Hi Experts, Just an inquiry about atmospheric ducting impact in TDD layers. I have observed its impact on UL interference for 4G.pls suggest if any feature and parameters available to deal with this issue. Nokia equipment. [Atmospheric ducting impact in TDD layers]

Use TDD remote interference mitigation feature. Easy way to handle change frame type from 2/7 to 2/5…trade off is DL T’put. Where are you facing this?

OK it may be. Actually this is not the season in normal geography like Gujarat Haryana we are facing in Sep/Oct month. I think few days back storm also came…

Yes, it’s happening for all operators in that area, mainly in TDD layes i.e 2300 and 2500.

Hello, From previous similar conversation here in the forum: [image] Does water affect radio waves? RAN Hello dears. Anyone here knows have some effects or interference of water / humidity in radio waves? Absorption, reflection… and the effects on KPIs? Any comment ap…

If the whole area is affected, go for the feature activation or changing frame type. If only 1 or few sectors (covering same area) is affected, make site health check (jumpers, feeders, connectors, alarms, vswr, external source of interference.

Thanks! Impacted whole costal area.

How is the weather there? Is the problem occuring tje se period every year? Or every season? What is the affected band?

Band is 2300. It’s mainly due to storm in now a days storm is very frequent. Any other suggestions which will reduce this ducting effect (it is “atmospheric ducting” phenomenon). Will try to implement @krunal_shah suggested parameters asap and share the outcomes to all.
