This thesis project was realised at Alten Italia R&D department in Bologna, with the intent of implementing an IoT asset-tracking system addressing the underlying principles of Industry 4.0. In global manufacturing and commerce, raw materials, components, and final goods can travel long distances, through warehouses and logistic hubs before arriving at their destination. The deployment of a fleet of programmable IoT devices able to track and store data of many unit loads provides a company valuable information for planning and optimization. This project studies the implementation steps around an IoT device capable to determine and send real-time position and condition of Unit Loads along the supply chain.
