It can communicate at a maximum of several tens of kilometers, and features low power consumption.<br>\nThe LoRa signal adopts a special modulation scheme called chirp spread spectrum. Although the amplitude is constant and the frequency is changed, instead of transmitting 0 or 1 by high or low of the frequency as in ordinary PSK, 0 or 1 is transmitted using a signal (chirp signal) whose frequency continuously varies. The signal is transmitted by combining a signal of frequency becoming high (up chirp) and a signal of frequency becoming low (down chirp). <\/p>\n\n\n\n<h2>Solution<\/h2>\n<h3>Comparison of sweep type
