C9166i Tx power per radio

[RavKam]

Hello,

I've just received new C9166i APs, they have 3 radios installed (2.4G/5G/6G).
Can I set the Tx power per radio or only per AP -so for  all 3 radios ?
Regardless the answer -is this a general rule for all CISCO APs or some models are different and which one ?

THA

Cheers,

  - These APs can only be steered by a controller ;  check if you have  Wireless > Access Points > All APs.
     and select the AP you want to configure ; select the radio                                 2.4 GHz, 5 GHz, and 6 GHz
                                                                                                          and look for Tx power
                                                                                                                     related settings ,

works -thank you
so I can create separate "Tx-power" profiles and assign them per band and per APs based on filters (AP-name) -correct ?

   - I presume you could but remember this is not advisable ; if you leave these parameters alone then
     the controller will regulate them according to TPC (transmit power control) and DCA (dynamic channel assignment) in 
     order to obtain best wireless coverage amongst APs ; a common mistake is : I want maximum power.
     But then you can get into situations where the client can  no longer reach the AP over the distance that it is
     hearing from it ,  (because it has weaker radio power transmitting capabilities , for instance)

It's a high density setup -so definitely no "max-Tx-power" to avoid CCI
DCA is also switched off as we control whole building
Right now we're running 5G only -but I'd like to use roaming between radios to solve (somehow) coverage and number of users per radio  issues (by using macro/micro cells approach)
