This thesis addresses the lack of high-quality, open-source tools for planning LoRa networks that would allow for simple coverage simulation and terrain analysis. As a solution, here we design and develop a Web application that integrates the open-source tool SPLAT! with a modern user interface (Vue.js) and a backend system (Python). The application enables various types of signal simulations, selection of optimal device locations, and line-of-sight verification between points. The tool is validated with field measurements, which confirm a high correlation with the predictions. The contribution of the thesis is a functional, open-source, user-friendly, and extensible tool for radio planning of LoRa networks.
