WebIf SNR is smaller than 0, the received signal operates below the noise floor. Normally the noise floor is the physical limit of sensitivity, however LoRa works below the noise level. Typical LoRa SNR values are between: -20dB and +10dB. A value closer to +10dB means the received signal is less corrupted. boral roof tile stockton
