Cisco 9120 APs Power Levels

antonios.skoulariotis — Mon, 05 Jul 2021 18:52:36 GMT

Team I know the higher the number the Less the power. The Available transmit powers, have always been 8 of them 1 through 8 1 being the Highest and 8 the least power.

As per the below is it safe to assume that the 9120 will not run less than 3.13 mWatts?

Am I missing something?

Available transmit power settings

2.4 GHz

● 23 dBm (200 mW)

● 20 dBm (100 mW)

● 17 dBm (50 mW)

● 14 dBm (25 mW)

● 11 dBm (12.5 mW)

● 8 dBm (6.25 mW)

● 5 dBm (3.13 mW)

● 2 dBm (1.56 mW)

● -1dBm (0.79mW)

● -4dBm(0.39mW)

5 GHz

● 26 dBm (400 mW)

● 23 dBm (200 mW)

● 20 dBm (100 mW)

● 17 dBm (50 mW)

● 14 dBm (25 mW)

● 11 dBm (12.5 mW)

● 8 dBm (6.25 mW)

● 5 dBm (3.13 mW)

● 2 dBm (1.56 mW)

● -1dBm (0.79mW)

Yes, but you need to verify by uni band in the 5ghz. Like in AireOS, you can see the different power levels based on ap model and band to determine the max and the minimum dbm. It can vary depending on the variables I mentioned.

To add to Scott's comments:
Depending on what channel the AP is operating on and depending on the Regulatory Domain.
