I wish to find out what is the difference between AFE and WBC??
Any Nokia BTS Engineer to explain?
thanks…Hi,
AFE=Antenna filter extendsion
WBC is just a stand alone combiner for combining 2TRXs.
AFE is a unit that consists on Combiners,Duplexers,Splitter,LNA.
AFE is for Nokia talk family,
Whereas WBC is for ultrasite.
Thanks Tag, btw do you require a Duplexer for WBC???
Yes,
Duplexers is needed for both the equipment as it consists of the TX and RX path.
Hi,
Is there a restriction on the type of Nokia Combiner (i.e. RTC, AFE, WBC) for BB or RF hopping?
Thanks.AFE has a filtering role, WBC (ie WCGA) is purely a combiner
V.
WBC + DVxx = AFE
you have only 2Tx on copler DVxx, if you want more 2 TRX you must insert WBC.
For the puissance:
use TX on AFE= Pmax
use TX1 and TX2= you lose 3dbUse TX on DVxx= Pmax
use WBC + DVxx= You lose 3db
