What is ahRadioNoiseFloor?
This object measures the ambient RF noise level at the radio interface, reported in dBm (with values offset by +256 to handle negative numbers in the 0–256 range). It indicates environmental RF interference and helps diagnose channel congestion or external interference sources. An example reading is 165 dBm (representing -91 dBm actual noise floor).
