• Goal✓ Deploy IoT network infrastructure to transmit environmental radiation data using

KREONET

✓ Reliable and safe transmission of environmental radiation data

• IERNet (Integrated Environmental Radiation Monitoring Network)✓ Operated and managed by KINS (Korea Institute of Nuclear Safety)

✓ Collect and monitor environmental radiation data in Korea (170 sites)

✓ www.iernet.kins.re.kr

• A Radiation Monitoring Site

✓ 1st, 2nd and 3rd generation radiation sensors

✓ Connected by RS-232C between a sensor and 2G Modem module

Radiation Sensor

2G modem

• Problem Description✓ 3rd generation radiation sensors have compatibility problems with 2G modem

✓ Reduce investment of 2G mobile network and service

• How to Solve the Problem?✓ Replace 2G network with IoT technology (LoRa/LoRaWAN)
