Note that there may be short term bursts of noise that may drop the margin, but due to the sampling time of the management utility in your modem, will not necessarily show up in its interface. In some instances interleaving can help raise the noise margin to an acceptable level. The higher the SNR margin the more stable the connection. For example, to calculate SNR margin: If actual measured SNR = 45db SNR to sync at 8Mbit/s = 35db SNR margin = 45-35 = 10db Higher SNR/SNR margin numbers indicate cleaner/stronger signals, with less background noise. Some NAT wireless routers, for example (notably dd-wrt open source router firmware) use SNR margin, only denoted as ' SNR'. SNR margin is often confused and used interchangeably with SNR. It is in essence a buffer that allows for fluctuations in SNR without dropping the connection. It can be simplified to: the difference between actual signal and signal required to sync. noise margin) is the difference between the actual SNR and minimal SNR required to sync at a specific speed. Signal-to-noise ratio ( SNR) is defined as the power ratio between a signal (meaningful information) and the background noise (unwanted signal): SNR = signal / noise 6dB or below SNR is bad, you will experience no sync, or intermittent sync problems 7dB-10dB is fair but does not leave much room for variation in conditions 11dB-20dB is good with little or no sync problems (if no large variation) 20dB-28dB is excellent 29dB or above is outstanding The more commonly used SNR margin, as described below is sometimes abbreviated as simply SNR as well.

Noise (dBm) in communications is a combination of unwanted interfering signal sources, such as crosstalk, radio frequency interference, distortion, etc.
