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.
