Claim:
A method comprising: at a wireless radio frequency receiver: in a learning mode of operation: scanning each of a plurality of carrier frequencies as are included in each of a plurality of different carrier frequency groupings to identify which one or more of the carrier frequency groupings contain a carrier frequency being used by a wireless radio frequency transmitter to thereby provide at least one identified grouping; in a normal mode of operation: using the at least one identified grouping, but not groupings that were not identified as an identified grouping during the learning mode of operation, to scan each of the plurality of carrier frequencies as are included in each of the at least one identified grouping to thereby receive a message transmitted by the wireless radio frequency transmitter; receiving the message using a first carrier frequency that comprises one of the plurality of carrier frequencies; receiving the message also using a second carrier frequency that comprises one of the plurality of carrier frequencies that is different than the first carrier frequency.
