Slow FHSS	Fast FHSS
In slow frequency hopping spread spectrum, multiple symbols are transmitted in one frequency hop.	In fast frequency hopping spread spectrum, multiple hops are required to transmit one symbol.
One or more symbols are transmitted over the same carrier frequency.	One symbol is transmitted over multiple carriers in different hops.
Symbol rate is equal to chip rate.	Hop rate is higher than symbol rate.
Hop rate is lower than symbol rate.	Hop rate is higher than symbol rate.
A jammer can detect this signal if carrier frequency in one hop is known.	A jammer can’t detect this signal because one symbol is transmitted using more than one carrier frequencies.
