Feasibility-Study and Developing of a LoRaWAN® IoT Sensor Node

The increasing implementation of IoT technologies guarantees a growing number of connected devices. These devices range in features depending on their respective applications. Because of the growing interest and rapid technological advancement of sensor technology, the designing, and deployment of wireless sensor networks has also seen a substantial expansion. This thesis focuses on developing a sensor-node for a LoRaWAN network, which is one of the dominant low-power wide-area network technologies. It does so by taking into account an existing end-device and based on its design and essential performing features, a new design is proposed and implemented. It comprehensively discusses power consumption, size, hardware and firmware development and on how all the mentioned contribute to the overall significance of the end-device. Ultimately, the proposed design is tested by establishing a complete LoRaWAN network to observe and evaluate the performance upon actual deployment.
