Access point power levels

nh6we — Sun, 04 Jul 2021 01:49:53 GMT

I am running a 4400 controller and cant remember how to read the access point power levels. I know the range is 1 to 8 but what represents full power. Is it 1 or 8.

Thanks

There is a lttle catch you need to know on the A side ... Depending on the channel you select the TX power is different ..Here you can read more about this ...

Example --

If you use channel 36 your max TX power is 11 dBm which is power 1 on the controller.

If you use channel 149 your max TX power is 17 dBm which is power 1 on the controller

I hope this helps...
