What is an acceptable SNR?

Generally, a signal with an SNR value of 20 dB or more is recommended for data networks where as an SNR value of 25 dB or more is recommended for networks that use voice applications. Learn more about Signal-to-Noise Ratio.

What is a bad SNR?

Signal to Noise Ratio

The signal-to-noise ratio (SNR) is the power ratio between the signal strength and the noise level. This value is represented in decibels (dB). In general, you should have a minimum of +25dB signal-to-noise ratio. Lower values than +25dB result in poor performance and speeds.

What does high SNR mean?

A signal-to-noise ratio over 0 dB indicates that the signal level is greater than the noise level. The higher the ratio, the better the signal quality.

What happens when SNR increases?

When SNR increases, the channel's data throughput also increases. This means that for a given signal level, an increase in noise will decrease the data throughput. The higher the noise level, the less space there is for the actual data that is being transmitted on the channel.
