Research and Development of Lora-Modulated Signal Retransmission System

This article focuses on an issue within the LPWAN wireless technology based on LoRa, which often faces challenges in maintaining stable data transmission due to unstable communication conditions between nodes and gateways, and a simulation of node connections and the influence of noise levels to connection stability is presented. In traditional LoRaWAN networks, where devices connect directly to gateways, signal quality deteriorates as distance increases or interference occurs. This leads to data loss and reduced communication reliability. One way to solve this problem is by transitioning to mesh networks, where devices can transmit data not only directly, but also through neighboring nodes. This approach allows for flexible adaptation to network changes and restoration of interrupted connections. However, the correct operation of this technology largely depends on the chosen routing algorithm and whether real-world signal transmission conditions are taken into account.
