The SNR value obtained using a signal measurement tool is not the actual SNR on a network adapter. The tool obtains the SNR value by comparing the detected signal strength with a predefined noise value (-96 dBm for example). A high SNR value does not indicate a good signal quality because the high SNR may be caused by interference signals. The signal quality should be evaluated by the SNR and signal to interference ratio (SIR).
How Do Signal Measurement Tools Calculate the SNR?
