aks,
fast fading, rayleigh fading… google it. It is the cancellation of phases of a signal that travelled through multiple paths.
ALU,
good geographic skills !
FH was not activated everywhere : in remote area, the operator used NH.
FH is well known for helping with frequency planning & interference, but less known for its coverage enhancement properties. So in remote areas, I do’nt blame anyone for not activating FH.
On top of that, FH on a cell with 2 TRX sounds useless:
either BBH over 2 frequencies
or SFH on 1 TRX. But then the BCCH TRX doesn’t get the frequency diversity.
what do you think ?
