LoRa 통신 기반 사물인터넷(IoT) 실습 교육에 관한 연구 = A Study on the Internet of Things (IoT) Lab Education based on LoRa Communication

다국어 초록 (Multilingual Abstract)

The representative technology of the WWAN wireless communication network used in the Internet of Things is LoRa communicationtechnology, and LoRa communication uses the ISM band. The 920 MHz (920.9 MHz~923.3 MHz) band frequency, whichis used as a domestic LoRa frequency, had a problem in performing LoRa network practice in the curriculum using a commerciallyavailable LoRa modules that have been used in Europe and the United States because of different frequency band, but a RYLR896LoRa module was developed that allowed RF frequency to be programmed. With this module, this paper confirmed that the frequencycan be set at a specified frequency in Korea using AT commands. In addition, using these RYLR896 LoRa modules, a LoRanetwork consisting of end nodes and gateways was constructed and practiced to confirm that development equipment capable ofpracticing the RYLR896 LoRa module and IoT was operating normally.
