I am reading a section that says that when you change a power level from 1 to 2 for a specific AP, the power decreases by 50% ans so on. My question is: If FCC says that transmit power should not exceed 30 dBm (I guess that is power level 1 in the AP), then setting the power level to 2 would mean the power is reduced to 15 dBm
So, the power that is cut in half by going from power level 1 to 2 is in mw and not in dBm. The statement that each 3dbm of change results in either a Halving or Doubling of of the power, and the example made it very clear . Thank you.
