Dears experts.
I’m working on a fixed ISP LTE network. No mobility configured on the network. We have 4 sectors per site with frequency on re-use 2.
Please someone can tell me how to check interference without doing drive test ?

From the statistics, you may know the strength of the interfering.

But, if you want to locate it for the whole city, you must use a high efficiency tool (a scanner).

Hi All.

Anyone did interference testing with Anritsu?

You just need to select bands properly to scan the interference.

Actually I did this testing for Tata and Airtel band spectrum reshuffle duration.

In some specific area we faced interference issue which we are able to seen through spectrum analyzer it’s in 2016~17.

But I don’t have any documentation.
