Abstract

Wireless communication is a core technology constituting the Internet of Things (IoT), but there is no suitable educational equipment to learn various wireless communication technologies used in the Internet of Things through practice. This paper deals with the development of advanced education and training equipment that can perform various IoT wireless communication practices. It uses an Arduino mega board as a device to control various sensors. As wireless network technologies to send and receive the sensing date wirelessly, it makes use of RFID/NFC and Bluetooth among WPAN technologies, WiFi among WLAN technologies and LoRa and 2.4GHz wireless transceiver among WWAN technologies. In addition, GPS, infrared communication, I2C communication, and SPI communication are organized so that various IoT wireless communication technologies can be learned through practice. In addition, since the educational equipment developed in this paper is equipped with two devices, it is designed to perform transmission and reception experiments for wireless network technology within the equipment.

무선통신은 사물인터넷(IoT)을 구성하는 핵심기술이나 사물인터넷에 활용되고 있는 다양한 무선통신 기술들을 실습을 통해 학습할 수 있는 적합한 교육장비가 존재하지 않는다. 본 논문에서는 다양한 IoT 무선통신 실습을 수행해 볼 수 있는 첨단교육훈련장비 개발을 다룬다. 다양한 센서들을 제어하기 위한 디바이스로 아두이노 메가 보드를 사용하며 센싱한 데이터를 무선으로 송수신하기 위한 IoT 무선네트워크 기술로 WPAN 기술 중 RFID/NFC, Bluetooth 무선네트워크 기술, WLAN 기술 중 WiFi 기술을 사용하며 WWAN 기술 중 LoRa와 2.4GHz 무선 트랜시버를 사용한다. 그 밖에 GPS, 적외선통신, I2C 통신, SPI 통신에 대하여 실습을 통해 다양한 IoT 무선통신 기술들을 학습할 수 있도록 구성하였다. 또한 본 논문에서 개발한 교육장비는 2개의 디바이스를 장착하고 있어 장비내에서 무선네트워크 기술에 대한 송수신 실험을 수행해 볼 수 있도록 설계하였다.
