Parameters versus RTWP degradation in UMTS

@Devender_singh

As far as I understand from all the things you all have mentioned till now, it seems its a kind of external interference.

There are applications in vendors to detect it.

Try in few cells.

For example in Nokia - You have RF monitor app to investigate it.

Indeed.

In some cases repeaters were the cause of degradation.

I remind you once again that the RTWP degradation I mentioned concerns U900 cells only.

Yes, It is possible that external interference is affecting only one particular band.
It may not necessarily be repeaters. It could be a new TV broadcast [just a example] which is using some portion of U900. We faced this issue in our network.

The only way to find the source is RF scan using field measurements and locate it.

Also try to Plot the RTWP hourly pattern, If it improves in some hours?

I’m talking about a real case which was solved by disabling repeater installed on site.

Margin -80 dBm to - 70 dBm.

Surely with value it is either related to the Hardware or configuration.

Check if is it the same antenna model, radio unit…

Have you already checked the overshooting part?
