Please suggest me what might be the problem if our link balance is in negative for Stand Alone Sites.
Could it be a H/w fault. And what if link balance is more than the threshold(8).
Please if anyone can let ,me knnow with the reasons when our link balannce crossed the thresholds value. And what might be the reason if uplink is better than downlink. Is there a chance for the hardware fault.
Thanx for the reply. The Vendor is NORTEL. We are not using TMB on the antenna path. Mostly this problem, link balance above threshold, exists in the stand alone sites. We are using HD(or By Pass) for the stand alone sites with the configuraion of 2 by 2 by 2. Please let me know what might be the prob tht im getting -ve Link balance and other greater than 8. VSWR and OP is ok.
Limitation in link budget (which is smaller).
if it UL => check your diversity,LNA & BTS RX
if it DL => check your BTS power,TMA, compiner & BTS TX.
# VSWR doesnt impalance your budget, it degrade both side UL & DL.
