WebOct 5, 2024 · Cisco Meraki Access Points reference the Signal to Noise Ratio as the indication for the quality of the wireless connection. This provides a more accurate depiction of the health of the wireless signals as it takes the RF environment and ambient noise levels into account. For instance, a received signal of -65 dBm can be considered good at a ... Websignal-to-noise ratio (S/N ratio) The ratio, at a selected point in the circuit, of signal power to noise power. It measures the comprehensibility of a data source or transmission link, usually expressed as the root-mean-square signal amplitude divided by the root-mean-square noise amplitude. The higher the S/N ratio, the less the interference ...
