Ec/No in 3G site in 1 sector :(

[cool_guy4ever15]

Hi all how are you,

I faced a problem in 3G Site the site has 3 sectors sec A and C are Good in ecno while Sector B has a problem the quality is very bad , the RBS is 3107 we changed the RU & FU of this sector but also the same we removed the Installed TMAs but also still a problem the RBS has no alarms , this sector serve an electricity station i thought this is the problem may be interference but the Drive tester told me that Both sectors A & C serve very well inside the station, am going to perform VSWR test now to check the feeders but i was wondering what may cause this problem if anyone faced it before i really appreciate the support ..

Hi,

I would recommend to check PSC plan of the particular cell having degraded EcNo value.

Thanks
