a receiver that includes at least two selectable communication channels for receiving RF signals from the portable communication device. A controller selectively energizes the receiver for measuring a RSSI voltage level of each selectable communication channel of the receiver over respective predetermined time periods. The controller determines which of the at least two selectable communication channels includes a lowest noise level based on the measured RSSI voltage level. A channel status update signal is broadcast from the electronic control module to the portable communication device identifying the selected communication channel having the lowest noise level.
