Development of the LoRaWAN-based Movement Tracking System

摘要

The LoRaWAN (Long Range Wide Area Network) is a new technology in Wireless System. This LoRaWAN testbench project consists of Arduino Microcontroller, Dragino YUN Shield, and LoRa Shield to operate as the LoRa Gateway. LoRa Client requires Arduino Microcontroller and LoRa/GPS Shield. LoRa/GPS will be powered by LoRa Client, and it will send the GPS location information to the LoRa Gateway where the location received will be recorded in its DataLog periodically. The LoRa Client will be mobile while Gateway Server will be at stationary mode during the experiment. The testing evaluation will be done in suburban and urban scenarios. It was found that in a suburban scenario, the communication between two devices has a better performance compared to the urban scenario. LoRaWAN communication in the urban area shows that with higher interference due to high rise buildings available, the communication will be less efficient. This issues can be solved by installing LoRaWAN tower in the middle of the area. However, this work shows that LoRaWAN platform has the potential to replace the use of IoT infrastructure on the existing 802.11 Wireless Standard, as currently the LoRaWAN can be enabled at three different frequency band, 433MHz, 868MHz and 915MHz.
