Snr should be high or low

Generally speaking, you want as high an SNR value as possible. Here's a basic rundown: >40dB SNR = Excellent signal (5 bars).

1. Is higher or lower SNR better?
2. Is higher SNR good?
3. What is an acceptable SNR value?
4. Why is high SNR important?

Is higher or lower SNR better?

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.

Is higher SNR good?

A higher SNR value means that the signal strength is stronger in relation to the noise levels, which allows higher data rates and fewer retransmissions – all of which offers better throughput.

What is an acceptable SNR value?

The range of SNR may vary between 1dB and 30dB. The optimum SNR range is 18–30dB. 18dB is the minimum value at which the device can still operate and deliver relatively optimum performance. Values lower than 18dB can drastically reduce the performance.

Why is high SNR important?

SNR is imperative to distinguish various output signals to achieve efficient output. Signal-to-Noise Ratio is typically expressed in terms of decibels. The higher the SNR value, the better is the output. The reason is that there's more useful information (signal) than unwanted data (noise) in a high SNR output.
