SNIR: Signal to Noise + Interference Ratio
Signal-to-Noise + Interference Ratio (SNIR) is the ratio of usable signal being transmitted to the undesired signal (noise) plus interference from other or the same channels. It is a measure of transmission quality. The ratio of good data (signal) to bad (noise + intereference) on a line is expressed in decibels (dB).
