Choosing right power

Hi,

Let's say Supported Country Maximum Power is 20 dBm ,

In Adaptive radio Management profile
Max Tx Power 17 dBm
and Channel 36 Max is 23 dBm
So at the end what will be the power value

Thanks

Re: Choosing right power

The controller will limit ERIP to 20 (radio conducted power + ant gain = 20dB). Even if you configure it for 36 and disable ARM, the controller will set the max EIRP for the AP to 20 (the regulatory max).

 

If you set the max ARM power to 17dB, the controller will set the EIRP of the AP to 17 (radio conducted power + ant gain = 17dB).

Re: Choosing right power

Hi,

 

How did you get the value 27 dB, 

 

Thanks a lot

Re: Choosing right power

That was a typo, should have said 17...it's now corrected.

Re: Choosing right power

Hi,

ARM power to 17dB + ant gain ( 4 dBi) =21 dB?

Thanks

Re: Choosing right power

If you set the ARM power max to 17, or the static power (no ARM) to 17, since the controller knows the AP's antenna gain, it will be 

 

13dB conducted Tx power + 4dBi antenna gain = 17dB EIRP.
