During the site survey, we used the 1230 and assigned tx power based on 100mw, 50, 30, 10, 5.. so on.. on the AP. But when we implemented the controller-based, the transmit power were replaced with 'tx power levels', 1,2,3,4... so on... I read somewhere that 1 is the max and as the level increases, its tx power becomes 50% less. say, 1=100mw, 2=50 mw, 3=25mw, 4=12.5, 5=6.25 and so on...
the confusion is, some AP's tx power were set to 30mw during the site survey. Which level should be the euqivalent as 'tx power level' on the wlc-base deployment? is it safe to assign the 30mw site survey data to the #3 'tx power level' on the controller?
And does anyone has ideas on the effect of using or assigning the country codes of the controller. If US is used, what is the max power level value? is it 100mw? And if US is used as country code, can any AP on any country domain be used. I checked out the chart, but it's quite confusing.
Thanks for anyone who can shed light on this.... Argh!
