High RTWP

[chronix_ray]

Hi Sirs,

What solution is needed in order to eliminate high RTWP in these scenario.

F1 has high RTWP (average of -68) while F2 is working in normal condition. Huawei System.

Check F1 has high RTWP all day or only busy hours.

Hi Sir,

F1 has high RTWP all day. and F2 has none.

Hi Sir,

Can you check surrounding cells covering to the same area,, if only F1 has high RTWP I think the possibility is due to external interference. If surrounding cells also have high RTWP so you should do frequency scanning.
Please correct me if I am wrong.

Thanks, I thought there has something to do with the parameters.

High load can't not bring RTWP to -68dBm. usually it's external interference. Do check:
- surrounding, same direction cell whether their RTWP affected by same located interference
- swap feeder, hardware to check whether it belongs to hardware or feeder/antenna problem

what is your strategy? have both Frec balanced??? or the most of the traffic is in just one freq?

Had the same problem, but on F2 cells

after investigation, it was a DECT that interfers

while we wait for the interferer to be shut down, i temporarily change the frequency on my F2 cells to F3
Qos improved as soon as i changed (DCR, CSSR, Rach trouble)
only downside is we lost dual carrier as frequencies are not adjacent anymore

How many sectors do you have on your NodeB? Is your F1 and F2 contiguous? I would suspect internal interference if you're not seeing it on any other cells in the area on the same freq.

check the antenna, is there tma inserted or not, if there is tma then tune up the RxAttn parameter also u can check the intra freq neighbor relation in front cells which can make interference also....
