FrequencyHoppingSpreadSpectrum is a technique for utilizing spectrum in a thoughtful way. FHSS chooses a set of small channels (say 1MHz) within a band and then periodically (and predictably) hops between them (perhaps every 224 microseconds?). ["802.11"] requires the implementation of this, but ["802.11b"] abandons it in favor of ["802.11"].
