- This paper describes the relationship between drone speed and spreading factor (SF) when multiple drones randomly connect to the same slot to transmit a drone identification message and transmit it through the LoRa method. Basically, it is known that the LoRa communication method has pseudo orthogonality between SFs, so that it is possible to simultaneously receive signals having different SFs. By applying this feature to drone identification communication, it was confirmed that when drones randomly access the same slot, the faster the drone speed, the smaller the range of SF that can be used when an interference signal is received.
