An Evaluation of Self-Built Low-Power Wide-Area Network Based on LoRa

Abstract

<p>With the rapid development of applications in Internet of Things (IoT). Low power consumption and wide area is one of the solutions for the development of information transmission. Therefore, Low-Power Wide-Area Network (LPWAN) technology had led to extensive applications and discussions. The Long Range (LoRa) has the characteristics of self-built network and programmable control of communication parameters besides the above features of LPWAN technologies. The LoRa has more flexible application capabilities compared with the LPWAN technology that requires infrastructure provided by Internet Service Providers (ISP). Therefore, this paper describes the evaluation method from the LoRa parameters and the experiment of long-distance transmission. According to the experimental results, the actual effective transmission distance of the lightweight LoRa module from the packet loss rate is 621 meters. Moreover, the phenomena that different types of antennas connected to the transmitter affect the direction of the device are discussed.</p> <p> </p>
