Research of LoRa Signal Detection Method and Development of Equipment for It

Abstract

Recently, a wireless communication system called LoRa has been adopted for various IoT devices. We are studying the way to change communication parameters according to the radio wave usage. In that research, a method to detect the radio wave usage status of LoRa signal in each SF is developed, even if multiple SFs are mixed in one channel. Furthermore, the method is implemented in the equipment named “LoRa Finder.” In this paper, we describe the detection method in detail and explain the hardware and software of the equipment to realize it.
