SNR or Signal to Noise Ratio is signal levels relative to each other (signal and noise) so it gives you a better idea of the quality of the signal without having to know the actual values of the signal or the noise. A receiver requires a certain SNR to guarantee operation (a performance measurement of the receiver) and a minimum signal level (another performance level of the receiver). With that you can tell what the maximum noise level the receiver with operate in given a signal level. A higher SNR is better. So I agree SNR is generally a better measure assuming minimums are met.Doesn’t below explain the noise level in the wireless log vs RSSI? Wouldn’t a higher -, less noise, be better? Granted, I’m just learning here. Maybe I’m reading the wireless log incorrectly or that noise value there is something different? Thanks.
