Mist AP Transmit Power Notation

Transmit power throughout the Mist GUI and API is represented per Tx Chain. 

Here is how to convert to other common industry notations:

      • Total Power Out (TPO) = per chain tx power + 10log(num. Tx chains)
        • Rule of thumb, add 6 dB for AP41 or AP43 and 3 dB for AP21 for MIMO gain
          • 4ss AP = 6 dB of MIMO Gain
          • 3ss AP = 4.7 dB of MIMO Gain
          • 2ss AP = 3 dB of MIMO Gain
        • Example: 17 dBm per chain + 6 dB MIMO gain = 23 dBm total power out
      • EIRP = total power out + antenna gain – antenna losses
