  Abstract

LPWAN(Low Power Wide Area Network) is an M2M(Machine to Machine) networking technology for the Internet of things, and it is optimized for the Internet of Small Things. It aims to transmit a small amount of data at low-power, long distance and low cost, and of a small amount of data, there is typically LoRaWAN(Long Range Wide Area Network). LoRaWAN is currently being used to build M2M services in outdoor environments such as urban areas, ocean, and remote areas. Also, the performance research of physical layer is actively performed by classifying LoS(Line of Sight) and NLoS(Non Line of Sight). However, despite the increasing demand for indoor services such as smart factories and buildings, research on indoor communication performance is insufficient. Especially, indoor wireless communication stability has different characteristics depending on the material and number of walls or layers. In this paper, we construct LoRa performance monitoring and analysis system, which is a physical layer technology of LoRaWAN, and we analyze communication performance based on empirical experiment in indoor environment. The experimental environment is limited to the concrete buildings commonly seen in the surrounding area, and the number of walls and floors according to the compartment materials is considered. This paper evaluates and analyzes the performance by LoRa factor, Packet RSSI(Received Signal Strength Indication) and PDR(Packet Delivery Ratio) according to the indoor environment.
