Abstract
A radio frequency communication system includes a transmitter that selects a frequency channel from among multiple frequency channels available to the transmitter and to a receiver, listens to ensure that a selected channel is unused before transmitting, and sends a preamble longer in time than a receiver scan time during which the receiver is operable to scan all frequency channels available to transmitter and receiver for the preamble. The receiver scans through the available frequency channels for a preamble, finds the preamble on a channel, and locks on to the channel on which the preamble was found.
