try to chick the VSWR and the IDB3rd September 2013 at 19:51 #63144dickson richyGuesthow to solve rx path imbalance
4th September 2013 at 17:57 #63145pixGuesthi,
check your antenna system, there is one of the 2 feeders for that sector which is not transmitting signal to your BTS properly.
So check, frombottom to top:
0/ vswr on each cable
1/ bts internal cabling tx and rx
2/ jumpers from bts
3/ feeders
4/ couplers / diplexers/triplexers
5/ tma
6/ jumpers to antennathe idea is to find an inversion somewhere.
you can also check sdcch/tch allocation success rate for each trx, see if some trx are poor. In such case, check other sectors too. if other TRX are poor too, then you can assume there is a cross jumpers issue.
regards
9th January 2014 at 17:17 #63146ngocvectorGuestI think you should re-check the steps as bellow :
-Jumper & feeder cable & connector
-VSWR
-involvement equipment
* If everything is ok, you should supervise antenna to show parameter get simple and receive power level how much dB and associate with BSC to check some power control parameter. cause of it has some issue but BTS can not check.
Have a success..!13th March 2015 at 22:33 #63147ishmaelGuestRx path imbalance in 6101 cabinet
