What is Frequency-hopping Spread Spectrum Technology – (FHSS)?

FHSS uses a narrowband carrier which hops through a predefined sequence of several frequencies at a specific rate. This avoids problems with fixed channel narrowband noise and simple jamming. Both transmitter and receiver must have their hopping sequences synchronized to create the effect of a single “logical channel”. To unsynchronized receivers an FHSS transmission appears to be short-duration impulse noise. 802.11 may use FHSS or DSSS.
