From The Free On-line Dictionary of Computing (27 SEP 03) [foldoc]:

  wi-fi
       
           Either of two different incompatible radio-based
          {LAN} {protocols}, namely {802.11b} (which speaks {DSSS} at
          2.4GHz) and {802.11a} (which speaks {OFDM} at 5GHz).
       
          The term was invented by the marketing departments of wi-fi
          equipment manufacturers.  It is, notionally, short for
          "wireless fidelity", on the analogy of hi-fi for "high
          fidelity" audio.
