Abstract
A system includes a processor configured to detect a vehicle wireless signal at a first frequency-band. The processor is also configured to choose a second signal at a second frequency-band having a predefined relationship to a requested action. The processor is further configured to connect to the second signal and lower a signal data-transfer rate, responsive to the detection, and use the second signal to perform a time-of-flight based user-proximity detection, to determine if a user is within a vehicle proximity range associated with the requested action.
