* Received Signal Strength Indication (RSSI) minimum = -120 dBm.
If RSSI=-30dBm: signal is strong.
If RSSI=-120dBm: signal is weak.
*
Signal-to-Noise Ratio (SNR) between: -20dB and +10dB.
Closer to +10dB - received signal is less corrupted.
LoRa can demodulate signals which are -7.5 dB to -20 dB below the noise floor.
