Web6 de mai. de 2024 · In comparison LoRa technology allows for signals to be received that are as much as 20dB below noise level, thus the LoRa signal could be up to 25dB (5dB + 20dB) weaker than the FSK one and still be received correctly. If LoRa can decode a signal that is 25dB weaker, then the transmitter can be further away than in the FSK example. sutton and wandle valley ramblers
