With the spread of embedded systems, there is a growing interest and demand for Internet of things. Technologies such as Wi-Fi, Zig-Bee, and Bluetooth can transmit relatively large amounts of data, but consume high power and have a narrow communication range. As a result, LPWAN technologies such as LoRa, Sigfox, NB-IoT, and Wi-SUN are emerging as attractive communication methods in the Internet of things. In this paper, we use LoRa, one of the low power long distance wireless communication technologies, to construct the self wireless network including gateways and measure the performance to transmit data of electric safety IoT devices. Instead of using the existing commercial network, we used the 900MHz frequency band to communicate with the gateway. In order to evaluate the performance of the implemented system, we verified the packet SNR and the RSSI value by changing the communication between the electric safety IoT device and the gateway inside and outside, inside and outside of the distribution panel, and distance.
