Noise offsets

The radio modules in the WLAN devices can specify the signal and noise levels as absolute values (in dBm). However, the receivers are not calibrated ex-factory. To specify optimal values for noise and signal levels, the noise offsets table can be used to set correction values (in dB) for each frequency band (2.4 / 5 GHz), channel, and WLAN interface. These values are added to the noise and signal values as supplied by the radio modules.
