"WebSNR is short for “Signal to Noise Ratio,” and can also be expressed as S/N ratio. It is the ratio of signal power to that of all other electrical signals in the area, known as the noise level. Noise is measured by the Root-Mean-Square (RMS) value of the fluctuations over time. This ratio is expressed in decibels (dB). " - On the signal-to-noise ratio wall
