For those who are using only 20 MHz in the 5 GHz space, I’d be interested to know what your channel planning looks like.

I would say based on data that I see, a default config of 20 MHz channelization is a good best practice with 40 MHz done strategically if necessary. Just my $.02.

Our campus presently uses 20MHz channel width in all buildings. We are testing and considering 40MHz width because of the bandwidth benefits for clients. What do you use on your campus? Have you found that setting a 40MHz channel width on your 5GHz radios has caused too much interference?
