FHSS
(Frequency Hopping Spread Spectrum)
HPMX-5001 \ HPMX-5002 \ HPMX-3003 \ HPLL-8001
form a complete radio solution for an 802.11 compliant FHSS system.
DSSS
(Direct Sequence Spread Spectrum)
Product fit for 802.11 compliant DSSS applications is the same as for the 2 GHz ISM band handheld applications.
