How best to configure access points

[zntrx]

I have 3x Cisco MR42 APs flashed with 24.10.5.

They’re to be setup essentially in a straigt line, around 15m apart.

The APs all have 3 Radios, 1xQCA9990 b/g/n, 1xQCA9990 ac/n and 1xQCA9887 ac/b/g/n.

I would expect that day to day across all 3APs there will be a maximum of 10 clients, this might increase to a max of 30 clients at times.

Is there likely to be any benefit in enabling all 3 radios on the APs? Is there anything I should be aware of other than setting non-overlapping channels on each AP and enabling FT?

If enabling only 2 radios is here likely to be any difference between the QCA9990 and QCA9887?

I expect that this is mostly basic info, so please excuse my ignorance.

Thanks!

Yes, one seems to be 2.4 GHz and the other 5.4 GHz.

I assume one of the 5.4 GHz radios are for backhaul anyway.

It looks like the QCA9887 can do 2.4 GHz or 5 GHz. The QCA9990s are frequency specific.
