A Wireless Solution for Industrial IoT Using LoRa at 2.4 GHz

This thesis was carried out in the context of a project developed by the university of Bologna upon commission of GD SpA, aimed at providing a new proprietary solution for a Industrial Internet of Things monitoring application. The focus is on the definition and implementation of a wireless communication protocol, which has been called LoRaIN, based on LoRa technology at 2,4 GHz and suitable for Industry 4.0 applications. LoraIN proposes a centralized approach to Network management, with a single entity keeping synchronization among devices and scheduling all the transmissions according to separated time slots, in order to avoid collisions. Distinctive features of the protocol are also its multi-hopping functionality and the possibility to deploy batteryless devices, charged via Wireless Power Transfer technology. Numerical results reported in the thesis demonstrate how LoRaIN protocol meets the application requirements.
