Detection of Signals from a LoRa System Under Interference Conditions

Abstract

The paper examines the factors that affect the detection of signals in devices using modern LoRa technology to exchange information between devices that are part of the Internet of things in an interference environment. Features LoRa technology is a long range of information exchange in comparison with similar technologies, which is achieved through the spreading spectrum, the transmission of information in short packages and suppression of multipath signal propagation. The article notes the contribution of each factor to the quality of reception and studies the reception of the messages at the LoRa technology in a city with the significant interference that created by means of cellular communication and Wi-Fi devices.
