## What about SNR?
103103
SNR stands for Signal to Noise ratio and compares RSSI dBm to the RF background noise level and is in dB units (not dBm), higher is better. Notice it compares the background noise level and not the Sensitivity Limit. The reported value changes quite a bit from packet to packet and what values are good depend on what packet rate is being used. The RF chip can only approximate the noise level and only registers a value so high above the noise floor leading to this value getting clipped. Add to that, LoRa modulation can actually receive data below the noise floor to some degree.
