Abstract
In a method for transmitting a desired parameter to a remote location, the desired parameter is first communicated to a base transmitter. Then, the base transmitter transmits a first radio signal therefrom having an unknown center frequency within a known frequency band. The first radio signal comprises information representative of the desired parameter. At a remote location, a remote receiver identifies the center frequency of the first radio signal and tunes the remote receiver to the center frequency thereof so as to facilitate reception of the first radio signal with the remote receiver. The information representative of the desired parameter may then be communicated to a desired destination.
