Multi wave propagation varies the signal strength which causes fading dips. This is known as Rayleigh fading which is frequency dependent. Frequency Hopping changes the frequency with time to eliminate frequency dependent Rayleigh fading. Frequency Hopping reduces the effects of interferences and gives a great support to cater the capacity upgrading as well.
