Any Nokia BTS Engineer to explain? thanks… 21st December 2005 at 15:58 #43330 TagGuest Hi, AFE=Antenna filter extendsion WBC is just a stand alone combiner for combining 2TRXs.

AFE is for Nokia talk family, Whereas WBC is for ultrasite. 22nd December 2005 at 02:25 #43331 YasiGuest Thanks Tag, btw do you require a Duplexer for WBC??? 22nd December 2005 at 05:12 #43332 TagGuest Yes, Duplexers is needed for both the equipment as it consists of the TX and RX path. 30th December 2005 at 00:13 #43333 MaciGuest Hi, Is there a restriction on the type of Nokia Combiner (i.e. RTC, AFE, WBC) for BB or RF hopping? Thanks. 3rd January 2006 at 16:46 #43334 vittyGuest AFE has a filtering role, WBC (ie WCGA) is purely a combiner V. 4th January 2006 at 13:50 #43335 PatrickGuest 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 3db Use TX on DVxx= Pmax use WBC + DVxx= You lose 3db Author Posts Viewing 7 posts - 1 through 7 (of 7 total) The forum ‘Telecom Design’ is closed to new topics and replies.
