Executing a FOTA (firmware over the air) method in a LoRa network having low throughput and low power. the transceivers used in the end nodes and in the LoRa gateway are capable of selecting a certain frequency channel and deactivating the LoRa mode. If the spread-spectrum LoRa mode is deactivated, both transceivers at the end node and the gateway function instead using a basic FSK (frequency-shift keying) modulation scheme. This modulation scheme is capable of providing a higher data rate at the expense of reducing the “path balance,” which indicates how much attenuation the transmitted signal may sustain while still being able to be decoded at the receiver. When using the FSK modulation scheme at a high data rate, a FOTA method may be easily carried out, since the end node must have its receiver activated only for a short time.
