Engineering thesis
Development of an indoor navigation system prototype based on RFID technology.
The project revolves around developing a straightforward yet fully operational IT system that enables the setup of RFID readers and the tracking of items fitted with RFID tags within the premises.
The system comprises multiple components:
- A desktop application for configuring the RFID reader and setting parameters for accessing the local network (using C#).
- Database which stores data collected from individual devices (PostgreSQL)
- REST server which connects readers to the database, enabling real-time transfer of readings and delivering data in a structured format (C#/.NET language).
- Mobile application that showcases the tagged objects location on the building map (Kotlin)
