802.11 FHSS

Frequency-hopping spread spectrum in a 2.4 GHz band

Carrier sends on one frequency for short duration then hops to another frequency for same duration, hops again to another for same amount of time and so on

Spreading adds security since only sender and receiver agree on sequence of allocated bands

Contention is handled by MAC sub layer since all stations use the same sub bands

Pseudorandom number generator chooses the hopping sequence

Data rate is of 1 or 2 Mbps
