Hello Experts.
Is it recommended/required PCI Planning in network if we change BW, like from 5 MHz to 20 MHz?

2

Not required.

3

No need PCI Planning.
Only power audit is crucial to keep the same coverage.

4

Ok, thanks.
One more question: is it possible to deploy 18.8 MHz instead of 20 MHz?
If yes, how and what are the challenges?

5

No need to do Replaning of PCI. It’s not BW dependent.

6

Yes, possible.
