LoRa1278 adopts Semtech RF transceiver chip SX1278, which adopts
LoRa TM Spread Spectrum modulation frequency hopping technique. The
features of long distance and high sensitivity (-139 dBm) make this
module perform better than FSK and GFSK module. Multi-signal won't
affect each other even in crowd frequency environment; it comes
with strong anti-interference performance.
