802.11

802.11 is the specification for wireless ethernet which is what all of the 802.11a, 802.11b and 802.11g specifications are based on. 802.11 provides three PHY methods: FHSS, DSSS, and Infrared.

The FHSS method uses one of these for modulation (and FHSS for spectral spreading) (in order of rate improvement):

Frame headers are transmitted with 2GFSK at 1 Mb/s but the data portion's modulation (and rate) is variable.

The DSSS method uses one of these for modulation (and DSSS for spectral spreading) (in order of rate improvement):
