WebThe highest Signal-to-Noise Ratio (SNR) possible is at the antenna terminals. All amplifiers add noise, raising the noise floor and thus decreasing the SNR compared to what it was at the antenna terminals. The Noise Figure of an amplifier specifies how much noise is added. WebApr 19, 2024 · If your signal strength is great, but network performance is still spotty, it’s a good idea to check out SNR. To manually measure SNR, measure both signal and noise, and then subtract noise from the signal strength. Example: Signal -60 dBm minus noise -90dB = SNR 30dB; SNR is measured as a positive value between 0dB and 120dB.
