Abstract

Since the ocean accounts for 70.8 percent of the earth's surface, the success of IoT technology in the marine industry is to collect information from devices placed in a wider range. LPWA is a feature with a wide range of communication and is very suitable for deployment in the ocean. In this paper, the real-sea performance distance experiment was carried out based on Private LoRa, a key technology for executing the electronic phrase real-name system. A private LoRa module based on sx1276 was developed, and Gateway was developed to transfer data received by private LoRa to the server using SKT Cat. M1. After installing gateways at 599 meters above sea level and experimenting with data transmission and reception at 25 km, 40 km and 60 km, we were able to see that the communication success rate was obtained to be 96.1%. 97.1% and 96.2% respectively.

해양은 지구 표면의 70.8%를 차지하기 때문에 해양산업에서 IoT 기술의 적용은 넓은 영역에 배치된 수많은 장치로부터 다양한 정보를 수집하고 활용하는 것이다. LPWA는 통신 거리가 넓은 특징으로 해양에 배치하기에 매우 적합한 통신이다. 본 논문에서는 전자 어구 실명제를 실행하기 위한 핵심기술인 private LoRa를 기반으로 실해역 성능 거리 실험은 진행하였다. sx1276을 기반으로 한 private LoRa 모듈을 개발하였고, 게이트웨이는 private LoRa로 수신 받은 데이터를 SKT Cat. M1을 이용하여 서버로 데이터를 전송하도록 개발하였다. 해발 599 m에 게이트웨이를 설치하고 25 km, 40 km, 60 km에서 데이터 송수신 실험을 한 결과, 각각 96.1%. 97.1%, 96.2%의 통신 성공률을 보이는 것을 확인할 수 있었다.
